Arpatepe

Until the late 2007s, the prevailing view about Ordovician Bedinan sandstone play was it’s having limited areal extends from some small oil fields along the southern foreland area. In 2008, AME led JV group discovered oil in Arpatepe prospect. It is the first Paleozoic oil field in the country. Within the following years, many other operator companies actively exploring the Paleozoic plays in the area made several oil field discoveries in various sizes. The Diyarbakır Basin still bears the biggest Paleozoic HC potential in a large unexplored area.

Since there are not any viable structures could be mapped at Mardin reservoir level, this play has not been considered as the main target within the Arpatepe license area.

Arpatepe-1 tested 41 API oil in 35 m gross reservoir interval of the Bedinan quartz-rich sandstone member (B4), and the well was put on production with 350 bopd with natural flow.

In 2009, 252 km2 3D survey was caried out for better well placement for both exploration and development phases. In this region, seismic quality is usually good for even identifying subtle structures at Paleozoic reservoir levels.

Within the exploration phase and period of field development afterwards, seven more wells drilled along the same Arpatepe fault closure. There is a total of four wells currently producing from the Bedinan sandstones.

The Arpatepe wells usually start at a rate of 250-350 bopd with natural flow if both two sands are open and artificial lifting is required later when the production rate drops below certain economic limits. Arpatape-1 production has been increased as much as 60% after installing a sucker-rod pump in the well.

North Arpatepe-1 well was spudded in June 2022 to test for any commercial oil accumulation in the Bedinan sandstones in a separate basement fault closure 2.2 km to the North of the Arpatepe field. The well didn’t reach to its planned TD due to technical reasons and temporarily abandoned in Dadaş formation.
