Icacos Field Update, Trinidad

LGO today announces that production has been fully restored from existing wells and has been enhanced by the reactivation of a previously dormant well at the Icacos Field (LGO 50%, non-operator).

Further to the announcement made on 12 June 2013 when it was indicated that work-over activity was required on the Icacos Field in the Cedros Peninsula, the operator has now reported that the work has been successfully completed on wells IC-1 and IC-3.

Well IC-1 is the main producing well in the field and has been worked over in order to repair a defect in the production tubing. The well is now pumping oil and contributes approximately 20 barrels of oil per day ("bopd") (gross) to the field output. Well IC-3 has been dormant for several years, but has now had a PCP (progressive cavitation pump) unit installed and is producing at a gross rate of 5 bopd.

Field production is expected to stabilise at approximately 40 bopd in the next week. LGO receives 50% of this production.

Neil Ritson, LGO Chief Executive, commented: "Although Icacos is only a small part of our portfolio in Trinidad we are delighted that production has now been restored and that the addition of a further well is contributing to the field's profitability."
