Chevron has told Peru it wants out. The US major has informed Perupetro, the state agency that manages Peru's hydrocarbon licence contracts, of its intention to relinquish its stake in offshore blocks Z-61, Z-62 and Z-63 in the Trujillo Basin

The letter was sent in mid-July, in the final weeks of caretaker president José María Balcázar's government. Balcázar had led Peru on an interim basis since February, after Congress removed his predecessor, José Jerí. Keiko Fujimori, who won April's general election, took office on July 28 and has moved quickly to align her government with Washington, naming a foreign minister who previously worked as communications director at the US Embassy in Lima and describing the US as a "strategic partner." The timing nonetheless underscores how little Peru's political transition featured in Chevron's decision: this was a capital allocation call made in Houston, not a reaction to events in Lima.

A courtship that fell short of a year

Chevron's arrival was billed as a coup for Peru's upstream sector. In September 2025 it signed amended licence agreements for the three blocks alongside Anadarko Peru Limited Sucursal Peruana (Anadarko), the operator and a subsidiary of US independent Occidental Petroleum, and Westlawn Perú S.A.C. (Westlawn), the local arm of an investment fund. Anadarko kept a 35% operating stake, Chevron took 35% and Westlawn held the remaining 30%, across blocks covering more than 1.8mn hectares roughly 50 nautical miles off the coasts of La Libertad and Lambayeque, in waters ranging from 100 to 2,400 metres deep. Then-president Dina Boluarte attended the signing and presented it as proof of Peru's pull with global energy majors.

The consortium's calling card was data, not drilling. Between May and July 2024 it completed a 3D seismic survey covering 6,018 square kilometres, the largest ever carried out on Peru's continental shelf and along the wider Pacific coast. Perupetro said at signing that a discovery could eventually support production of 100,000 to 150,000 barrels per day (bpd); later, more optimistic official commentary put the figure as high as 300,000 bpd, a spread worth flagging given none of it has been tested by a drill bit. The partners were due to decide this year whether to commit an estimated $100mn-150mn to an exploratory well in block Z-62, originally pencilled in for December.

Chasing faster barrels

Chevron's exit fits a pattern visible in its own numbers. The company reported record worldwide production of 3.7mn barrels of oil-equivalent per day in 2025, up 12% on the year, driven chiefly by its acquisition of Hess Corp, which brought a stake in Guyana's prolific offshore Stabroek Block, alongside the ramp-up of the Future Growth Project at Tengizchevroil in Kazakhstan and continued growth in the US Permian Basin. Each of those assets was already producing or close to it. Peru's Trujillo Basin, by contrast, was still years from a first barrel even in the most favourable scenario.

El Comercio reported that Chevron is redirecting capital toward jurisdictions offering quicker paths to production, naming Kazakhstan and Venezuela specifically. On Venezuela, the logic is straightforward: Chevron's existing joint ventures with PDVSA in the Orinoco Belt and Lake Maracaibo already produce an estimated 250,000-280,000 bpd, a base that has only gained upside since Caracas's oil-sector deregulation and Washington's parallel easing of sanctions this year. Peru offered Chevron the promise of a discovery years out. Venezuela and Kazakhstan offer barrels now.

The fallout for Lima

The immediate consequence falls on Anadarko and Westlawn, which must now find a replacement partner or shelve the Z-62 well altogether. Neither Peru's Ministry of Energy and Mines (Minem) nor Perupetro had responded to requests for comment by the time Peruvian outlets went to press.

The bigger cost is reputational. Boluarte's government sold Chevron's entry as validation of Peru as an investment destination; Fujimori's administration inherits the opposite signal, delivered before a single exploratory well was spudded. Frontier offshore exploration is a game of patient capital and high risk tolerance. Peru's pitch leaned on the size of the prize. Chevron's exit suggests that, for a company now flush with faster-paying options elsewhere, the prize alone was never going to be enough.
