From Guyana to Trinidad exploration is getting bigger and faster
ExxonMobil is accelerating exploration on Trinidad and Tobago's TTUD-1 block, expecting seismic data by late 2026 and drilling by 2027-2028, according to VP John Ardill. The company is moving faster than in Guyana, with Occidental holding a 10% stake. Shell's CEO regretted exiting Guyana's Stabroek Block early.

Why it matters
The announcements signal a fresh growth catalyst for both ExxonMobil and Occidental, though the benefits are long‑term and contingent on seismic results and successful drilling.
Market read
The new exploration schedule and partner stake could modestly lift energy sector sentiment and add a long‑term supply source, with limited immediate price impact.
What to watch
Regulatory approvals, financing terms, and potential competition from other deepwater projects could affect the ultimate value of the block.
Background
ExxonMobil's TTUD-1 block is a 7,765 km² ultra‑deepwater area off Trinidad, linked to the prolific Stabroek discovery in Guyana. Occidental's 10% stake adds a new partner to the project.
Ticker impact
ExxonMobil announced accelerated TTUD-1 exploration, expects processed seismic images by end‑2026 and plans to drill an exploration well in late‑2027 or early‑2028.
