Pacific Stratus Completes Tests at La Creciente 3 Well

Pacific Stratus has completed the first production test at the La Creciente 3 well (LCA-3), located at Prospect A of the La Creciente Block in the Lower Magdalena Basin of Colombia.

This well was drilled to a final measured depth of 12,950 feet or 10,977 True Vertical Depth at Sub-Sea level. Test results of the DST-1 indicate a production potential similar to that measured at the LCA-1 well. Gas samples have been sent to laboratories for definitive analysis of quality and calorific value.

Due to high pressures encountered during drilling, the company decided to run and cement the production liner to eliminate potential operational risks of testing the well as an open hole.

Actual production may differ from initial test results. The second production test (DST-2) will commence after the company runs a Vertical Seismic Profile log inside the borehole and those results will be announced as soon as completed.

As part of the evaluation of LCA-3, the company has hired Schlumberger Ltd. to carry out a reservoir modeling study to analyze and compare production results between LCA-1 and LCA-3.

The Cienaga de Oro Reservoir consists of 630 feet (true thickness) of well-sorted coarse to fine grain sandstones of which the upper zone consists of 257 feet of gas-bearing sandstones. This unit was logged using resistivity, gamma ray and density Logging While Drilling tools. The petrophysical evaluation reported 219 feet of net reservoir sandstones, a net to gross ratio of 85%, an average porosity of 15.5% and an average water saturation of 27.3%.

The Saxon 126 Rig that was recently overhauled has moved to Prospect D at La Creciente and will spud the LCD-1 well on October 26, 2007.
