Petronas Offshore Colombia Gas Find Arrives With Depletion Clock Ticking
Colombia's new offshore discovery lands just as analysts forecast the country's economically recoverable domestic gas runs out by 2039.
Malaysia's state energy firm Petronas has made a natural gas discovery offshore Colombia, announced the week of 2026-08-10, adding another well to a run of exploration success across the northern South American margin. No resource estimate has been disclosed.4
The timing gives the find its significance. Analysts forecast that economically recoverable natural gas in Colombia will be depleted by 2039, with commercial production expected to continue until that date, per oilprice.com reporting from July 7, 2026. That leaves roughly 13 years — a tight window for any offshore project to reach first gas, complete appraisal drilling, secure financing, and build export or domestic infrastructure.4
Colombia's supply problem is already biting before any new field enters production. Declining output and a widening supply gap are the backdrop, and both worsen sharply if a potential Super El Niño arrives in the second half of 2026, as the same oilprice.com reporting warned. Reduced hydro generation during a dry spell would push more load onto gas-fired power, straining import capacity and driving up procurement costs at exactly the moment domestic reserves are thinning.4
Petronas is arriving in Colombia with momentum built elsewhere on the Atlantic margin. In early July (2026-07-02), the Malaysian national company announced two new discoveries and a successful appraisal well in Block 52 off Suriname, bringing its total in that block to eight successful wells, per a company press release reported by Rigzone. That is a materially more developed picture than what Colombia shows at this stage.3
The Suriname position is already moving toward a development decision. Suriname's president said, in the week of 2026-06-22, that Petronas expects to reach a final investment decision on the block, as quoted by Reuters. The contrast with Colombia is direct: eight successful wells in Suriname versus an undisclosed find in Colombian waters, with no appraisal programme announced.2
Across the continent, Argentina is separately advancing its first LNG export project. Adani Ports secured a 10-year marine services contract for that venture in June (2026-06-08), per the Free Press Journal, committing $70 million to expand operations in the region. Argentina's project targets export markets rather than domestic supply relief, but it signals that South American gas is moving toward commercialisation across multiple fronts.1
The global price environment adds context. Asian LNG benchmark JKM stood at $21.11 per MMBtu in early trading on 2026-08-10, while ICE Endex TTF front-month settled at €55.50 per MWh on 2026-08-09. Neither level reflects panic buying, but both are high enough that new Atlantic-basin supply draws attention from buyers looking to diversify away from existing LNG contracts.
For Colombia specifically, the commercial logic for developing offshore gas is straightforward on paper. Domestic supply is shrinking, gas-fired demand would rise sharply under El Niño conditions, and import infrastructure is limited. Without new domestic supply, Colombia faces a choice between ramping LNG imports at spot prices or accepting power rationing during dry spells.4
But Petronas has disclosed nothing about appraisal plans, water depth, reservoir quality, or fiscal terms negotiated with Bogotá. Colombia's government has sent mixed signals on new hydrocarbon exploration, and investors will want clarity on licensing terms before committing capital to a project racing a hard depletion deadline. Those signals matter as much as the geology.4
The near-term read for traders is limited. A discovery without appraisal numbers does not shift Colombia's import requirements for several years at minimum. The more actionable signal in the region remains Petronas's Suriname programme, where eight wells and an impending FID discussion suggest Atlantic-basin LNG feedstock or pipeline supply could materialise by the early 2030s.2,3
The specific thing to watch now is whether Petronas announces an appraisal well in Colombian waters and whether Bogotá moves to accelerate permitting. A fast-tracked development could still miss the 2039 window by years. If El Niño hits late 2026 as feared, Colombia may find itself paying elevated LNG import prices while its own offshore gas sits unappraised.4
