HOUSTON, Feb. 22 -- A stratigraphic well on Hocol SA’s CPO-17 block in Colombia’s Llanos basin has cored oil shows in several formations, said 50% partner Maurel & Prom, Paris.

The first well, drilled to a depth of 864 m, has shown the presence of in situ oil in Basal Oligocene sands.

Hocol recovered 96 m of cores of which 27 m have oil impregnation and 9 m show significant oil saturation. Further analysis is being carried-out to determine reservoir parameters. There were also oil indications during drilling in the C5 and C7 formations.

The work program for this prospect includes more stratigraphic wells and a regular exploration well, Merlin-1, with a main Oligocene objective to allow for possible production testing. Other large prospects have been defined from 680 line-km of 2D seismic shot in 2010.

CPO-17 covers 2,103 sq km 200 km southeast of Bogota between Castilla and Rubiales oil fields. It was awarded in 2008.
