Tetragon Energy

What Tetragon Energy does

Tetragon Energy Limited (ASX: TET) is an early-stage, pre-revenue oil and gas exploration company focused exclusively on the Philippines, where it operates two offshore Service Contracts in the Sulu Sea (SC-80, SC-81) and one onshore Service Contract in the Cagayan Basin (SC-82). The company was established in March 2026 as a spin-out from Triangle Energy and completed its ASX listing in July 2026 at an A$8 million market capitalization. The portfolio currently contains 470 Bcf of contingent gas resources plus 5 MMbbl of condensate (2C) from the Dabakan-1 and Palendag-1A discoveries in SC-80, 13-15 Bcf of contingent gas onshore SC-82, and the Halcon prospect which was upgraded in September 2026 to 8.0 Tcf of gross mid-case prospective resources with a 24% geological chance of success.

The core technical activity is subsurface maturation via a $1.45 million seismic reprocessing program covering more than 4,000 km² outsourced to DUG Technology, designed to improve imaging across SC-80 and SC-81 in support of farm-out discussions with major oil and gas companies. The company's go-to-market is enterprise field sales targeting JV and farm-in partners rather than direct product distribution; revenue, when generated, will come from gas and condensate sales to the Philippine power-generation market once discoveries are developed. Sunda Energy already holds a 37.5% working interest in SC-80, making it the only disclosed commercial counterparty today.

Tetragon's customer base is effectively the small group of Philippine and regional utilities that will eventually purchase gas, while its immediate commercial counterparties are major E&P companies evaluating farm-in participation. The leadership team — Managing Director Conrad Todd, COO Sam Algar (formerly Cairn, Beach Energy, Oil Search, Murphy Oil), CFO Marvin Chan, and Non-Executive Chairman Greg Hancock — provides substantial industry pedigree but the business remains capital-constrained and pre-discovery relative to peers.
