Santos Limited (STO.AX) has greenlit the Agogo Production Facility tie-in project in Papua New Guinea, opting to boost gas output for the current PNG LNG system instead of constructing a separate export terminal. The move came after the PNG LNG joint venture—where Santos owns a 39.9% stake—signed off.
Timing is key here. Santos wants the market focused on ramping up output and hitting project milestones, especially after setbacks like the Barossa holdups and missing first-quarter targets. Shares finished Wednesday at A$7.68, gaining 1.59%—this after a 0.53% lift the day before.
Signing off on an FID means the project gets the official green light. According to Santos’ ASX filing, the Agogo plan calls for a 19-kilometre pipeline, a pair of new wells, and changes to the production facility. The goal: first gas in the second quarter of 2028.
Gross capital expenditure sits around $400 million over three years. Out of that, Santos will cover about $160 million. The company said this amount is already factored into its capital expenditure guidance.
The project should boost capacity by roughly 135 mmscf/d — that’s million standard cubic feet a day, the usual metric for gas flow. Of that, Santos’ net share lands at approximately 54 mmscf/d, according to Reuters.
Chief Executive Kevin Gallagher described Agogo as a “high-quality development with strong economics,” adding it’s set to convert 66 million barrels of oil equivalent in 2P undeveloped reserves into developed ones. In industry terms, 2P refers to proved and probable reserves—resources that are expected to be recoverable.
The filing pegged the internal rate of return—used to gauge project profitability—at over 50%. The timeline for payback lands under four years from FID, and about two years after first gas.
Brett Darley, Santos’ Australia and PNG chief operating officer, says “key regulatory approvals are in place.” Up next? Less headline-grabbing tasks: finalizing detailed design, locking in two primary construction contracts, plus organizing a temporary construction camp.
It’s PNG LNG that frames the competition here—not a solo contest. Santos teams up with ExxonMobil PNG, ENEOS Xplora, and Kumul Petroleum, tapping into the established PNG LNG facilities. That lets them boost feed gas volumes with a lighter expansion, skipping the costs and scale of a greenfield LNG build.
Investors were already watching the broader picture. Back in April, Reuters noted that Santos stuck with its 2026 production and sales guidance—still calling for 101 million to 111 million barrels of oil equivalent—despite quarterly output taking a hit from Barossa downtime and weather delays.
Saul Kavonic, who leads energy research at MST Marquee, pointed out at the time that investors were shrugging off the revenue miss, with Barossa and Pikka “around the corner.” Agogo, though, is further out—a similar narrative, more gas, more reserves slated for production, just not before 2028.

Risk hasn’t disappeared. First gas remains two years out, with construction contracts still unsigned. Santos pointed out that any upside hinges on how the reservoir performs. If costs climb, drilling hits snags, or production ramps up slowly, defending those high-return projections gets tougher.
Australian gas stocks aren’t immune from policy jitters, despite this project sitting offshore in PNG. Last week, Australia announced that LNG exporters on the east coast — among them, a Queensland project run by Santos — will need to hold back 20% of their gas for local buyers starting July 2027. Analysts speaking to Reuters warned this could ramp up regulatory risk and dent the appeal of any future LNG developments.
Santos spelled it out in the Agogo filing: stick with familiar infrastructure, keep spending within the stated range, and boost feed gas to PNG LNG. Now, the market’s got its eye on a fresh target — second-quarter 2028.
