Solana gauges oil in Colombia's Llanos basin
By OGJ editors
HOUSTON, Oct. 10 -- Solana Resources Ltd., Calgary, reported an average flow of 5,645 b/d of 41° gravity oil from the Tertiary Carbonera formation at a discovery in eastern Colombia's Llanos basin.
Los Aceites-1, on the 16,640-acre Guachiria Block, has permeabilities in excess of 3 darcies, and the flow rate was achieved with less than a 15% drawdown, "indicative of significant incremental flow potential," the company said. Carbonera was perforated at 6,874-84 ft. TD is 7,108 ft measured depth.
The company gauged the flow on a 98/64-in. choke with 75 psi tubinghead pressure. The well produced only 4 bbl of water in 48 hr.
In anticipation of pending government approval of an extended test, Solana plans to build centralized permanent facilities at the nearby Primavera-1 location, site of the company's other 2008 discovery on the block. Oil will be trucked in the short term.
The company, which is remapping the area as a result of the exceptional flow rate, said one more well may be required in the field.
Solana is operator with 100% working interest. Lewis Energy Colombia holds a 30% beneficial interest in the block, and Colombia's state Ecopetrol has a 13% overriding royalty interest that is applied after government royalties.
