HOUSTON, July 29
– Petrolifera Petroleum Ltd., Calgary, said the La Pinta-1 well on the Sierra Nevada license in Colombia’s Lower Magdalena basin sanded up shortly after flowing at the rate of 776 b/d of 44° gravity oil with limited associated gas.

The temporary flow came from perforations at 10,695-720 ft near the top of the Cienaga de Oro formation and is not reflective of sustainable performance, the company said.

A coiled tubing unit tried to clean out the sand plug but had to desist because it encountered pressures estimated at up to 8,000 psi below the plug. Other evidence indicates the well may have suffered a casing split or separation below the perforated interval.

Petrolifera Petroleum released the well to another operator to drill one well after which it will return for further exploratory drilling, likely on the Sierra Nevada license, which the company anticipates renewing for one more year. A renewal requires shooting 150 line-km of 2D seismic and drilling one exploratory well.

The company may consider farmout out part of its 100% interest in the block.
