The first interval (2955′- 2999′ MD) extends the accumulation of the Quifa-5 field to the west, with a net-oil pay of 33 feet and average porosity of 31%. A second, deeper sand interval (3048′-3071’MD) with a petrophysical evaluation shows a net-oil pay of 16.5 feet with 32% average porosity. This deeper interval effectively confirms a new discovery within the basal sands. Both intervals show oil-water contacts at 2,999 feet and 3,071 feet MD, respectively. The company is presently planning to test both reservoirs, and complete the well as a vertical oil producer.
The Quifa-8 well is located 4.2 kilometers southwest of the Quifa-5 well drilled in November 2008, which showed 33 feet of net pay. The Quifa block is an exploratory block that almost completely surrounds the Rubiales field in which the company holds a 60% interest in association with Ecopetrol S.A. (40%). The Quifa contract gives Pacific Rubiales Energy the right to develop any discovery until 2031. This block is three times larger than the Rubiales field and has seven additional prospects that have been identified with the interpretation of the recently completed seismic campaign.
