Columbus starts CO2 injection in Trinidad field

Columbus Energy Resources PLC has begun Phase 2 of a CO₂ pilot project in Trinity Inniss field, Trinidad, following approval from the Ministry on Energy and Energy Industry for continuous injection in the field.

Phase 1 began in January when Columbus injected a tank of CO₂ into well AT5X to determine production impact in offset wells. Phase 2 is to maintain CO₂ injection at optimum 9 metric tonnes/day peak rate. Impact of continuous CO₂ injection on offset wells production will be monitored.

Innis-Trinity is a mature field producing from Herrera turbidite sands. The field has produced 23 million bbl to date with 4.0 million bbl estimated recoverable reserves.

Predator Oil and Gas PLC will help plan and fund the CO₂ EOR pilot project. After Predator recovers project-related costs, Columbus and Predator will have 50% interest in any incremental oil production.
