Chevron Corp. began producing oil and pure fuel from the Anchor discipline on america aspect of the Gulf of Mexico (GOM), the power big introduced Monday, saying the undertaking is the primary to efficiently deploy a high-pressure deepwater expertise.
“The Anchor undertaking represents a breakthrough for the power {industry}”, Nigel Hearne, govt vice chairman at Chevron Oil, Merchandise & Gasoline, mentioned in an organization assertion. Chevron mentioned the expertise, which consists of parts for drilling, completion, intervention and subsea manufacturing, can safely function at as much as 20,000 strain per sq. inch in reservoirs which can be 34,000 ft beneath sea degree.
“Software of this industry-first deepwater expertise permits us to unlock beforehand difficult-to-access sources and can allow related deepwater high-pressure developments for the {industry}”, Hearne added.

Transocean Ltd.’s newly constructed Deepwater Titan drilled Anchor’s subsea high-pressure manufacturing wells.
The undertaking employs a semisubmersible floating manufacturing unit (FPU) with a every day capability of 75,000 gross barrels of oil and 28 million gross cubic ft of fuel, which can provide Gulf Coast markets within the U.S. The Anchor growth may have seven subsea wells tied to the FPU, stationed within the Inexperienced Canyon space about 140 miles off the Louisiana coast and positioned on waters about 5,000 ft. Found 2014, the sector holds doubtlessly recoverable sources of round 440 million barrels of oil equal (boe).
Chevron operates Anchor with a 62.86 p.c stake via Chevron USA Inc. TotalEnergies SE owns the remaining 37.14 p.c by way of TotalEnergies E&P USA Inc.
“This Anchor milestone demonstrates Chevron’s potential to securely ship tasks inside price range within the Gulf of Mexico”, mentioned Bruce Niemeyer, president at Chevron Americas Exploration & Manufacturing.
Chevron targets to develop its manufacturing within the Gulf of Mexico to 300,000 internet boe per day (boepd) by 2026. With the brand new startup, it now has six amenities working within the U.S. Gulf of Mexico, based on the corporate.
“The Anchor undertaking offers reasonably priced, dependable, decrease carbon depth oil and pure fuel to assist meet power demand, whereas boosting financial exercise for Gulf Coast communities”, Niemeyer added. The FPU is an all-electric platform that additionally makes use of an present pipeline to move manufacturing, in addition to makes use of waste warmth and vapor, based on Chevron.
Chevron mentioned the U.S. Gulf of Mexico is “one of many lowest carbon depth oil and fuel basins on this planet”.
In a separate assertion, Nicolas Terraz, TotalEnergies president for exploration and manufacturing, mentioned, “The startup of Anchor is a brand new milestone within the deployment of TotalEnergies’ built-in power mannequin within the US, combining the event of oil tasks with a excessive leverage to cost and a low emissions depth and progress in Built-in LNG and Built-in Energy”.
Want for New Know-how
Rising demand for pure fuel within the U.S. is anticipated to drive the deployment of latest applied sciences in in any other case inaccessible reserves.
“There may be an elevated demand for brand spanking new sources of pure fuel, together with doubtlessly elevated exports because of world fuel market disruptions”, Upwing Power Inc. Herman Artinian informed Rigzone late final yr. “Colliding with elevated power demand, latest geopolitical conflicts have destabilized a few of our most dependable hydrocarbon producers”.
U.S. producers will search “new methods to make sure it has ample pure fuel inventories and entry to reserves to maintain the power calls for of its residents”, Artinian mentioned. “To deal with uncertainty in power safety, producers will extra readily embrace applied sciences that assist them attain beforehand inaccessible home reserves of pure fuel”.
Upwing earlier mentioned in a report that primarily based on analysis it had carried out, over 123 trillion cubic ft of fuel stay untapped within the nation’s deserted and non-economically viable standard fuel wells. That determine is sufficient to energy the U.S. for about 4 years, based on the Cerritos, California-based power tech firm.
Whereas producers may additionally flip to unconventional wells, these reserves provide a decrease restoration charge at excessive prices and emissions, Upwing mentioned.
Artinian expects 2024 to “see elevated pricing of pure fuel and the daybreak of latest applied sciences that may pull the remaining fuel out of those partially extracted wells, concurrently serving to the nation meet rising demand and boosting sustainable manufacturing by eliminating the necessity to drill and frack new wells”.
“The U.S. will proceed to depend on pure fuel as a core a part of its power combine for many years to come back, so new tech options to supply, course of, and distribute fuel extra effectively shall be essential to assist its ongoing use”, Artinian mentioned.
In Norway, one other main fuel exporter, most pure fuel in offshore reserves additionally stays untapped because of the lack of expertise to penetrate tight reservoirs. About 65 p.c of fuel sources on the Norwegian continental shelf have but to be produced and may have new expertise to be extracted, the Norwegian Offshore Directorate reported final December.
Nearly all of confirmed fuel sources with out growth plans sit in tight reservoirs, that are reservoirs with low permeability or stream, it mentioned. It additionally cited excessive strain and temperature and fuel high quality as challenges within the subsurface that discourage builders.
Tight reservoirs “usually can’t be produced utilizing standard wells; worthwhile manufacturing can solely be achieved by implementing measures to enhance fuel stream”, the Directorate mentioned. “Thus far, numerous types of fracturing and multi-branch wells stay probably the most related strategies for recovering sources in tight reservoirs.
“Slim-hole expertise can also be related in a number of locations, the place numerous slim boreholes in the identical nicely will improve the wells’ contact floor with the reservoir (reservoir publicity) and make it simpler for hydrocarbons to stream into the wells”.
Such strategies have already been deployed within the Norwegian shelf however primarily for oil extraction, based on the Directorate. “Elsewhere on this planet, corresponding to within the Gulf of Mexico, the UK shelf and on sure onshore fields, the applied sciences have been used to supply fuel”, it famous.
