Seabox AS Acquired by NOV
National Oilwell Varco (NOV) has acquired 97% of the shares in Seabox for an undisclosed amount from a group of shareholders led by HitecVision.
Seabox is a Norwegian subsea technology company founded around the patented SWIT technology (Subsea Water Intake & Treatment). The technology enables treatment of raw seawater on the seabed (as opposed to on a platform) for injection into oil & gas wells for pressure support and increased oil recovery.
The company was established in 2004, and has, through a series of Joint Industry Projects backed by the Norwegian Research Council and by potential end-users such as ExxonMobil, ConocoPhillips, Shell, Total, Statoil, GDF Suez and others, developed the technology to a level where it is now ready for commercialization. Seabox has 12 employees.
Helge Lunde, CEO of Seabox comments: “We are very excited to team up with NOV’s global organization, which will significantly increase our reach and chances of succeeding in commercializing our technology. We are both proud and happy for their recognition of our efforts and technical solutions, and their commitment to backing us through the coming growth phase. We are convinced that our growth will be faster and stronger together with NOV.”
Michael Hjorth, President of Flexibles and Subsea Production Systems, comments: “NOV has a strong history and presence in Norway, where some of our key technologies for drilling, turret mooring and deck cranes have been developed, and to a large degree also manufactured. When it comes to subsea, which is an area where NOV wants to develop and expand, Norway is pretty much the “Silicon Valley” of the industry, so it is natural for us to search for new technologies and ideas here. In Seabox we have found what we deem to be innovative yet robust technical solutions, which offer more cost effective solutions but more importantly will offer the oil & gas companies greater flexibility in optimizing their reservoir drainage and field profitability. This is a huge market, with some 250 million barrels of seawater injected daily world-wide, which is almost three times the daily oil production. We are excited to explore these market opportunities together with Seabox.”
Chevron strikes oil at Guadalupe, Gulf of Mexico
Chevron Corporation today announced a new oil discovery at the Guadalupe prospect in the deepwater U.S. Gulf of Mexico.
The Keathley Canyon Block 10 Well No. 1 encountered significant oil pay in the Lower Tertiary Wilcox Sands. The well is located approximately 180 miles off the Louisiana coast in 3,992 feet of water and was drilled to a depth of 30,173 feet.
“The discovery further demonstrates Chevron’s exploration capabilities,” said George Kirkland, vice chairman and executive vice president, Upstream, Chevron Corporation. “Guadalupe builds on our already strong position in the deepwater U.S. Gulf of Mexico, a core focus area where we expect significant production growth over the next two years.”
“The Guadalupe discovery adds momentum to our growing business in North America,” said Jay Johnson, senior vice president, Upstream, Chevron Corporation. “Our deepwater exploration and appraisal program continues to unlock important resources in the Gulf of Mexico.”
“The company expects additional Gulf of Mexico production from the Tubular Bells and Jack/St. Malo projects by the end of the year.”
“Chevron subsidiaries are among the top producers and leaseholders in the Gulf of Mexico, averaging net daily production of 143,000 barrels of crude oil, 347 million cubic feet of natural gas, and 15,000 barrels of natural gas liquids during 2013,” said Jeff Shellebarger, president, Chevron North America Exploration and Production Company. “The company expects additional Gulf of Mexico production from the Tubular Bells and Jack/St. Malo projects by the end of the year.”
Chevron subsidiary Chevron U.S.A., Inc. began drilling the Guadalupe well in June 2014. More tests are being conducted on the discovery well and additional appraisal wells will be needed to determine the extent of the resource.

Williams Partners: Gulfstar One spar nears completion (VIDEO)
Williams Partners L.P. reported key construction milestones and progress on a tieback expansion as its proprietary Gulfstar FPS™ (Floating Production System) nears completion in the eastern deepwater Gulf of Mexico. The Gulfstar One project is the first spar-based floating production system with major components built entirely in the United States.
“Williams Partners’ made-in-America Gulfstar One is 21,500 tons of proof that American engineering and construction are alive and well. The hull of the floating production system was towed out and positioned in the deepwater Gulf of Mexico before the topside platform was installed in March 2014.” the company said in a press release.
After mooring the floating spar to the ocean floor in February, crews in March lifted and installed Gulfstar’s three-level topside structure. The floating production system is moored 135 miles southeast of New Orleans in about 4,000 feet of water. It will serve as a hub that aggregates production and then combines production handling services with oil and gas export pipeline services, which feed Williams’ downstream oil and gas gathering and processing services.
Once operational, the Gulfstar’s base design will produce up to 60,000 barrels of oil per day and 135 million standard cubic feet of gas per day with additional tieback capacity. With hook-up and commissioning activities currently underway, Gulfstar is on schedule to start serving anchor customers in the third quarter of 2014 and Gunflint in 2016.
In addition to previously announced anchor commitments, Gulfstar in January executed agreements with Gunflint field owners Noble Energy, Inc., Ecopetrol America Inc., Marathon Oil Company and Samson Offshore, LLC. The Gunflint tieback is designed and engineered with modifications expected to be completed after the base Gulfstar project is completed.
“Landing this Gunflint tieback before first oil is received from the anchor tenants demonstrates the promise of the Gulfstar model for producers, both economically and technically,” said Rory Miller, senior vice president of Williams’ Atlantic-Gulf operating area. “As a midstream company, Williams is focused on infrastructure solutions of this nature that connect the best supplies with highest-value markets. Gulfstar is one of approximately $4.5 billion in large-scale projects we expect to bring into service in 2014 and 2015.”
Major components of the Gulfstar were built entirely in the United States, creating approximately 1,000 domestic jobs and allowing quick parts replacement and reduced platform downtime. Gulf Marine Fabricators built the hull in Aransas Pass, Texas and Gulf Island Fabrication, Inc. constructed the topsides in Houma, La.
“Gulfstar provides a complete ‘floating production system to market clearing point’ solution for producers in the Gulf for their oil, gas and liquids production, designed specifically to maximize their net present value and minimize risk,” said Mark Cizek, Gulfstar Project Director. “The ‘design one, build many’ construction concept allows for standardized design options and enhanced safety and reliability of each unit. The repeatable concept also increases speed to market.”
Williams Partners developed the Gulfstar One project and it has a 51 percent ownership interest. Marubeni Corporation has a 49 percent interest in the Gulfstar One project.
BP Brings Two Rigs to Deepwater Gulf of Mexico
BP has added two drilling rigs to the deepwater Gulf of Mexico, bringing its fleet to a company record nine rigs as it continues to develop its strong portfolio of assets in the key U.S. offshore basin.
One of the rigs is a new ultra-deepwater drillship known as the West Auriga that is under long-term contract to BP from Seadrill Ltd, a leading international offshore drilling contractor. The vessel, capable of operating in up to 12,000 feet of water, has begun development drilling work at BP’s Thunder Horse field.
The other is a reconstructed drilling rig on BP’s Mad Dog oil and gas production platform. It replaces the original rig on the platform that was badly damaged and left inoperable by Hurricane Ike in 2008. With the new, state-of-the art rig, the platform recently resumed development drilling at the massive Mad Dog field complex.
“The addition of these two rigs reflects the vital importance of the deepwater Gulf of Mexico to the future of BP,” said Richard Morrison, Regional President of BP’s Gulf of Mexico business. “It also clearly demonstrates BP’s commitment to the American economy and to U.S. energy security.”
BP currently anticipates investing on average at least $4 billion in the Gulf of Mexico each year for the next decade. The company plans to concentrate future activity and investment in the Gulf on growth opportunities around its four major operated production hubs – Thunder Horse, Na Kika, Atlantis and Mad Dog – and three non-operated production hubs – Mars, Ursa and Great White – in the deepwater, as well as on significant exploration and appraisal opportunities in the Paleogene and elsewhere.
BP is also advancing a strong pipeline of future development projects in the deepwater Gulf. In April, the company started up the Atlantis North expansion, the first of seven additional wells to be tied back to the existing Atlantis platform. At Na Kika, another field expansion is planned, following the successful startup last year of the Galapagos development, a subsea tieback to the Na Kika production facility. BP is also pursuing plans for a second phase of the Mad Dog field.

Ulstein Presents Benefits of Its SX121 Design
Advancement in technology is permitting the offshore oil and gas industry to move into progressively deeper and colder waters in remote locations. ULSTEIN supports this development by providing products and solutions that contribute to safer, smarter and greener operations.
A case in point is the versatile and flexible OCV/subsea vessel design SX121, which ULSTEIN is currently building customized versions of for GC Rieber Shipping and Island Offshore. The design can be tailored for a multitude of offshore construction and subsea operations in deep and ultra-deep waters both below and above the Arctic Circle.
Deepwater and ultra-deepwater projects occur outside of the continental shelf at water depths between 400 and 1,500 metres and depths greater than 1,500 metres respectively. Deep waters mean remote locations, harsh weather conditions and sensitive ecosystems. This type of environment requires vessels that are reliable and safe, cost-efficient and environmentally sound.
“We aim to develop ships that can operate reliably, safely and efficiently in harsh conditions with as small an environmental footprint as possible. The robust configuration, system integration and X-BOW® hull line of the SX121 ensure safety and comfort for the crew, an increased operational window and significantly reduced environmental impact,” says sales manager in Ulstein Design & Solutions, Lars Ståle Skoge.
Currently, there are four sailing SX121 vessels designed and built by ULSTEIN. The vessels, which operate in different segments such as offshore construction, riserless well intervention and inspection/maintenance/repair, have received very good feedback.
Gordon L. Wilkinson in Veolia ES said the following about ‘Viking Poseidon’’s work in the Gulf of Mexico: “She is the Queen of the Gulf.”
At the end of 2012 shipowner Island Offshore, together with their American partner Edison Chouest Offshore, ordered another SX121 vessel from ULSTEIN currently under construction at Ulstein Verft. “We’ve received very good feedback on our two operating vessels of this design, ‘Island Constructor’ and ‘Island Intervention’,” says Technical Manager in Island Offshore, Trond Hauge. “I’m confident that this type of vessel is a safe and comfortable platform for the performance of advanced work in the years to come.”
Optimized for heavier installations
“The SX121 is a compact vessel that can perform deepwater and ultra-deepwater operations for which currently larger vessels are frequently used, thus providing the customer with a more cost-efficient solution,” says Håvard Stave, Sales Manager in Ulstein Verft.
“The typical SX121 vessel operates at depths down to 3,000 metres, which comprises most current oil & gas activities. The need to deploy heavier equipment in deep waters such as offshore Brazil and Africa and in the Gulf of Mexico, has spurred market interest in OCV vessels with a 400-tonne crane, which we’ve now incorporated in the SX121 design.”
ULSTEIN has drawn on experiences from its latest SX121 projects, and optimized the utilization of the hull with regards to work from deck as well as crane construction work, resulting in an even more versatile OCV/subsea vessel.
The robust platform is optimized for efficient operations in deep waters with a crane capacity of up to 400 tonnes and a substantial remaining deck loading capacity, and it can be configured for a variety of mission equipment. There is a large deck area of 1,750 m2, and the area around the main moon pool is reinforced in order to sustain a VLS or module handling system. The ROV installation is designed and chosen for operations in significant wave heights of 4.5 metres or more. Two heavy-duty work ROVs are situated in the enclosed hangar, one to be deployed from the starboard side, the other through a dedicated moon pool.
A reliable vessel is key for cost-efficiency, as down-time and aborting on-going operations are costly affairs, particularly when operating far from shore.
The SX121 vessel meets the highest standard for position keeping, DYNPOS-AUTRO, with redundancy on all major components. Featuring the ‘Operation+’ concept, an increase in redundancy in AUTR operations if a single major failure occurs, the vessel will still maintain system redundancy throughout the most critical areas. The typical configuration is diesel electric propulsion powered by six identical medium speed main generator sets. The switchboard system, propellers and diesel motors can be configured in groups of two, three or four. If a major failure occurs, the vessel will only lose one third of its power and propulsion. The combination of system architecture and power stations, three side thrusters and three main thrusters, ensures that the operation can be safely completed using two thirds of its capacity.
Smart and safe
In order to optimize capacities and performance of the vessel, the freeboard has been increased by one metre compared with the previously built vessels of this design. This increase also improves safety and ensures a dry work deck. In addition, the helideck has been moved further back in order to increase the weather window for helicopter landings.
The vessel’s X-BOW provides good motion characteristics for safe operations. It also reduces the vessel’s environmental footprint through lower fuel consumption and reduced emissions. With optimized resolution of the power generation plant, the vessel will have high fuel efficiency in all operational modes.
The vessel accommodates a crew of 130 and complies with all international requirements for comfort and safety.
Gulf of Mexico: Halliburton’s ESTMZ System Used on Chevron’s Three Wells
Halliburton announced today the successful completion of three wells in the Deep Water Gulf of Mexico utilizing Halliburton’s Enhanced Single-Trip Multizone (ESTMZ™) FracPac™ System.
ESTMZ™ downhole tool system enables the operator to stimulate and gravel pack multiple production zones in a single trip. Designed for use in Dee Water and Ultra-Deep Water offshore completions, the ESTMZ™ system allows the highest treating rate with the greatest volume of proppant in the industry.
Halliburton developed the multi-zone completion technology in collaboration with Chevron U.S.A. Inc. The two companies conducted numerous system integration tests and two field trials to prove the technology.
The time savings realized for each of the three Chevron-operated wells completed with the ESTMZ™ system averaged 18 days, equating to approximately $22 million.
“ESTMZ™ system allows more reservoir to be stimulated in a shorter amount of time, thus increasing efficiency, reliability and production, which is key to the success of the Lower Tertiary,” said Ron Shuman, Senior Vice President of Halliburton’s Southern and Gulf of Mexico regions.
“In addition, this system allows us to deliver a very aggressive stimulation with rates up to 45 barrels per minute and volumes greater than 400,000 pounds of 16/30 high strength proppant. We deliver this with weighted frac fluid and 10,000 horsepower per interval for up to five intervals, providing a total cumulative proppant volume of greater than two million pounds per well with one service tool. Having to make multiple runs in and out of the wellbore equates to a large expense for operators. The ‘single trip’ element of this system provides significant time savings with improved reliability and better asset optimization,” Shuman concluded.
Providing wellbore assurance through various critical operations such as wellbore cleanout, completion services, pumping and fluids also contributed to the success of these three wells. This integrated approach in planning and execution mitigated risks while promoting efficiency and providing an optimal conduit for the reservoir to flow.
The proven reliability of Halliburton’s ESTMZ™ tool system and the continual evolution of these smart technologies are critical to the changing landscape in the Gulf of Mexico. To date, Halliburton has successfully deployed nearly 20 ESTMZ™ systems around the globe including the Asia Pacific region.
