Petrolifera is making good progress in the drilling of its La Pinta well on the Sierra Nevada I license in the Lower Magdalena Valley onshore Colombia. The well is located 600 meters north of the Guamito 1X well that was drilled in 1975 and tested oil and gas from two separated intervals.
The well spudded on January 23, 2009 and is currently drilling a 12 1/4 inch intermediate hole at a depth of 6,720 feet. The next casing point will be at 8,700 feet where the 9 5/8ths string will be run. The projected final total depth on the well is approximately 13,000 feet.
The well has not encountered any unusual problems during drilling and mud weights remain high with density at about 13.0 ppg due to prevailing high pressure conditions in the subsurface.
