In a statement, Pacific Rubiales said preliminary evaluation shows a gross sand interval of 116 feet with a net pay zone of 49.5 feet comprising two reservoir sandstones.

The first interval - at 2955 feet to 2999 feet measured depth - extends the accumulation of the Quifa-5 field to the west, with a net oil pay of 33 feet.

A second, deeper sand interval at 3048 feet to 3071 feet measured depth shows a net oil pay of 16.5 feet, confirming a new discovery within the basal sands.

The company is presently planning to test both reservoirs, and complete the well as a vertical oil producer.

Quifa-8 lies 4.2 kilometres south-west of the Quifa-5 well, which was drilled in November last year and hit 33 feet of net pay.
