Pacific Rubiales Reports Production Potential of 27.7 Mmcf/d

Pacific Rubiales Energy Corp. reported that test results of the DST-1 indicate a production potential of 27.7 million cubic feet per day using half inch choke. These results come from the completion of the short production test at the La Creciente D-1 (LCD-1) well, located at Prospect D of the La Creciente Block in the Lower Magdalena Basin of Colombia. This well was drilled to 10,711 feet True Vertical Depth at Sub-Sea level and it represents a new discovery on a structure independent from the existing producing prospect A.

Commenting on these results, Ronald Pantin, Chief Executive Officer, stated "We are very pleased with this test at Prospect D because it confirms the gas production potential that the La Creciente block has. It has also provided new information to reduce the uncertainty of the geological model of this area to assist in the exploration of the other six prospects located at La Creciente."

The Cienaga de Oro Reservoir consists of 483 feet of well-sorted coarse to fine grain sandstones (upper unit) and an interbedded sequence of silts, shales and fine grain sandstones. This unit was logged by Schlumberger using resistivity, gamma ray and density Logging While Drilling tools. The petrophysical evaluation indicated a Gas Water Contact (GWC) at 10,131 feet True Vertical Depth at Sub-Sea level, 32 feet below the top of the Cienaga de Oro formation. However, the crest of the structure of prospect D is around 9860 feet True Vertical Depth at Sub-Sea level and when confronting it with the depth of the GWC, a gas column width measuring over 272 feet is indicated.
