ONGC continues CPO-5 Block testing onshore Colombia

ONGC Videsh and partners tested the Indico 2 appraisal well in CPO-5 Block in the Llanos basin onshore Colombia and plan additional drilling in 2021, partner GeoPark Ltd. said Nov. 12.

The well was drilled and completed to a total depth of 10,925 ft about 0.8 km northwest and 151 ft downdip of the Indico 1X well, with a net pay of about 161 ft. A test conducted through natural flow in the Une (LS3) sandstone formation resulted in a production rate of 5,500 b/d of oil of 35.2° API, with 0.1% water cut, through a 40/64-in. choke and wellhead pressure of 330 psi.

Additional production history is required to determine stabilized flow rates of the well. Surface testing facilities are in place and the well is already in production.

The drilling rig is moving to the Aguila exploration prospect 4.9 km southeast of Indico field, which will be spudded in late November. Aguila is a multi-target prospect with the Lower Sands (LS3) unit of the Cretaceous Une formation as the main objective (an analogue of existing and producing Mariposa and Indico fields), while also looking for hydrocarbon potential in Guadalupe and Gacheta formations.

Further exploration, appraisal, and development activities are budgeted to continue in the CPO-5 Block in 2021 (mostly in the year’s first half) with drilling of 5-6 gross wells plus the acquisition of 336 sq km of 3D seismic.

ONGC Videsh is operator (40%) in CPO-5 with partners GeoPark (30%) and Petrodorado Energy (30%).
