HOUSTON, June 1
-- Petrominerales Ltd., Bogota, said its Capybara-1 exploration well on Castor block in Colombia’s Llanos basin pumped at the rate of 660 b/d of 29° gravity oil with 87% water cut from two intervals in Eocene Carbonera C7.

Petrominerales, a 66% owned subsidiary of Petrobank Energy & Resources Ltd., plans to place the well on long-term production test by the end of June.

The third well of the company’s Central Llanos basin exploration program, Cerillo-1 on the Casanare Este block, reached 9,580 ft measured depth and was cased as a potential oil well based on indications of hydrocarbons while drilling. A completion rig is starting tests.

Logs at Mapana-1 on the Mapache block, the next well in the program, indicate 16 ft of net oil pay in Carbonera C7 and 9 ft in Guadalupe. TD is 8,220 ft.

After casing is set at Mapana-1, the drilling rig will move to Manzanillo-1, next prospect on the Mapache block.

On the Corcel block in the Llanos basin, the Corcel-C2 development is producing more than 3,000 b/d of 21° gravity oil at 20% water cut. The company plans to increase pump speed in the coming week.

The drilling rig is moving to Amarillo-1 and Baco-1, first two of an initial 10 exploration prospects to be drilled in the northeast part of the block. A second rig is to begin drilling the Boa-2 development well by mid-June.
