Why are oil majors pouring $9.2 billion into the Gulf of Mexico over two years?

After completing its $53 billion acquisition of Hess, Chevron not only gained access to massive assets offshore Guyana but also unexpectedly became the largest leaseholder in the Gulf of Mexico—80% of its newly acquired blocks lie within 50 kilometers of existing infrastructure, meaning smaller discoveries can be rapidly monetized via tie-backs. Take the Balmorel field as an example: it connects to the 'Blind Faith' platform via a 12-kilometer subsea pipeline, cutting development costs by 60% compared to building a new platform. Chevron expects its net production in the Gulf of Mexico to reach 300,000 barrels of oil equivalent per day by 2026—a 40% increase over 2023 levels. 02 Differentiated Strategies by Other Oil Companies Beyond the three major players, the Gulf of Mexico’s market landscape is being reshaped by additional participants—some entering via acquisitions, others focusing on niche segments—creating a complementary and competitive dynamic. 1 Occidental Petroleum (Oxy) is a classic 'latecomer': it entered the Gulf of Mexico market in 2019 through its acquisition of Anadarko Petroleum. Its daily production peaked at 147,000 barrels of oil equivalent in 2022. Though slightly lower since then, Oxy remained highly active in the December 2023 lease auction, securing 49 blocks—the second-highest number after Shell—demonstrating its continued commitment. 2 Equinor (Norway’s state-owned oil company) pursues a core strategy centered on 'non-operated interests'. In Q2 2025, it achieved a net daily production of 129,000 barrels of oil equivalent in the region, ranking fourth—slightly ahead of Occidental. 3 TotalEnergies (France) has opted for a 'joint development' approach: in June 2025, it acquired 25% stakes in 40 blocks operated by Chevron. This deepens an already established partnership; previously, TotalEnergies held a 40% stake in Chevron’s Balmorel project, expected to add nearly 30,000 barrels of oil equivalent per day to its net production at peak output. 03 Why the Gulf of Mexico? A confluence of advantages—including resource endowment, technological maturity, and favorable policy conditions—makes the Gulf of Mexico irreplaceable even amid the energy transition. First, abundant resource reserves. According to data from the U.S. Bureau of Ocean Energy Management (BOEM), the Outer Continental Shelf (OCS) of the Gulf of Mexico hosts 1,325 oil and gas fields with 'original recoverable resources' (cumulative production plus remaining reserves) totaling 26.77 billion barrels of oil and 197.0 trillion cubic feet of natural gas. Vast unexplored areas remain—on November 2021, the U.S. held its largest-ever offshore lease sale, covering approximately 80.9 million acres (about 32.74 million hectares); Chevron emerged as the top bidder with $47.1 million, followed closely by BP, Shell, and ExxonMobil—underscoring the region’s enduring resource appeal. Technological breakthroughs have removed barriers to deepwater development. Over decades, industry advancements have progressively extended drilling operations into deeper waters. The deepest known hydrocarbon discovery in the Gulf lies in Lloyd Ridge Block 370, at a water depth of 9,975 feet (~3,041 meters). Moreover, over 70% of the region’s oil production now comes from wells located in water deeper than 1,000 feet (~305 meters). High economic value remains the core driver behind corporate decisions.

Oil under the U.S.-Venezuela agreement may enter U.S. strategic reserves in November; Chevron plans $7 billion investment to expand Venezuelan production, pushing its stock to a record high.

White House spokesperson Anna Kelly stated during an interview that crude oil obtained under the U.S.-Venezuela agreement could enter the U.S. strategic reserve system as early as November. According to CCTV News, on September 2, Venezuela’s acting President Delcy Rodríguez met with U.S. Energy Secretary Chris Wright. Following the meeting, the two countries formally signed multiple cooperation agreements. Recently, former U.S. President Donald Trump announced on social media that the United States had reached an agreement with Venezuela granting it 'majority control' over more than 65 billion barrels of Venezuela’s proven oil reserves. Venezuela’s acting President Delcy Rodríguez stated that the oil cooperation agreement with the U.S. will last 25 years, aiming to raise Venezuela’s crude oil output to 1.5 million barrels per day while safeguarding Venezuela’s sovereign rights over its natural resources. Venezuela’s current daily production stands at approximately 1.25 million barrels—far below its late-1990s peak of 3 million barrels per day. Chevron commits over $7 billion to double output in five years Chevron’s deal represents the largest single transaction in this round. The company plans to invest over $7 billion over the next five years through joint ventures to develop the Carabobo 1 and Carabobo-2-South-A fields—both adjacent to Petroindependencia, a joint venture in which Chevron holds a 49% stake. The goal is to raise Chevron’s oil production in Venezuela to 600,000 barrels per day within five years—double its current level. CEO Mike Wirth said the company is establishing a 'substantive strategic position' in Venezuela, noting that these two fields 'contain several billion barrels of resource equivalents.' Wirth added that certain Venezuelan reserves previously written down by the company years ago will now be reinstated on its books, and the agreement includes 'significant protective mechanisms.' Chevron typically transports Venezuelan crude to refineries along the U.S. Gulf Coast; with total lifting costs below $20 per barrel and Brent crude trading around $95 per barrel, the project offers substantial profit margins. The signing ceremony took place at Miraflores Palace in Caracas. Chevron is one of the few major international oil companies to have maintained operations in Venezuela following former President Hugo Chávez’s 2007 nationalization of oil assets—and this agreement further solidifies its strategic foothold there. ENI enters the Orinoco Belt, prioritizing tangible output In addition to Chevron, Italy’s ENI secured a 25-year exclusive operating contract for the Junín 5 block and will begin drilling this Thursday. CEO Claudio Descalzi described the block as holding over 35 trillion cubic feet of natural gas—'a huge potential'—and said ENI plans to submit its development plan for the block in October. ENI CEO Claudio Descalzi stated bluntly at the ceremony: 'We don’t just need signed documents—we need actual barrels produced.'
