(Alliance News) - Predator Oil & Gas Holdings PLC on Thursday reported completion of workover operations at the Inniss-Trinity field, onshore Trinidad.
Fram Exploration Trinidad Ltd, the operator of the Inniss-Trinity field and a wholly-owned subsidiary of Columbus Energy Resources PLC, has completed operations to survey downhole the AT-5X well in preparation for future CO2 injection and enhanced oil production, Predator said.
The exploration company said its downhole completion design to potentially achieve optimum efficiency for CO2 EOR injection by isolating specific reservoir sands was determined as being operationally viable.
In preparation for CO2 EOR operations, a key interval of reservoir section chosen for the first CO2 injectivity test was successfully isolated from the deeper reservoirs with the setting of a cast iron bridge plug.
The workover rig will now move on to survey the AT-4 well, Predator said.
"We are pleased that the workover of AT-5X has been successfully completed and that the first stage of the operational strategy for focussed CO2 injection has been proven to be possible to implement in old producing wells," said Predator Chief Executive Paul Griffiths.
"This strategy is unique in terms of what has previously been attempted using C02 in Trinidad and we are excited about the possibilities that lie ahead," added Griffiths.
Predator shares were trading 6.5% higher in London on Thursday at 4.95 pence each.
