Canadian firm Trillion Energy International have reported success at their SASB (South Akçakoca Sub-Basin) gas field cluster offshore northwest Turkiye.
Alapli 2 reached 3,258 m TD on 16 July 2023. Mud logging results suggest over 40 m of potential natural gas pay within 6 separate sands in the Akcakoca Member (SASB production zone). Trillion and operator TPAO (51%) are evaluating LWD log data, after which they will run the production casing ahead of perforating for production.
The Alapli 2 well is the sixth well for Trillion in the SASB gas field cluster. The offset Alapli-1 well drilled several years ago tested 7.1 mmcfg/d from a combined three zones with a measured thickness of 15 m. However, the well was not put on production. Most recently, the group drilled Bayhanli-2 well nearby, recording 11.9 mmcfg/d on test from 8 intervals in the same Akcakoca Member.
The SASB cluster is expected to contain 323 BCF GIIP, with 93 BCF net recoverable gas to Trillion. This is expected to increase as the firm drills out the remaining 10 development wells, followed by 10 prospective resource exploration wells within the same cluster.
Further upside may be delivered with new stratigraphic targets in the SASB area and targets in new acreage being negotiated by the firm in northwest Turkiye. The drilling adds to a string of interesting results for this burgeoning gas play, with major discoveries to the north in the Black Sea at Sakarya, and along the coast of Bulgaria and Romania.
