Pan Orient Energy Corp., Calgary, said a well in an undrilled fault block in L53 D East field in Thailand has found the first good quality oil pay of significant thickness in five sandstone intervals.
The L53-DC1 appraisal well, drilled to 1,661 m measured depth, 934 m true vertical depth, highlights the potential of these sands as primary reservoir targets in adjacent undrilled fault compartments, the company said. It is the first of a planned five-well program on the L53 concession.
L53-DC1 encountered 55 m true vertical thickness of net oil pay in six sandstone reservoir intervals based on the interpretation of a full suite of open hole wireline logs, mud log data recorded while drilling, and offsetting well data.
The well encountered oil pay in the A4, A3, A2, and A1 sandstone zones and two shallower sandstone intervals above A1. All oil bearing sands appear to be oil charged throughout, with no evidence of any oil water contact in any sand. This is the first good quality oil pay of significant thickness encountered in the A3, A2, A1, and shallower sandstone zones.
The company is running casing and plans to perforate the A4 sandstone and place the well on production in 3-4 days.
It will then skid the rig to the adjacent cellar and drill L53-DC2, twin to L53-DC1, planned to encounter the A3, A2, and A2 sands structurally higher than in L53-DC1. L53-DC2 is projected to 1,300 m TVD, or 376 m deeper than L53-DC1, to test deeper sandstone targets also located in this untested fault compartment.
