Gran Tierra Energy Inc. Announces Completion of Conditions Precedent for Tisquirama Contract
Gran Tierra clears the final hurdle on Tisquirama, unlocking a 49% stake in Colombia’s next waterflood growth engine, but the market had already priced in the partnership.

On May 27, 2026, Gran Tierra Energy announced that all conditions precedent for its contract with Ecopetrol S.A. have been satisfied, making the agreement effective to earn a 49% working interest in the Tisquirama block (Middle Magdalena Valley Basin, Colombia). Phase 1 capital activities will now commence, focusing on waterflood expansion from the operated Acordionero field into the Tisquirama and San Roque fields, with a minimum gross investment of $15 million. Upon completing Phase 1 (expected Q1 2027, subject to executive committee approval), Gran Tierra will receive 49% of both existing base production and incremental production from the block, where gross output averaged ~2,500 boepd during 2025.
The breakthrough is incremental rather than transformational. The strategic partnership was already announced on March 17, 2026, and covered in detail during the Q1 2026 earnings transcript. Satisfying the conditions precedent was widely expected; the contract was subject to standard regulatory and closing conditions. While it formally de‑risks the transaction and triggers the start of field work, it does not introduce new upside beyond what was previously disclosed. Consequently, the news is positive but falls squarely into the “routine” category — a necessary step that was already anticipated by the market.
Gran Tierra Energy is a Canada‑headquartered, internationally diversified oil and gas producer with core operating areas in Colombia, Ecuador, and Canada, and a new exploration venture in Azerbaijan. The company’s flagship asset is the Acordionero field (Middle Magdalena Valley, Colombia), a large, long‑life conventional oil field where advanced waterflood has driven recovery. The recent Tisquirama block partnership extends that waterflood play into an adjacent, geologically analogous field, with the potential to replicate Acordionero’s 16% recovery factor on a resource of ~364 million barrels of original oil in place. Other key assets include the Cohembi field (Colombia, ongoing infill drilling), the recently acquired Perico/Espejo blocks and the Iguana discovery in Ecuador, and Canadian Montney/Glauconitic gas‑weighted production. The Azerbaijan EDPSA adds high‑impact exploration upside.
