Venezuela holds roughly 20 percent of the world’s proven oil reserves. That fact has not changed. What changed in January 2026 was the legal framework.

First, the U.S. Treasury issued General License No. 46. The license allows American companies to transact with PDVSA, Venezuela’s state oil company. At the same time, Venezuela’s National Assembly reformed its oil laws. The reforms allow foreign companies to control production, manage cash flows, and resolve disputes outside Venezuelan courts.

That combination unlocked activity.

The legal complexity remains extreme. Companies must determine who their counterparty really is, since the U.S. still recognizes the 2015 National Assembly as Venezuela’s legitimate government. They must comply with Executive Order 14373, which places Venezuelan oil revenues under U.S. government custody. The order shields those revenues from billions in creditor claims, including ExxonMobil’s $1.6 billion arbitration award and ConocoPhillips’ settled $2 billion claim.

Sanctions compliance still matters. The license continues to bar dealings with Chinese, Iranian, and Russian entities. Infrastructure risk also looms large. Industry estimates put the cost of restoring production at roughly $100 billion over ten years.

This is not simple deal work. It spans international arbitration, sovereign debt, sanctions, energy regulation, and political risk. Firms will not win this work through RFPs. They will win it through existing client relationships.

We identified likely participants using three filters: existing Venezuelan presence or claims, financial capacity measured by market capitalization, and public strategic signals. That produced eleven companies across four tiers.

Tier 1: Already There or Coming Back

Chevron ($282B market cap) remains the only U.S. major operating in Venezuela under Treasury license. ExxonMobil ($515B) and ConocoPhillips ($135B) exited in 2007 after nationalization. Both still hold arbitration leverage that matters in any re-entry discussion.

Tier 2: Opportunistic Players

Occidental Petroleum ($48B), Marathon Petroleum ($52B), and Hess Corporation ($45B) fit this category. Each has signaled interest in distressed assets, operates heavy-oil refineries, or runs assets in neighboring countries with transferable expertise.

Tier 3: Service Companies

Schlumberger ($63B), Halliburton ($31B), and Baker Hughes ($33B) provide the technology and equipment that make production possible. They maintained varying degrees of Venezuelan presence through 2020. They will follow operator clients back in.

Their risk profile differs. They bill for services rendered, regardless of who owns the oil. Their legal work centers on service contracts, licensing, and liability allocation.

Tier 4: Refining-Focused Buyers

Phillips 66 ($46B) and Valero Energy ($42B) are downstream refiners with heavy crude capability. They are buyers, not producers. Their legal needs skew toward commercial contracts and sanctions compliance, not production-sharing or political risk insurance.

Together, these eleven companies account for most foreseeable Venezuela-related legal spend.

Jones Day leads the rankings for one clear reason: Chevron.

The firm handled 103 public matters for Chevron alone. That figure is nearly 2.5 times larger than the next biggest firm-client pairing, Bracewell’s 43 matters with Phillips 66. Since Chevron is already operating in Venezuela and holds Treasury approvals, Jones Day’s position is structural.

Any expansion flows through existing counsel.

Jones Day also appears among the largest pairings with Marathon Petroleum, at 23 matters. That dual exposure to two of the eleven target companies creates depth competitors cannot replicate quickly.

Latham & Watkins ranks second with 110 matters. King & Spalding follows with 97. Both show broader client spread across the eleven targets.

Practice area data from Pirical adds context. Litigation accounts for 338 matters, second only to M&A at 446. That matters in Venezuela.



King & Spalding’s 15-matter relationship with ConocoPhillips positions it well for arbitration and dispute work tied to legacy claims. White & Case, with 23 Occidental matters and 15 Hess matters, sits squarely in the lane of greenfield structuring and political risk mitigation.

Sidley Austin holds 30 matters across the dataset, including 15 with Halliburton. Davis Polk shows a parallel 15-matter relationship with Baker Hughes.

Service company work rarely grabs headlines. It does generate volume. These companies need master service agreements, licensing terms, procurement contracts, and insurance structures in high-risk environments. The work is steadier than operator equity deals.

Paul, Weiss logged 61 matters with just 37 lawyers. That produces the highest matters-per-lawyer ratio among top firms. In a market where arbitration clauses and sovereign immunity questions appear in nearly every deal, efficiency matters.



Davis Polk controls the largest ExxonMobil relationship in the dataset, with 34 matters. If ExxonMobil decides to convert its arbitration award into leverage for re-entry, Davis Polk will already be inside the decision loop.

Kirkland & Ellis ranks near the top overall, but its exposure skews toward Marathon Oil Group and service companies rather than Chevron, ExxonMobil, or Hess. That mix signals strength in broader energy work without the same operator concentration that will likely drive early Venezuela decisions.



That is not a flaw. It is a strategic reality.

The same pattern appears for Skadden, Vinson & Elkins, and Sullivan & Cromwell. All have strong energy practices. None show dominant exposure to the specific companies most likely to move first.

Firms outside the top 20 face an even steeper climb unless they bring specialized sanctions, arbitration, or sovereign debt expertise that justifies breaking existing counsel relationships.

Firm rankings only tell part of the story. Practice area distribution shows where legal risk and spend actually concentrate once activity begins. Pirical data makes the pattern clear.



Litigation does not trail far behind M&A. Insurance and product liability work ranks higher than capital markets and environmental matters. That matters in Venezuela, where degraded infrastructure, legacy equipment, and accident risk will drive claims early.

Beyond BigLaw, several U.S. litigation boutiques show outsized oil and gas exposure. Carver Darden leads with 19 matters handled by just five lawyers. That is a 3.8 matters-per-lawyer ratio.



Kobre & Kim, Beck Redden, and Gibbs & Bruns show similar patterns. These firms will not structure deals. When disputes arise, operators already trust them.

Venezuela is not a purely U.S. story.



Clifford Chance, Osler Hoskin & Harcourt, Freshfields, and A&O Shearman all rank in the top 20. Their experience in international arbitration, sovereign debt, and cross-border regulation fills gaps U.S. firms sometimes lack.

The top firms hold a real advantage. They are already embedded.

If Chevron expands, Jones Day does not pitch. If ExxonMobil acts on its award, Davis Polk is already advising. If ConocoPhillips negotiates under the new oil law, King & Spalding brings institutional memory others lack.

The work will not stay transactional. Creditors frozen out by Executive Order 14373 will litigate. Sanctions licenses will evolve. Contract disputes will cross jurisdictions. Political risk will shift month to month.

Firms with deep litigation and arbitration benches may capture more value than headline deal volume suggests. The data points to Paul, Weiss, White & Case, and King & Spalding.

Service companies add a second pipeline. Schlumberger, Halliburton, and Baker Hughes will follow their clients and bill consistently. Kirkland, Sidley Austin, and Davis Polk benefit from that steadier flow.



The market is largely spoken for. The open question is staffing. Can the firms that win actually handle the surge when it arrives?
