HOUSTON, Apr. 26
– Calculated absolute open flow rate is revised to 18 MMcfd, up 5.5 MMcfd, at the Petrolifera Petroleum Ltd. Billante SE-1X exploratory well in Colombia’s Lower Magdalena basin.

The upward revision resulted from recovery of the bottomhole pressure data recorded during flow and shut-in periods of a production test run Apr. 17-20, 2010. Data from the production test replaced assumptions used in the earlier estimate.

Measured flow from the well, on the Sierra Nevada license, was 8.4 MMcfd from Cienaga de Oro.
