Block Energy PLC (LON:BLOE) has completed drilling its sidetrack well at West Rustavi in Georgia.
WR-38Z went to a depth of 2,634m with a horizontal section of 646m into field's primary oil-bearing Middle Eocene formation.
Following the experience from the previous appraisal well (WR-16a), Block will use swellable packers to guard against possible fluid incursion from formations beyond the targeted Middle Eocene zone.
WR-38Z is the second in the multi-well programme underway at West Rustavi.
The company plans to sidetrack three other wells and is currently acquiring a 3D seismic survey to help its understanding of West Rustavi's subsurface to aid future target selection.
Paul Haywood, Block's chief executive, said it would release the WR-38Z flow results as soon as it is able.
