HOUSTON, Dec. 9
-- An exploratory well testing a new play concept on Colombia’s Rio Ariari block in the Llanos basin has tested heavy oil at the rate of more than 600 b/d.

The Mochelo-1 vertical well flowed the 10° gravity oil with 80-90% water cut on a 7-hr test of Eocene Mirador sand, in which logs indicated 69 ft of potential net pay, said Petrominerales Ltd., Bogota.

The company expressed extreme encouragement at the flow rate, said the thick Mirador is expected to be conducive to horizontal penetration, and said it is considering a horizontal sidetrack of Mochelo-1 to optimize production characteristics.

Petrominerales will shoot a further 372 sq km of 3D seismic on the western part of the block to delineate Mochelo and plan commercial development.

The company has spudded Borugo-1, the fifth exploratory well of a planned nine-well program on the block. Borugo also targets a new play concept distinct from the Mochelo-1 and Rio Ariari-1 discoveries.
