Valeura Energy Inc., Calgary, said that it and partner Equinor have started reservoir stimulation and testing operations on Inanli-1 appraisal well in the Thrace basin in northwestern Turkey. Thrace basin is west of Istanbul and extends to the borders of Greece and Bulgaria.
Valeura, a natural gas producer, said all the required testing equipment was on site. Diagnostic fracture injection testing and extended leak-off tests are scheduled to start within days. Reservoir stimulation is planned for early July.
The plans call for a minimum of four zones to be tested with the Inanli-1 appraisal well. Yamalik-1 was the first deep exploration well in the basin-centered gas accumulation (BCGA) play.
BCGA plays are among the more economically important unconventional gas systems worldwide. They are made up of pervasive, basin-wide gas accumulations trapped in low-permeability rock.
Valeura company has participated in numerous drilling projects throughout the southern Thrace basin since 2013. Play types have ranged from conventional shallow gas exploration prospects in the overlying Danismen and Osmancik formations to the tighter gas prospects in the Mezardere and underlying Teslimkoy and Kesan formations (OGJ Online, Mar. 22, 2016).
