– Pacific Rubiales Energy Corp., Toronto, said its Quifa-26X well on 12,950-acre Prospect F in the northern part of the Quifa Block that surrounds Rubiales heavy oil field in Colombia’s Llanos basin cut a gross 65-ft oil column with 41 ft of net pay with 29% average porosity in Carbonera.

Top of Carbonera basal sands was at 2,594 ft true vertical depth subsea. The bottomhole location is 1.6 km from the top of the structure, indicating that the prospect’s maximum hydrocarbon column could reach 108 ft.

Meanwhile, Quifa-31, third appraisal well for the Quifa-7 discovery well on Prospect H, cut a 36-ft gross oil column with an indicated 26 ft of net pay with 29% average porosity. This and other wells extend the total area of Prospect H to 5,175 acres from 4,780 acres. Quifa-31 tested at 415 b/d of 13.6° gravity oil on a progressive cavity pump and will go on extended production test.

The Quifa-23X exploratory well on Prospect G found no hydrocarbons and will be abandoned.
