New technologies, keen strategies and a sharpened focus keep offshore operators determined and decisive. Activity is picking up, and these key players are focused on increasing profits and production.
Offshore the U.K., the production forecast is looking more positive. “Development activity in the U.K. offshore sector is expected to improve after historical lows in the past few years,” according to a March 2019 GlobalData report. “There are 16 planned greenfield projects with identified development plans and 29 announced greenfield projects forecast to start production between 2019 and 2025. These are estimated to cost around $6.7 billion and $11.4 billion, respectively.”
In other areas, such as offshore Argentina, exploration is the main focus for operators. “Any big discovery in Argentina’s offshore frontier area will be a great prize for companies looking into building up a portfolio for future development. However, such long-term strategies will compete with a current preference for exploration in offshore areas with more seismic and well information available and where logistics to commercialize production is already known,” GlobalData said in a September 2018 report.
Moreover, E&P activity has heightened drastically in the Gulf of Mexico in the last year. Wood Mackenzie recently reported that 2019 “is shaping up to be a good one in the U.S. Gulf of Mexico, with the first increase in drilling in four years, first-ever production from a Jurassic play, key new project sanctions and an uptick in M&A [mergers and acquisitions] all in the cards.” Wood Mackenzie expects exploration activity to increase 30% this year. “Shell and Chevron will lead the way, but the actual growth in exploration will come from new entrants—Kosmos Energy, Equinor, Total, Murphy and Fieldwood,” the report stated.
The following is a sampling of offshore operators, their recent production updates and strategies moving forward.

As of press time in late March/early April, first-quarter 2019 results had not been released. If available, updates have been posted beneath each company profile.
Aker BP ASA
Aker BP is the operator for Valhall, Ula, Ivar Aasen, Alvheim and Skarv offshore field centers. According to the company, it is one of the biggest independent listed oil and gas companies in Europe, measured by production. The company’s net production in 2018 was 155,700 boe/d, and total production volume was 56.8 MMboe. In the fourth quarter of 2018 production volumes increased due to improved efficiency and new wells, according to the company.
According to the company’s fourth-quarter 2018 report released on Feb. 6, “Aker BP continued its positive development and strong growth in 2018. Total income increased by 46% from 2017 and all major field development projects progressed as planned. Reserve replacement was above 100%, and the company continued to grow its resource base through acquisitions and exploration success.”
In the development arena, Aker BP said Phase 1 of the Johan Sverdrup development project is progressing steadily toward planned production start in November 2019. “Johan Sverdrup is a major discovery and ranks among the five largest oil fields on the Norwegian Continental Shelf [NCS],” the company said on its website. “The development of the field will be one of the key industrial projects in Norway over the next 50 years.”
The company is an active explorer on the NCS. “In recent years about two-thirds of Aker BP’s exploration budget has been invested in the mature areas in the North Sea, where the infrastructure is good and the discovery rate is still high. The remaining resources have been invested primarily in the Barents Sea and in the more immature areas in the North Sea,” the company said.
Aker BP reported fourth-quarter 2018 production of 58,400 boe/d for the Alvheim area, 23,300 boe/d for Ivar Aasen, 23,500 boe/d for Skarv, 8,400 boe/d for the Ula area and 39,600 boe/d for the Valhall area, according to the report.
In the Alvheim area, the Skogul project is progressing according to plan and production start is scheduled for the first quarter of 2020, the report stated. In the first quarter of 2018, an oil discovery was made in the Frosk prospect near the Bøyla Field, and a new well was scheduled to be drilled in the first half of 2019. Aker BP will continue its exploration of the Frosk area this year.
In the Valhall area, drilling from the IP platform continued with the G22 well coming onstream during the fourth quarter of 2018. The G11 well was subsequently drilled and completed using the Fishbones technology in one section of the well. Test production began in February.
In the Ula area, development of the field is in its final stages. Drilling operations were completed in the fourth quarter last year. As of Feb. 6, Aker BP is performing the final preparations to start production, which is expected during the first half of the year, the report stated. There is the possibility the company will add a new platform at Ula in mid-2020.
Additionally, “Aker BP considers the resource potential in the Ula area to be significant, both from increased oil recovery in the Ula and Tambar fields, from potential tiebacks of other discoveries including the newly acquired King Lear discovery, and from exploration opportunities,” according to the report.
In the Skarv area, production start for the Ærfugl development is planned for the fourth quarter of 2020.

BHP, formerly known as BHP Billiton, has operating assets in the Shenzi, Neptune, Atlantis and Mad Dog fields in the Gulf of Mexico (GoM) as well as in several fields offshore Australia. Other offshore production operations are located in the Greater Angostura Field offshore Trinidad and Tobago. Petroleum exploration expenditure for the second half of 2018 was $316 million, and activity for the period was largely focused in the GoM and Trinidad and Tobago, according to BHP’s second-half 2018 results report released Feb. 19. This year a $750 million exploration and appraisal program is being executed.
In the U.S. GoM, “Samurai-2 and Samurai-2 ST01 drilling has delineated the accumulation of oil,” the report stated. “Further appraisal and development planning at Samurai is in progress. In the southern portion of the Wildling sub-basin, we continue to assess the potential resource, with further appraisal drilling now expected in the 2020 financial year.”
In the Western U.S. GoM, an ocean-bottom node seismic acquisition was completed in early January 2019 and processed data are expected to be delivered during March 2020. “This is the world’s first deepwater exploration ocean-bottom node seismic acquisition,” according to the company.
In addition, BHP spudded the Trion-2DEL appraisal well in the GoM in November 2018 and encountered oil in line with expectations. “This was followed by a planned downdip geologic sidetrack, which encountered oil and water, as predicted, further appraising the field and delineating the resource,” the report stated. “Following the recent encouraging results in the Trion Block, an additional appraisal well (3DEL) to further delineate the scale and characterization of the resource is expected to be drilled in the second half of 2019.”
Looking ahead, other major projects include the development of the Atlantis Phase 3 project in the deepwater GoM.
Offshore Trinidad and Tobago, the company encountered hydrocarbons at the Bongos-2 exploration well in the first half of 2019, and Phase 3 of BHP’s deepwater exploration drilling campaign will start in the second half of the year, according to the report. Phase 3 will test three wells on three prospects in the northern license area.
Offshore Eastern Canada, BHP was the successful bidder in October 2018 for licenses in the Orphan Basin, and the company has begun working with the Canada-Newfoundland and Labrador Offshore Petroleum Board to meet all regulatory requirements for the exploration phase. The licenses became effective in January.
April 17 update from company: BHP Operational Review for the nine months ended 31 March 2019
BP has offshore operations and development projects in the Gulf of Mexico (GoM) and offshore Trinidad and Tobago, the U.K., Egypt and Australia.
As of February, BP had already completed three major upstream project startups this year: Constellation in the U.S. GoM, the second stage of the West Nile Delta development offshore Egypt and gas production at Angelin offshore Trinidad.
In the last few years, BP has been very active in West Africa, accessing about 80,000 sq km (30,888 sq miles) of acreage with resource potential of 8 Bboe.
“In drilling, over 70% of our offshore wells are now top quartile—from 25% just five years ago. And during the same period, our percentage of nonproductive time for completions has reduced by around 30%,” Bernard Looney, BP’s Upstream chief executive, said during an investor day presentation in December 2018. “Mad Dog 2 [in the GoM] is a great example of our drilling performance. …Three of our last four wells are the best ever drilled.”
Over the next few years, the company plans on wrapping up construction projects for Angelin offshore Trinidad, Constellation in the GoM, Culzean in the North Sea and West Nile Delta-Raven offshore Egypt this year; the KG D6 R-Series in the Bay of Bengal, Alligin and Vorlich in the North Sea, and Zinia 2 offshore Angola in 2020; and Mad Dog Phase 2 in the GoM, KG D6 Satellites and Manuel in the GoM in 2021.
In addition, the company has had a strong focus on improving efficiencies via new technology developments and upgrades. “In Trinidad we are using the latest digital modeling technology—think 3-D visualization of our offshore facilities. This allows us to complete detailed activity planning on our normally unmanned installations without having to go offshore, improving safety through reduced visits and saving $450,000 so far,” Looney said.
“In the Gulf of Mexico, our project teams have been using our latest agile ways of working and challenging themselves to bring our new subsea tiebacks online quicker. They are making good progress with seven tiebacks either in execute or operate with an average 10-month improvement in cycle time.”
He also noted that the application of seismic techniques, like ocean-bottom nodes, full waveform inversion and new ways of working at Thunder Horse, has unlocked an additional 1 Bbbl of oil in place (gross). “We now see the potential for the GoM to run at around 400,000 barrels of oil equivalent per day through the middle of the next decade,” he said.

Chevron, through its subsidiaries and affiliates, has offshore projects located in the deepwater U.S. Gulf of Mexico (GoM) as well as offshore Western Australia, New Zealand, South America, the U.K., West Africa and in the Gulf of Thailand.
During 2018, net daily production in the GoM averaged 186,000 bbl of crude oil, 3.3 MMcm (117 MMcf) of natural gas and 13,000 bbl of NGL, according to the company’s 2018 annual report supplement. As of early 2019, Chevron has an interest in 218 leases in the GoM. At year-end 2018, the company was the second largest leaseholder in the GoM.
Chevron’s signature deepwater project in the GoM is Jack/St. Malo, which is located about 451 km (280 miles) south of New Orleans. The project’s development phases progressed in 2018; Stage 2 was accomplished with all four wells on production and Stage 3 advanced, as two of the three planned wells were completed. Stage 4 includes water injection at the St. Malo Field and is expected to reach a final investment decision in the third quarter of 2019. Total daily production from the Jack and St. Malo fields averaged 139,000 bbl of liquids (71,000 net) and 594,654 cu. m (21 MMcf) of natural gas (11 million net) last year, according to the 2018 annual report supplement.
Also in the GoM, the Chevron-operated Big Foot deepwater project, located 362 km (225 miles) south of New Orleans, achieved first oil in November 2018 with ramp-up expected to continue during 2019. The field is estimated to contain total recoverable resources in excess of 200 MMboe, according to the company.
At the Tahiti Field, 2018 net daily production averaged 51,000 bbl of crude oil, 622,971 cu. m (22 MMcf) of natural gas and 3,000 bbl of NGL. The Tahiti Vertical Expansion Project is developing shallower reservoirs and achieved first oil from three wells in June 2018, and the fourth well was scheduled to come online in the second quarter of 2019.
Chevron also operates the Anchor Field located in the Green Canyon area off the coast of Louisiana. FEED activities commenced in 2018. The planned facility has a design capacity of 75,000 bbl/d of crude oil and 792,872 cu. m/d (28 MMcf/d) of natural gas, according to the 2018 annual report supplement. The total potentially recoverable oil-equivalent resources for Anchor are estimated to exceed 450 MMbbl.
In January 2018, Chevron announced a significant oil discovery at the Ballymore prospect in the Mississippi Canyon area in the deepwater GoM. The initial Ballymore well reached total measured depth of 8,898 m (29,194 ft) and encountered more than 204 m (670 ft) net oil pay with excellent reservoir and fluid characteristics, according to the company.
Offshore Western Australia, the Jansz-Io gas field is part of the Chevron-operated Gorgon project. In March 2019, Chevron contracted Aker Solutions to support delivery of a subsea compression system for the Jansz-Io with the aim of recovering gas more cost-effectively and with a smaller environmental footprint, according to news reports.
Jeff Schmoll, Chevron Australia’s general manager for major capital projects, said in March that “the Jansz-Io compression project will prolong the life of Gorgon’s Jansz-Io fields and was part of the original development plan for the project,” according to a miningweekly.com report.
Offshore Brazil, Chevron won six deepwater blocks in the presalt trend within the Campos and Santos basins in 2018. The six new blocks in the Brazil presalt cover 470,000 net acres.
On April 12 Chevron Corp. entered into a definitive agreement with Anadarko Petroleum Corp. to acquire all of the outstanding shares of Anadarko. The total enterprise value of the transaction is $50 billion, according to a press release. The transaction is expected to close in the second half of the year.

Eni’s primary offshore operations are located off the coast of Africa, Indonesia, Mexico and Norway, though the company has interests in other offshore areas.
Offshore Algeria, Eni, Sonatrach and Total signed two agreements that include an exclusive partnership for offshore exploration in Algeria in a virtually unexplored geological province.
In Egypt, Eni operates through its subsidiary leoc. In March the company announced a new gas discovery in the Nour prospect in the Eastern Egyptian Mediterranean offshore Egypt, a press release stated. Eni is the operator (40% stake), with BP (25%), Mubadala Petroleum (20%) and Tharwa Petroleum Co. (15%).
Throughout 2018 and again in March of this year, Eni announced several new oil discoveries offshore Angola. “Agogo is the third discovery of commercial nature since the Block 15/06 Consortium decided to launch a new exploration campaign in 2018, leading to the discoveries of Kalimba and Afoxé,” according to a March 2019 press release. “The [latest] discovery opens new opportunities for oil exploration below salt diapirs in the northwest part of the prolific Block 15/06, thus creating new chances for unlocking additional potential value.”
Eni is the operator of Block 15/06 (36.8% interest), along with partners Sonangol P&P (36.8%) and SSI Fifteen Ltd. (26.3%). According to the release, the companies plan on appraising the discovery and starting the studies to fast track the block’s development.
Offshore Ghana, Eni started gas production in July 2018 from the Sankofa Field in the Offshore Cape Three Points Integrated Oil and Gas Project. “The field will provide 180 million standard cubic feet per day [5.1 MMcm/d] for at least 15 years, enough to convert to gas half of Ghana’s power generation capacity,” a press release stated.
In December 2018, Eni announced a Merakes East gas discovery in the East Sepinggan Block offshore Indonesia, a press release stated. Eni is the operator of the East Sepinggan contract area through its subsidiary Eni East Sepinggan Ltd. (85% interest) with PT Pertamina Hulu Energi East Sepinggan (15%).
Offshore Mexico, Eni’s wholly owned subsidiary Eni Mexico S. de R. L. de C. V. holds rights in six E&P blocks in the Sureste Basin, all as the operator.

In addition to its name change of Statoil to Equinor in May 2018, the Norwegian multinational energy company has had quite an eventful 2018 and 2019.
In April 2018, in partnership with Total, the company acquired Cobalt International Energy’s 60% operated interest in the North Platte discovery in the U.S. Gulf of Mexico for $339 million.
In Brazil, Equinor has interests in the BM-S-8 and Carcará North in the presalt area of the Santos Basin as well as in the BM-C-33 in the Campos Basin, containing the Pão de Açúcar discovery. In June 2018, Equinor deepened its position in Brazil’s presalt area with 28% interest in the Uirapuru production-sharing contract in the Santos Basin.
In March 2018, the company acquired 50% interest in two offshore wind development projects offshore Poland.
On the Norwegian Continental Shelf (NCS), Equinor was awarded 31 new exploration licenses early last year.
In November 2018, Equinor began construction of the Johan Castberg vessel at Kværner’s yard at Stord. “Johan Castberg is the next major development on the Norwegian Continental Shelf and will open a new area in the Barents Sea for Equinor. Johan Castberg’s development will have ripple effects equivalent to 47,000 man-years in Norway during the development phase,” said Anders Opedal, Equinor’s executive vice president for technology, projects and drilling, in a press release.
In December 2018, Equinor (operator) and partners began production at the deepwater Aasta Hansteen Field on the NCS. The Aasta Hansteen is the first deepwater development on the NCS and the world’s largest single-point articulated riser platform, according to a press release.
Earlier this year, Equinor and its partners, Petoro, Exxon Mobil and Total, have proven gas and condensate in the Norwegian Sea Ragnfrid North (6406/2-9 S) exploration well. Recoverable resources are estimated at 6 MMboe to 25 MMboe, a January press release stated.
In March Equinor received approval for extending the life of eight installations on the NCS: Gullfaks A, B and C (2036), Oseberg East (2031), Snorre A and B (2040), Norne (2036) and Åsgard A (2030), a press release stated. Equinor plans to extend the life of more than 20 NCS installations in total and expects to apply for extending the life of all older and relevant installations by 2031.
The company also has been busy offshore the U.K. In March 2018, the company became the operator of the Martin Linge Field and Garatiana discovery in the North Sea. Then in the second half of 2018, Equinor acquired a 40% operator share in the Rosebank project on the U.K. Continental Shelf from Chevron. Other partners in the field are Suncor Energy (40%) and Siccar Point Energy (20%). This “agreement allows [Equinor] to buy back into an asset in which we previously had a participating interest, demonstrating our strategy of creating value through oil price cycles,” said Al Cook, Equinor’s executive vice president for global strategy and business development and U.K. country manager, in a press release.
In October 2018, the company started production at the Oseberg Vestflanken 2 Field in the North Sea. “Remote-operated from the Oseberg field center, the new Oseberg H platform is the first unmanned platform on the Norwegian Continental Shelf,” according to a press release.
In addition, in March of this year, Equinor (operator) and its partners, Petoro, ConocoPhillips and Repsol, made an oil discovery from the Visund A platform in the Telesto exploration well in the North Sea.

One of Saudi Aramco’s recent developments is the offshore Manifa oilfield megaproject located in the Arabian Gulf. Instead of building 30 offshore platforms, the company converted more than 70% of the field into an onshore field to avoid damaging the ecosystem. The design involved the creation of 27 man-made islands, all made from 45 MMcm (1.5 Bcf) of sand reclaimed from the seabed. The islands act as onshore drill sites above the offshore oil field, and they support equipment while elevated bridges allow normal flows of currents and sea life to continue. The development includes 14 bridges, 13 offshore platforms, 15 onshore drill sites, 350 new wells, injection facilities, multiple pipelines and a 420-MW heat and electricity plant. In 2017 the company reached its target of 900,000 bbl/d of oil.
“The result of the collaborative effort was an innovative plan to reach Manifa Field—primarily located in shallow water—through building a world-class causeway, bridges and laterals to connect the man-made islands,” the company stated in a 2017 media release. “The computerized modeling of the 27 drilling islands, connected by a 42-kilometer [26-mile] causeway and 14 bridges to allow natural water circulation at Manifa Bay, has significantly contributed to enhance the natural flow of water, maintaining the bay as a perfect environment for shrimp and fish populations to grow.”
Saudi Aramco said Manifa is one of the world’s largest engineering projects, noting that the construction phase alone required more than 4 million man-hours to complete, according to news reports.
In December 2017, Saudi Aramco released a new AUV that can conduct offshore platform debris surveys to identify seabed clearance and potential debris, a press release stated.

The Stones project began production in 2016 and is the deepest offshore oil and gas producing project in the world (2,896-m [9,500-ft] water depth), according to the company. It is estimated to have a peak annual production of 50,000 boe/d.
Offshore Brazil, Shell operates several producing fields in the Campos Basin: the Bijupirá and Salema fields (80% interest) and the BC10 Field (50% interest). The company’s operations portfolio also includes the Gato do Mato Field in the Santos Basin and the adjacent Sul de Gato do Mato area (80% interest). Additionally, Shell has 10 offshore exploration concessions in the Barreirinhas Basin (Shell’s interest ranges from 50% to 100%) and a presalt production-sharing contract (PSC) for the Shell-operated Alto Cabo Frio Oeste (55% interest).
Offshore Nigeria, Shell’s main deepwater activities are carried out by Shell Nigeria Exploration and Production Co. Ltd. (SNEPCO), which has interests in four deepwater blocks. SNEPCO operates oil mining licenses (OMLs) 118 and 135 and also has a 43.8% nonoperating interest in OML 133 and a 50% nonoperating interest in oil prospecting license 245.
Gumusut-Kakap, with a production capacity of 150,000 boe/d, was Shell’s first deepwater development in Malaysia, which started production in 2014. A Phase 2 development is in the execution phase, with first oil targeted for the third quarter of this year. Malika, which was Malaysia’s first tension-leg platform (TLP) and Shell’s first TLP outside of the GoM, began production in December 2016.
Offshore Mauritania, Shell signed two PSCs with the government for the exploration and potential future production of hydrocarbons in blocks C-10 and C-19 (Shell has 90% interest as operator) in July 2018, according to the report. The blocks are located in the West African Atlantic Margin exploration basin.
Shell also won nine deepwater exploration blocks offshore Mexico last year and will be the operator of all nine blocks.

Talos Energy Inc.
Talos Energy operates off the Gulf of Mexico (GoM), acquiring, exploiting and exploring the region. The company reported year-end 2018 proved reserves of 151.7 MMboe, of which 76% is proved developed, according to the company’s fourth-quarter and full-year 2018 financial and operational results report. Talos also reported production of 53,400 boe/d, or 4.9 MMboe, in the fourth quarter last year.
In May 2018, Talos Energy LLC and Stone Energy Corp. merged to form a new public company, Talos Energy Inc. The two companies completed a strategic transaction pursuant to which both became wholly owned subsidiaries of the company.
In the report, Talos CEO Timothy Duncan said, “The benefits of the combination have shown results immediately, as we are a stronger, free cash flow positive company with ample liquidity and a significant inventory of drilling locations in both the U.S. Gulf of Mexico and offshore Mexico. Our strategy of executing asset management and drilling projects around existing infrastructure in the U.S. Gulf of Mexico complements our high-impact exploration and development projects in offshore Mexico.”
The Helix Producer 1 drydock project was executed in the first quarter of this year by Talos and partner Helix Energy Solutions. Production subsequently restarted at the Phoenix complex in March. In addition, Talos is executing a series of deepwater subsea tieback projects, namely the Mt. Providence, Tornado 3 and Boris 3 wells. Talos expects to bring the Tornado 3 and Boris 3 wells online in April and May of this year, respectively, “which will put Talos in a position to grow production year over year while continuing to generate free cash flow in the current price environment for 2019,” the report stated.
In shallow water, the company’s asset management and drilling activities have allowed assets, such as Ewing Bank 305/306, to achieve production levels not seen in the last 15 years, according to Talos.
In January of this year, Talos acquired the Antrim stranded discovery from Exxon Mobil and entered into partnerships to drill two deepwater projects this year, the Bulleit and Orlov prospects.
On the Zama project, the company’s historic discovery offshore Mexico, Talos confirmed the oil-water contact per its geological model and encountered more sand than expected in the first downdip location, the report stated.
In addition, Talos will start to execute on the inventory it acquired as part of the cross-assignment of interest between Block 2 and Block 31, which includes the low-risk but high-impact Olmeca project on Block 31, according to the report.
Talos Energy announced on April 23 that it plans to release its first-quarter 2019 results report on May 8.
Total is the world’s fourth largest energy major and an integrated operator working across the entire oil and gas value chain in more than 130 countries.
In 2018 Total’s production grew more than 8% to a record level of 2,800 boe/d and led to a 71% increase in the company’s E&P net operated income. The year was highlighted by the startup of Ichthys in Australia, Yamal LNG in Russia, deepwater projects Kaombo North in Angola and Egina in Nigeria, as well as the counter-cyclical acquisitions of Maersk Oil and new offshore licenses in the United Arab Emirates.
This year the company has two startups planned in the North Sea, where Total became the second largest operator: Culzean (operator) with 100,000 boe/d and Johan Sverdrup with 440,000 boe/d (expansion to 660,000 boe/d). In addition, an investment decision is expected on the Glendronach discovery. “The [North Sea] region will contribute in a major way to the growth of Total’s production in the coming years,” a press release stated.
Total’s production in sub-Saharan Africa is led by the Gulf of Guinea comprising Angola, Nigeria, Congo and Gabon. The region, where Total operates 11 FPSOs, accounts for 25% of the company’s production.
In 2018 Total delivered positive news on exploration. It first announced a new discovery in the Gulf of Mexico (Ballymore, Chevron-operated). “This major discovery gives us access to large oil resources and follow-on potential in the emerging Norphlet play,” said Arnaud Breuillac, president of Exploration & Production at Total, in a company press release. “We will work together with Chevron on the appraisal of this discovery and a cost-effective scheme to ensure a rapid, low breakeven development.”
Total also successfully appraised the A6 Block (Shwe Yee Htun-2 discovery) offshore Myanmar and later announced two new gas finds in the North Sea (Glendronach and Glengorm in the U.K.).
Earlier this year, Total also discovered a new gas province offshore South Africa with the discovery on the Brulpadda prospect. “With this discovery, Total has opened a new world-class gas and oil play and is well positioned to test several follow-on prospects on the same block,” a company press release stated.
In addition, Total has set a number of objectives to integrate climate into its strategy, which includes reducing 15% greenhouse gas emission (scopes 1 and 2) by 15% on operated oil and gas facilities as well as reducing the intensity of methane emissions of the E&P segment’s operated facilities to less than 0.2% of the commercial gas produced by 2025, the company stated in its 2018 Registration Document released in March 2019.
