JKX Oil & Gas said that the Shkorpilovtci South West R-01 exploration well, on the B1 Golitza licence in east Bulgaria, has been drilled to a total depth of 837m.

Significant gas shows were encountered during drilling of the primary target, the Avren Formation, and the underlying secondary target, the Dvoynitca Formation sandstones.

Wireline log data demonstrated that in this location the primary reservoir was marginal to the main depositional system.

The highly laminated underlying secondary reservoir was also determined to be water wet.

The well has now been plugged and abandoned, and the shallow depth to target precluded an optimal geological sidetrack at this time.
