Columbus Energy Resources PLC (LON:CERP) told investors that work is continuing with partner Predator Oil & Gas to advance the enhanced oil recovery pilot project in the Inniss-Trinity area, in Trinidad.
The company, in a statement on Thursday, note that it has successfully completed workover operations to survey the AT-4 and AT-13 wells downhole. This work is prerequisite to future gas injection programmes.
Predator has informed the company that, based on the AT-13 findings, the Herrera #2 Sand has been selected as being accessible for CO₂-driven enhanced oil recovery (EOR).
In effect, this has meant that the previously surveyed AT-5X well and the AT-13 well have been identified as the preferred initial wells for CO₂ EOR operations.
"Columbus and Predator continue to advance the CO₂ pilot project,” said Leo Koot, Columbus chief executive.
“We believe the CO₂ pilot project on Inniss-Trinity will give all parties a valuable insight into an alternative enhanced oil recovery mechanism for Trinidad and has the potential to transform oil & gas operations in the Inniss-Trinity field and in similar fields in Trinidad.
“We look forward to working with Predator to further advance the project."
