As Canada’s oil and gas player Trillion Energy has completed the planned perforation operations at its gas field off the coast of Türkiye, it is now anticipating a ramp-up in gas production once it wraps up the installation of velocity strings.
The Canadian firm’s update relating to a two-month work program taking place at its SASB natural gas field in the Black Sea offshore Türkiye, provided on July 30, indicates that the remaining three perforation intervals totaling 4 meters have been perforated at the West Akcakoca-1 well, for a total of five zones.
Following previous updates in this regard shared on July 24 , July 17 , and July 8 , the firm has now underlined that delays resulting from inclement weather and waiting for spare parts to arrive have been overcome and the perforation program is complete.
Trillion’s CEO, Arthur Halleran , noted: “We have now perforated all remaining gas pay in the SASB wells. We are pleased with the results. Installation of production tubing in the past required a jack-up rig which was extremely expensive. However, we intend to run the new production tubbing without a rig using a snubbing unit, which is substantially cheaper and will provide a long-term production solution.”
According to Trillion, the initial two perforated zones at West Akcakoca-1 comprising 5 meters of gas pay increased the wellhead pressure (WHP) from 1150 psi to 1350 psi, reaching 1694 psi in the subsequent three zones. West Akcakoca-1 is now producing 2.8 MMcf/d using a 28/64 choke to prevent its high pressure from backing out other wells.

The Akcakoca platform’s West Akcakoca-1, Guluc-2 , and South Akcakoca-2 wells combined are said to be producing a total of 7.3 MMcf/d, in which Trillion has a 100% stake. The firm foresees an increase in production following the installation of new tubing – velocity strings – anticipated to happen soon.
In May, the Canadian player said that around 16,500 meters of velocity strings, new well heads, and other tangibles were ordered and received at the shore base near the Akcakoca port. The gas velocity strings are expected to improve well performance for long-term stabilized production as they restrict the amount of water entering the tubing to prevent water loading.
