Colombia: Llanos Mirador oil discovery tested

A unit of Cia. Espanola de Petroleos SA has a heavy oil discovery in an Upper Mirador reservoir at the Melero-1 exploratory well on the Garibay block in the Llanos basin of Colombia. The well is suspended for long-term tests.

Gran Tierra Energy Inc., Calgary, a 50-50 partner with CEPSA in the block, said the Melero-1 went to 9,748 ft measured depth, 9,561 ft true vertical depth, and averaged 922 b/d of 16.8° gravity oil with 0.3% water cut on four drillstem tests in an interpreted 16 ft of net pay.

Elsewhere on the block, the firms spud the Jilguero-2 appraisal well at the Jilguero oil discovery. The joint venture is shooting a further 80 sq km of 3D seismic to help evaluate other structures identified on 2D seismic on the block.
