BP GAUGES 'SIGNIFICANT' FIND IN COLOMBIA

A combine led by BP Exploration has tested an oil and gas discovery it calls "significant" in the Llanos foothills of Colombia. BP's 2A Cusiana, 160 km northeast of Bogota, flowed a combined 6,680 b/d of oil and 22.1 MMcfd of gas from three pay zones in two formations in a gross hydrocarbon column of about 1,900 ft. Tests of more zones will require several more months. Two intervals in the Cretaceous Guadalupe at 14,100-600 ft flowed at rates of 2,800 and 2,240 b/d of 30-37 oil and 3.3 and

A combine led by BP Exploration has tested an oil and gas discovery it calls "significant" in the Llanos foothills of Colombia.

BP's 2A Cusiana, 160 km northeast of Bogota, flowed a combined 6,680 b/d of oil and 22.1 MMcfd of gas from three pay zones in two formations in a gross hydrocarbon column of about 1,900 ft. Tests of more zones will require several more months.

Two intervals in the Cretaceous Guadalupe at 14,100-600 ft flowed at rates of 2,800 and 2,240 b/d of 30-37 oil and 3.3 and 7.3 MMcfd of gas, both through 1/2 choke.

Eocene Barco at 13,870-14,070 ft flowed 1,640 b/d of 38 oil and 11.5 MMcfd of gas, also through a 1/2 choke.

Stabilized wellhead pressures for the three tests were 1,550, 2,300, and 2,940 psi, respectively.

The strike is on the 278 sq km Santiago de las Atalayas license in which BP owns a 40% interest. Total Exploratie Mij. BV, also holds a 40% interest, while Triton Colombia Inc. owns the 20%.

BP Chairman Robert Horton termed 2A Cusiana "an early but major example" of success in a decision made 2 years ago to shift exploration strategy through an increase in focus on less explored regions of the world, including Colombia.

BP is drilling 1 Buenos Aires, about 5 km south of 2A Cusiana, on the Tauramena license to help assess the extent of the discovery. Tauramena interests are BP and Total 25% each and Triton 50%.

BP also holds 100% interests in the Pauto, Tamara and Sacama license areas, totaling about 2,900 sq km, along a trend north of the discovery license. The company's 1 Tamara is drilling below 10,000 ft.
