After completing the first phase of the rehabilitation program for a gas field off the coast of Turkey, the Canadian oil and gas company Trillion Energy is preparing for the second phase in order to maintain its natural gas production in the long term.
Trillion says the completion of four workovers is a key milestone in its strategic perforation program and increases the gas production capacity of its SASB field in the Black Sea offshore Turkey. The last update on the two-month work program was provided on July 31.
As the Canadian company reports, the full payback of the recent perforation investments was achieved within 35 days of production. The wells began production in staggered fashion from July 9 to 28 and have already produced 140 MMcf.
Arthur HalleranCEO of Trillion, said: “Drilling on the Akcakoca platform has been successfully completed and gas production and WHP continue to increase. This early return on our investment is a clear indication of the field’s robust production potential. The results are very positive and give us good indications that reducing the production tubing size from 4 ½ inches to 2 3/8 inches using velocity lines should stabilize gas production at targeted levels.”
In the first phase of the overhaul, all remaining gas reserves on the Akcakoca platform were perforated, including three long-range, deviated gas wells – Guluc-2, South Akçakoca-2, West-Akçakoca-1 – and the completed legacy Akcakoca-3all practiced in the 2022/2023 program.
Two wells have stabilized: South Akcakoca-2 with approximately 2.75 MMcf/d after 36 days of production and Guluc-2 with an average of 2.0 MMcf/d after three weeks, with production currently stable at approximately 1.25 MMcf/d. As for the other two, West Akcakoca-1 has produced an average of 0.60 MMcf/d over two weeks but has not yet stabilized due to some anomalies. At Akcakoca-3, there was no initial gas flow after perforation, but the wellhead pressure (WHP) has steadily increased from 100 psi to 478 psi, so production is expected to begin soon.
Gas production from the Akcakoca platform has averaged 4.6 million cubic feet per day since the completion of the perforation program. With Phase 1 of the SASB work program completed, the Company is preparing for the next phase of installing velocity lines in 8-9 existing gas wells. The goal of this initiative is to increase and sustain natural gas production over the long term.
