Pacific Rubiales Prepares More Tests for Colombian Well

Pacific Rubiales Energy Corp. has announced that test results from the La Creciente A-2 ST3 well (LCA-2ST3) in the Cienaga de Oro reservoir indicate a production potential of 29.2 million cubic feet per day using a half-inch choke.   

The maximum static pressure recorded at the well head of LCA-2 ST3 is5,512 pounds per square inch (psi) which is 182 psi higher than that recorded at the LCA-1 well in May 2008. The static reservoir pressure recorded at 11,226 feet true vertical depth is 6,655 psi.   

Comparisons of these pressure levels with those recorded at LCA-1 andLCA-3 after several months of production, suggest that this well may be located in a separate compartment within Prospect A and might correspond with Compartment 2 previously defined with the isopach sandstone trends at the reservoir level. This interpretation will be tested through further pressure and interference tests planned on all producing wells located in Prospect A.   

The company is now preparing to conduct further production tests of an additional 14 foot, potentially producing interval located in the upper zoneof the Porquero Formation at 6,482 to 6,496 feet measured depth (6,246 to6,260 true vertical depth). This is a new pay zone represented by the limestones at the top of the Porquero formation. This interval has 13% porosity and exhibited gas shows while drilling the limestones. The structure at this horizon is fully covered with 3D seismic and displays a well defined four-way closure map. If the test results indicate commercial gas production, it will open an important new exploration target in the La Creciente block.
