With a total depth of 5,941 meters, Mærsk Gallant has beaten the record for deepest well ever drilled on the Norwegian continental shelf.

On 31 July, Mærsk Gallant drilled the Solaris ultra HPHT (high-pressure, high-temperature) well to a total depth of 5,941 meters TVD (True Vertical Depth).

This means that Mærsk Gallant has beaten the record for deepest well ever drilled on the Norwegian continental shelf.

"We have broken a number of records during the Solaris operation. But this achievement is second to none. There was a lot of cheering in the driller's cabin that day," says Sadi Ozturk, Assistant Rig Manager on Mærsk Gallant.

He continues:

"The Solaris exploration well is one of the most challenging wells in the North Sea. All crew members are very excited about this achievement."

Demanding requirements

In the Solaris project – together with the customer, Total E&P Norge – Maersk Drilling has taken a 15,000 psi rig and adapted the equipment and procedures in order to drill a reservoir section where predicted pore pressures are well in excess of 15,000 psi.

The demanding requirements of the customer have led to a wide variety of modifications on the rig.

The record list

Given the extreme circumstances, the rig team on Mærsk Gallant has set several records during the operation.

The list includes:

1: the largest and most complicated BOP stack rig up.

2: the biggest cement job (600 m3 cement slurry).

3: the heaviest casing run (1,2M lbs).

4: first time a 20K BOP has been nippled up (installed) and used to drill an ultra HPHT well.

At the moment, the crew members on Mærsk Gallant are in the process of plugging and abandoning the well and expect to commence the rig move in the beginning of September.

The Njord A platform arrived at Kværner Stord on Thursday 25 August. The platform will now be reinforced and renovated for production beyond 2030.

Oil and gas production on Njord should in fact have ceased a long time ago. When the field was developed, it was scheduled for production until 2013.

“We have been able to recover more of the reserves than originally expected, and following new discoveries and the Snilehorn development, field production will continue for at least ten more years. This is a big and important project and Statoil is working closely with the partners and suppliers to succeed,” says Snorre Grande, project director for the Njord Future project. The commercial basis for the Njord A renovation still requires production from Njord and Hyme, where we have identified 177 million barrels of oil equivalent (boe) remaining to be produced.

Scheduled for tie-in to Njord, the Snilehorn discovery contains 66 million barrels. These two fields combined will provide more recoverable resources than the Gina Krog field, which is currently under development on the Norwegian continental shelf.

To enable Njord A to receive these resources, the hull must first of all be reinforced. Extensive renovation on board the platform will also be made.

A new chapter in the history of Njord

Njord has been on stream for 6821 days and 54 wells have been drilled, including exploration wells. A total of 167 million barrels of oil and 41 billion standard cubic meters of gas have been produced since the start-up almost 20 years ago.

We are about to pass a key milestone in the history of Njord as the Njord A platform comes “home” to Kværner Stord, where it was constructed in 1997. At that time the yard was called Aker Stord. In April this year Kværner Stord was awarded the framework contract for renovation of the platform and pre-engineering will continue throughout this year. The framework contract also includes an option for the platform renovation work.

“We have been preparing the platform on the field since March. Marine operations have been carried out safely and successfully, and well within the planned execution period. It has been great to take part in the Njord A platform’s voyage to Klosterfjorden, where Kværner is now taking over,” says Knut Lorang Alvheim, project manager for marine operations on board Njord A.

The Njord Future project will also be prepared for further phasing-in of third-party fields. A new and fortified Njord platform may furthermore become a field centre in the future for new discoveries in the area.

Njord Bravo

Production on Njord and Hyme was shut down in June and preparations for the Njord A tow-in have continued through the summer, including tasks such as securing of wells and facilities before the actual disconnection.

The Njord Bravo storage vessel arrived at Umoe Sterkoder in July. Extensive work is currently being made to examine the vessel’s condition closely. A decision will be made this year whether it is possible to extend the life of the storage vessel or we need to construct a new vessel.

8Scour TiresAward-winning technology developed in the east of England is to be presented as a cost-saving solution for North Sea decommissioning at a major industry conference in Scotland this week.

Scour Prevention Systems will showcase how its patented scour prevention mats using end-of-life tires offer alterative effective protection for decommissioning oil and gas pipelines to delegates at this week’s Decommissioning: Technology Innovation Platform event hosted by Decom North Sea and the Oil and Gas Innovation Centre.

The company, based at OrbisEnergy, Lowestoft, is one of 10 companies chosen to present technology that has the potential to help companies achieve the 35% decommissioning cost reduction targeted by the Oil and Gas Authority (OGA).

Speakers at Thursday’s event at Aker Solutions’ building in Dyce, Aberdeen, include Colette Cohen, chief executive of the Oil and Gas Technology Centre, and Jim Christie, OGA head of decommissioning. Scour Prevention Systems’ John Best and Alistair Punt will explain to delegates the potential savings of tire mats compared to traditional methods such as concrete mattresses or rock armor.

They take less time to install, have no threat of pipeline damage and need no direct remedial works. Furthermore, with an increasing number of cables of offshore wind being installed, the mats provide an effective crossing bridge at an interface with a decommissioned pipeline, they will tell delegates.

“Our aim is to raise awareness that our product is out there as a proven, market-ready and cost effective solution to be considered when people planning decommissioning are evaluating solutions,” said Mr. Best. “Our technology of matrices of recycled vehicle tires has proved to be very successful and is something we believe potential users need to be made aware of so they have a wider choice.”

“When pipelines are being decommissioned, our mats’ design helps to reinstate seabed cover and leave the pipeline secure and protected in a non-obtrusive manner.”

“The product effectively stabilize the seabed over pipelines forming a secure protective layer, protecting the pipeline from exposure and damage, providing a cost effective and easy-to-install solution to pipeline decommissioning.

The mats have been trialed and successfully demonstrated in the North Sea and used to remediate and prevent further scour around offshore wind foundations, and protecting telecoms cables subsea infrastructure.

Lightweight and modular, they require one-off installation without divers or trenching and provide a smooth contour created by the unique properties of the patented design. The mats also protect the pipeline from dragged anchors, fishing equipment and hydrodynamic forces.

Scour Prevention Systems have developed their effective product range, consulting with industry, clients and with assistance from research bodies including expert advice from the Offshore Renewable Energy Catapult. They also secured a SCORE grant to help it take its technology to the next phase two years ago and support the development of appropriate lifting and decommissioning procedures

A new £6m SCORE program launched earlier this year at OrbisEnergy will help companies develop their innovations.

The tire mat invention was a previous winner of the East of England Energy Group’s (EEEGR) Innovation Award.

Mr. Best, a former EEEGR CEO, said: “I am particularly delighted that, in my previous role with EEEGR, Scour Prevention Systems’ mats was an innovation award winner and seeing it moving forward into the industrial deployment is particularly exciting.”

Statoil aims to conduct a major exploration campaign in several parts of the Barents Sea in 2017. The company is also strengthening its position in the area through several transactions with other companies.

“We have worked systematically on developing an exploration portfolio for testing good and independent prospects in 2017 and 2018. For 2017 we see promising prospects in different parts of the Barents Sea. For example, we want to explore the Blåmann prospect in the Goliat area, Koigen Central in PL718 on Stappen High and the Korpfjell prospect in PL859 that was awarded in the 23rd licensing round,” says Jez Averty, Statoil’s head of exploration on the Norwegian continental shelf (NCS).

In addition to an exploration well in PL849 (Blåmann), awarded in the Award in Predefined Areas (APA) in January 2016, Statoil and the operator ENI have also agreed on drilling a new exploration well in PL229 (Goliat) in 2017. Statoil has already a rig on contract which is suitable for operation in the Barents Sea. The company is working on obtaining approval from partners and authorities for an exploration campaign in 2017 covering between 5 and 7 wells in the Barents Sea.

During the past months Statoil has entered or increased its share in five licences in the Norwegian part of the Barents Sea by a number of agreements with Point Resources, DEA, OMV and ConocoPhillips.

“Giving us access to new acreage, the transactions demonstrate our belief in continued exploration potential on the NCS. We have played a leading role in the Barents Sea for 40 years, and we are still a guarantee for high activity in the area,” indicates Averty.

New and major discoveries are crucial to maintain the current NCS production level up to 2030 and beyond. The areas off North Norway will play a key role in reaching this ambition.

“Through these agreements we are strongly increasing our presence in the Hoop area, we are fortifying our position around Johan Castberg, and we see new opportunities in the southwestern part of the Barents Sea,” says Averty.

Statoil completed a comprehensive exploration campaign in the Barents Sea in 2013-2014 without any impact discoveries, but with additional volumes to Johan Castberg through the Drivis discovery. Exploration is a long-term process requiring patience, and information from the previous campaign has been used to further deepen the company’s understanding of the petroleum potential of the Barents Sea.

“We are working actively on replenishing our exploration portfolio through government awards, developing new ideas in existing licences and making agreements with other companies on acquiring licences. This provides a good basis for exploring more interesting opportunities,” says Averty.

“We have also worked efficiently on reducing costs by developing new technology, such as Cap-XTM, and improving drilling efficiency. The wells to be drilled in the south-eastern part of the Barents Sea next year seem to be the most inexpensive offshore exploration wells throughout Statoil,” continues Averty.

Through the Barents Sea Exploration Collaboration (BaSEC) the industry has formed a good basis for carrying out safe and consistent drilling operations. The industry’s joint seismic data gathering in 2014 further demonstrates its will and ability to solve common issues efficiently while taking into account other interests in the same areas.

All agreements are subject to government approval.

3GustoMSC Ocean 1600Driven by the increasing requirements for harsh environment GustoMSC launches a new harsh environment drilling semi-submersible series: the OCEAN-HE. Based on the extensive experience in harsh environment and existing OCEAN designs, these units will add true value to the market in terms of safety, workability and efficiency.

The OCEAN850-HE and OCEAN1600-HE form the basis for respectively the mid water and deep water harsh environment regions of operations. The semi-submersible hull shape is especially designed for low motion characteristics and optimum station keeping capabilities.

The OCEAN1600-HE is the top of the range and the largest drilling semi design by GustoMSC to date. With a maximum displacement of approximately 70,000 tons, a large derrick, DP3 and a 16 point mooring system for station keeping, combined with a large deck area and large variable deck load, it aims at the high spec deep water spectrum. It is designed to cope with the North Atlantic environmental conditions. With the OCEAN850-HE a cost efficient midwater harsh environment design is provided. In the current market CAPEX needs to be controlled as well as the OPEX, to enable to work profitably at a reasonable day rate. It resulted in a moored-only harsh environment semi-submersible of approximately 50,000 tons displacement with a water depth rating of 1,000 meters and a 6th generation efficient single derrick combined with horizontal riser storage.

GustoMSC has been involved in the design and engineering of semi-submersibles since the 1970s. In the mid-1980s, Keppel Fels-DTG and GustoMSC teamed up to develop the DSS series of drilling semisubmersibles, including the Maersk D-rigs, the Gold Star and the Floatel DSS20-NS designs. This successful development is still continuing.

GustoMSC’s proprietary OCEAN series, started in 2008, has also become a success story with five units built and introduced within weight, budget and time. With the introduction of the OCEAN-HE series GustoMSC is able to provide full coverage of the harsh environment drilling spectrum.

12DNV gl all basPressure is mounting on the global oil and gas industry to reduce environmental footprint at the same time as the industry is under significant cost pressure. Since business as usual is not an option, DNV GL has launched two papers to advise the industry on how and where to make impactful changes within financial constraints.

The paper, ‘A cost-efficient approach to reducing environmental impact’ provides a framework for the industry on how to improve environmental sustainability by identifying the most cost-efficient mitigating measures. To demonstrate how the abatement framework can work in practice, DNV GL has also carried out a case study for an offshore asset. The second paper, ‘CO2 abatement potential for offshore upstream installations’ demonstrates the results of a comprehensive case study on how CO2 emissions can be reduced through the implementation of a number of cost-effective measures for offshore production on the Norwegian Continental Shelf (NCS).

Elisabeth Tørstad, CEO, DNV GL – Oil & Gas, says: “Cost management is a top priority for the industry right now but it’s still possible to reduce our environmental footprint without breaking budgets. Cost-effective measures can be implemented across the lifecycle of assets and throughout the supply chain. Our papers will advise and support decisions in this critical area. Greater transparency by the industry on environmental risk management processes and sustainability reporting will give the sector much needed credibility and speed up sustainability improvements as a business advantage.”

The framework proposed in ‘A cost-efficient approach to reducing environmental impact’, is based on internationally recognized guidelines (IPIECA, API and IOGP) for sustainability reporting. It can also be used alongside other sustainability reporting initiatives or company specific sustainability KPIs. Aligned with UN Sustainable Development Goals for the environment, it covers a wide range of indicators, including emissions to air and discharges to sea (i.e. hydrocarbon spills, produced water, etc) for specific offshore assets. It is based on a three-step integrated approach: reporting and accounting of emissions and discharges; impact and risk assessment; and prioritizing cost-efficient environmental improvements.

“Our approach allows better informed decisions to be made on how and where to improve the environmental performance of a single or multiple mix of assets,” explains Tørstad. “This will support operators in reporting and communicating with stakeholders, as well as in their efforts for continuous improvements and benchmarking. It will also increase control and opportunities for improving global environmental risk management.”

The pathway study resulting in the paper ‘CO2 abatement potential for offshore upstream installations’ describes how adopting cost-effective practices could provide a 29% reduction in the current CO2 emissions from offshore production on the NCS whilst also securing significant cost savings. The results took into account efforts already made to lower emissions such as reduced gas flaring activity.

“Despite the NCS being known as best in class when it comes to combating CO2 emissions and footprint, the work we have done with the CO2 abatement reveals that there is still cost effective potential left. The promising and inspiring results are making a profitable case for already available technologies for energy efficiency and storage, and the earlier the measures are implemented for a field production, the greater the cost savings. As around 75% of global oil production in 2040 is projected to come from new fields, it should be possible to reduce CO2 emissions dramatically on a global scale over the next quarter of a century,” adds Tørstad.

In order to ascertain the status of sustainability efforts across oil and gas producing regions and current field developments, DNV GL has also developed a map based on publicly available databases and literature. The map identifies regions and field developments with the most and least potential for improvement on governance and production efficiency. The results are presented in a traffic light system detailing economic, environmental and social performance criteria of resources and production in regions. The results of the benchmark are dynamic and can be used to identify areas for sustainability improvements as well as enable a wider basis for investments decisions.

Shell announced on Tuesday, September 6, 2016, that production has started from the Stones development in the Gulf of Mexico. Stones is expected to produce around 50,000 barrels of oil equivalent per day (boe/d) when fully ramped up at the end of 2017.

The host facility for the world’s deepest offshore oil and gas project is a floating production, storage and offloading (FPSO) vessel. It is the thirteenth FPSO in Shell’s global deep-water portfolio and produces through subsea infrastructure beneath 9,500 feet (2,900 meters) of water. Stones underscores Shell’s long-standing leadership in using FPSOs to safely and responsibly unlock energy resources from deep-water assets around the world.

“Stones is the latest example of our leadership, capability, and knowledge which are key to profitably developing our global deep-water resources,” said Andy Brown, Upstream Director, Royal Dutch Shell. “Our growing expertise in using such technologies in innovative ways will help us unlock more deep-water resources around the world.”

Stones, which is 100% owned and operated by Shell, is the company’s second producing field from the Lower Tertiary geologic frontier in the Gulf of Mexico, following the start-up of Perdido in 2010.

The project demonstrates Shell’s commitment to realizing significant cost savings through innovation. It features a more cost-effective well design, which requires fewer materials and lowers installation costs; this is expected to deliver up to $1 billion reduction in well costs once all the producers are completed.

The FPSO is also specially designed to operate safely during storms. In the event of a severe storm or hurricane, it can disconnect and sail away from the field. Once the weather event has passed, the vessel would return and safely resume production.

Shell’s global deep water business is a growth priority for the company and currently produces 600,000 boe/d. Deep-water production is expected to increase to more than 900,000 boe/d by the early 2020s from already discovered, established reservoirs. Three other Shell-operated projects are currently under construction or undergoing pre-production commissioning: Coulomb Phase 2 and Appomattox in the Gulf of Mexico and Malikai in Malaysia.

  • Stones, employs an innovative lazy wave riser configuration, consisting of a steel catenary riser with buoyancy added with an arch bend to decouple the FPSO’s dynamic motions and subsequently increase riser performance.
  • An ultra-deep-water mooring system maintains the FPSO’s location over the Stones field. 3D printing was used during the design phase to develop prototypes of the detachable system for the project to ensure safety and prevent schedule delays.
  • The development will start with two subsea production wells tied back to the FPSO vessel, followed later by six additional production wells. Multi-phase seafloor pumping is planned for a later phase to pump oil and gas from the seabed to the vessel, increasing recoverable volumes and production rates.

Semco Maritime has been awarded a contract on Atex Management Services including software supplied by SafeEx for inspection of approximately 30,000 pieces of equipment in Maersk Oil's Culzean project.

After a bidding round, it is official that Semco Maritime will be suppliers of a system based on the SafeEx Software for inspections in Maersk Oil's Culzean gas field. The software will be used to perform the initial Ex-inspections on a production platform, which consists of a residential platform, a process platform, a wellhead platform and a FSO operating in the field.

Though the system initially will be used for Ex-inspections, there is a further desire to use it for mechanical completion and other maintenance and inspection tasks. The system will be integrated to Maersk Oil’s ERP systems SAP and technical completion system PIM360.

9SafeEx tablet based inspection and maintenance software allows you to perform all routines in one procedureSafeEx’ tablet-based inspection and maintenance software allows you to perform all routines in one procedure.

- The advantage of the SafeEx Software is that the system provides a uniform way to make inspections that increases safety and save 30 to 60 percent on man-hours, says Market and Business Development Manager Erik Grønborg from Semco Maritime, who for years has designed and produced equipment for Maersk Oil.

All routines in one procedure

SafeEx’ tablet-based inspection and maintenance software allows you to perform all routines in one procedure. Technologically it is the leading solution on the market right now.

A standard rig or platform typically have 30 to 40 different checklists for inspections, but the SafeEx Software converts these checklist into electronic tasks. The tasks are conducted in guidance from the hand-held tablet using integrated layout drawings. This gives a significant reduction in the number of man-hours.

Each piece of equipment has a RFID chip installed, which is approved for Ex zone 1. This enables the software in the handheld device to create an electronic time-stamp and a full electronic audit trail. After each completion of an inspection, all information is instantly available online both off-shore on the unit and among the onshore management.

- Our mission with the tablet-based software solution has been to streamline work procedures of inspections, in order to make them faster, easier and more cost-effective in performance. In addition, there is the whole safety aspect in which our software provides a full overview of the maintenance condition, explains CEO Henrik Andersen from SafeEx.

The contract with Maersk Oil is one of the largest installation in terms of number of equipment that SafeEx has ever won. Besides the fact that the system will be used at Maersk Oil, the DNV GL-verified SafeEx Software is being used for inspections at among others Petronas, Statoil, Dong Energy, Seadrill, Noble, BW Offshore, Aker Solutions and Arla Foods.

One of the largest discoveries

The Maersk Oil operated Culzean project is located about 145 miles east of Aberdeen and is one of the largest gas discoveries in the UK North Sea.

The first gas from the project is expected in 2019 and it is expected to provide for around five percent of UK’s total gas consumption by 2020/21 with a peak production rate of 400 to 500 million standard cubic feet per day.

A simple, smart concept and increased drilling efficiency have shaved some NOK 200 million off the capital expenditures of this already resilient development project after the investment decision.

The development helps maximize production from the Fram area, in addition to boosting Troll C production and activities.

Fram C East is a long production well drilled from the existing Fram subsea template. Production will be tied back to Troll C, an important North Sea hub.

Gas will be transported to Kollsnes via Troll A, whereas oil will be piped to Mongstad for further processing.

Originally estimated at some NOK 800 million capital expenditures have now been reduced to some NOK 600 million thanks to a simple, smart well concept and significantly increased drilling efficiency.

“Fram C East is a small development project, but a key element of our plans to capture maximum value in the Fram area,” says Lars Høier, vice president operations, Troll and Fram.

“We are pleased to see that our targeted efforts to cut costs and improve profitability on the Norwegian continental shelf (NCS) have benefitted this development project. Fram C East has seen profitability rise from good to even better, and will see a positive cash flow as early as in 2016,” Høier adds.

Statoil has a long-standing record of infrastructure development on the NCS, which is key to the profitability of small-size development projects.

Last week Statoil submitted the Plan for Development and Operation of Byrding (north of Fram) together with another partnership. Production from this field, too, is tied back to the Troll C platform.

“Our strong position and role in several partnerships in the Troll / Fram area give us flexibility and possibilities to generate high value by taking an overall approach to the area, maximizing the use of the existing infrastructure. This represents good resource management, benefitting our partners, our owners, suppliers and society at large,” says Gunnar Nakken, senior vice president, Operations West.

Capital expenditures totaling some NOK 600 million, recoverable resources are estimated at 18.2 million barrels of oil and 1.6 billion sm3 of gas. Profitability is resilient with a low break-even.

15BOEMlogoBureau of Ocean Energy Management (BOEM) Director Abigail Ross Hopper announced that last week’s oil and gas Lease Sale 248 garnered $18,067,020 in high bids for 24 tracts covering 138,240 acres in the Western Gulf of Mexico Planning Area. A total of three offshore energy companies participated in 24 bids. The sum of all bids received totaled $18,067,020.

In this sale, BOEM offered 23.8 million acres in federal waters offshore Texas for oil and gas exploration and development.

“The Gulf of Mexico continues to be one of the most productive basins in the world and is an important part of our Nation’s domestic energy portfolio,” said Hopper. “Though this sale reflects today’s market conditions and industry’s current development strategy, the bidding confirms that there is continued interest in the deepwater areas of the Gulf”.

BOEM oversees 160 million acres on the Outer Continental Shelf in the Gulf of Mexico. Approximately 20 million acres (3,762 blocks) are leased for oil and gas development; and 4.3 million of those acres (883 blocks) are producing oil and natural gas.

The August 24 sale in New Orleans, Louisiana, was the first federal offshore oil and gas auction broadcast live on the internet, delivering pertinent bid information immediately to a much broader national and international audience. Through this approach, BOEM aims to promote greater government efficiency and transparency. A video of the livestream broadcast will be posted to the BOEM website.

Today’s auction is the eleventh Gulf of Mexico offshore sale and the final one for the Western Planning Area, under the Administration’s Outer Continental Shelf Oil and Gas Leasing Program for 2012-2017 (Five Year Program). This sale builds on the first ten sales in the current Five Year Program, which offered more than 60 million acres and netted nearly $3 billion for American taxpayers.

Sale 248 included approximately 4,399 blocks, located from nine to 250 nautical miles offshore, in water depths ranging from 16 to more than 10,975 feet (5 to 3,340 meters). As a result of offering this area for lease, BOEM estimates a range of economically recoverable hydrocarbons to be discovered and produced of 116 to 200 million barrels of oil and 538 to 938 billion cubic feet of natural gas.

The decision to hold this sale follows extensive environmental analysis, public comment and consideration of the best scientific information available. The terms of the sale include stipulations to protect biologically sensitive resources, mitigate potential adverse effects on protected species and avoid potential conflicts associated with oil and gas development in the region. The lease terms also include a range of incentives to encourage diligent development and ensure a fair return to taxpayers.

Following the sale, each bid will go through an extensive 90-day evaluation process to ensure the public receives fair market value before a lease is awarded.

Statistics for Western Sale 248 are available here.

Gullfaks Rimfaksdalen (GRD) was scheduled for start-up on Christmas Eve this year, but the project has worked faster and now the field is on stream – at lower costs than planned.

The project delivered is more than NOK 1 billion below the estimate of the plan for development and operation (PDO), reducing costs from NOK 4.8 billion to around NOK 3.7 billion.

"I am pleased to see that the project starts up four months ahead of plan, demonstrating good and efficient project management," says Torger Rød, senior vice president for project development in Statoil.

Over time we have focused on reducing costs and raising the profitability of our projects to ensure long-term activity and value creation on the Norwegian continental shelf (NCS). Based on a smart concept using standard solutions and existing infrastructure, Gullfaks Rimfaksdalen strongly proves that we are on the right track to succeed on this work," continues Rød.

Recoverable reserves are approximately 80 million barrels of oil equivalent, mostly gas. The licensees are Statoil (operator) (51%), Petoro (30%) and OMV (19%).

"The volumes from Gullfaks Rimfaksdalen help us reach our ambition of maintaining production and a high activity level on the NCS beyond 2030. We have a well-developed infrastructure and we will keep realizing opportunities in the North Sea," says Arne Sigve Nylund, executive vice president for Development and Production Norway.

"This development leads to more production, improved value creation and higher activity level on Gullfaks, and also throughout the value chain related to the field," continues Nylund.

The Gullfaks Rimfaksdalen development consists of a standard subsea template with two simple gas production wells, and possibilities for tie-in of two more wells. The well stream is connected to the existing pipeline leading to the Gullfaks A platform.

Gas and condensate are transported in existing pipelines to the processing plant at Kårstø north of Stavanger for processing, and from there the gas is exported to markets on the European continent. Gullfaks Rimfaksdalen is one of Statoil’s fast-track projects, aiming to realize resources quickly and inexpensively, for example by using existing infrastructure while it is still available.

The intention of the MoU is to evaluate joint participation in future tenders for exploration areas and to increase upstream collaboration in producing fields in the Santos and Campos offshore basins.

The agreement also sets out a potential framework for cooperation on value creating opportunities in the gas value chain.

The agreement was signed by Petrobras’ president and CEO Pedro Parente and Statoil’s CEO Eldar Sætre during the ONS 2016 conference in Stavanger.

It follows the agreement in July 2016 whereby Statoil acquired Petrobras’ 66% operated interest of the BM-S-8 offshore license in the Santos basin, subject to government approval. "This MoU reflects our long-term commitment to Brazil and is a result of our strong and long-standing relationship with Petrobras. Collaboration with partners like Petrobras, a company well-known for its technical expertise and profound knowledge about one of our core strategic areas, represents an excellent opportunity for us. We hope that this will result in significant value creation potential for both parties”, says Statoil CEO, Eldar Sætre.

Petrobras and Statoil through this agreement will continue their exploration strategic alliance, with the intent to define opportunities in the pre-salt polygon of the Santos and Campos basin. The companies aim to capture value through application of technology and simplification of operational activities. Currently, Petrobras and Statoil are partners in 13 blocks in either exploration or production; 10 in Brazil and three abroad.

"We are moving into a strategic partnership that will be beneficial for both companies. Statoil has very high levels of oil recovery in their producing fields, for example, and we will have access to this experience and know-how through a partner, with obvious benefits for both sides", says Petrobras CEO, Pedro Parente.

The agreement has a horizon of two years, and the joint activities undertaken will depend on negotiations following the signing of the document.

7Horne and Wren Claxton1Claxton, an Acteon company, has completed its involvement in the abandonment of two wells on the Horne and Wren Platform in the Southern North Sea.

Completed within 18 days in July 2016, Claxton was responsible for the 5.1/2” tubing cut verification, tubing recovery, sub-mudline abrasive conductor severance, conductor cut verification and the subsequent multi-string recovery from both wells.

Rob Horton, project engineer, Claxton, said: “The multi-string severance was performed from a jack-up lift barge (JULB) for this project, allowing significant cost savings for the client against the use of a rig.

“The Horne and Wren platform has a small 8m x 8m weather deck footprint, creating a space challenge which we managed to overcome. As well as using our latest evolution of the ‘SABRE’ abrasive cutting system, this project also required a full, bespoke, light weight work package. This included a hydraulic proving system and a utility crane to ensure self-sufficiency in handling our equipment.

“Proving of tubing and conductor cuts were completed with the same system, enabling us to reduce equipment, time and money for the client. Equipment was located on the JULB with services run to the platform for the tubing recovery and multi-string severance and subsequent casing retrieval.

“We also developed a bespoke tubing laydown frame that allowed the quick and safe laydown of the severed tubing in a controlled manner.”

Claxton can overcome issues in engineering bespoke designs to accommodate all platforms and environments. Rigless platform well abandonment is just one of the many services Claxton can offer to reduce the costs of decommissioning projects. Learn more about Claxton’s decommissioning services.

16BSEE inspectionLast week, U.S. Department of the Interior Deputy Assistant Secretary for Land and Minerals Management Amanda Leiter and Bureau of Safety and Environmental Enforcement Director Brian Salerno announced final regulations to ensure that safety and maintenance requirements are current for offshore oil and gas production technologies. The Production Safety Systems Rule utilizes industry standards and best practices for the use of offshore safety equipment and systems, while also prescribing maintenance, testing and reporting requirements for specific production and subsurface safety devices.

“The Department has a responsibility to update its regulations to keep pace with advancing technology and ensure the safest possible offshore oil and gas operations,” said Deputy Assistant Secretary Leiter. “The regulations issued today reflect the industry’s shift to deeper waters and adoption of more sophisticated technology. The Administration is committed to safe and environmentally responsible operations utilizing the most effective technology available.”

These final regulations revise and update the Code of Federal Regulations section that addresses oil and gas production safety systems. The section was first published in 1988. The rule published today incorporates many Bureau of Safety and Environmental Enforcement (BSEE) policies that have been developed over the past 28 years. In 1988, many of the technologies currently in use did not exist. The final rule addresses a number of safety issues including production safety systems, subsurface safety devices, safety device testing, and production processing systems.

“By updating the requirements for these critical safety systems, we are meeting our commitment to promote the highest level of protection for both offshore workers and the environment,” explained BSEE Director Salerno. “The rulemaking process allowed us to develop the most effective and timely revisions by incorporating input from our partner federal agencies, industry, and research organizations.”

The revised requirements have been sent to the Federal Register and will go into effect 60 days following the publication of the final rule. BSEE has deferred the compliance dates for certain provisions of the final rule. These provisions and deferred compliance dates can be found in the Federal Register notice.
