ONGC Videsh Ltd. (OVL) is testing an oil discovery on trend with its 2017 Mariposa-1 oil strike on Block CPO-5 in Colombia and plans further drilling (OGJ Online, May 5, 2017).
The operator, a wholly owned subsidiary of state-owned Oil & Natural Gas Corp. of India, reported earlier this month that it had logged 284 ft of gross oil pay in the Lower Sands (LS-3) unit of the Cretaceous Une formation in its Indico-1 well. The well encountered pay at 9,833 ft MD and bottomed in Paleozoic rocks at 10,602 ft MD.
Through perforations of a 40-ft interval in the upper part of the LS-3 unit, the well flowed 4,000 b/d of 35.9° gravity oil with 0.3-0.4% bs&w and negligible gas through a 40/64-in. choke. Top-hole pressure was 241 psi.
OVL continues testing the well, which is 6.5 km from the Mariposa discovery, with varying choke sizes.
It plans more exploratory wells and seismic surveys to assess what it calls an “important Cretaceous clastic corridor.”
OVL holds a 70% interest in the block. Petrodorado South America SA Sucursal of Colombia holds 30%.
