Jubilant Spuds 1st Well in Golaghat Block
Jubilant announced that the exploration well Prospect-16 (P-16-1), located approximately 46km south from Golaghat town in the AA-ONN-2003/1 block of Assam, was spudded on March 20, 2011 by the Quippo rig #4.
This is the first exploration well to be drilled by Jubilant in this 81 km2 block. The vertical well will be drilled to a total depth of 1,660 meters into the basement with the objective of discovering oil bearing sands in the Kopili, Sylhet, Tura and lower Gondwana reservoirs. The well is expected to take approximately 25 days to drill.
This well is part of the minimum work program commitment by the consortium. The joint venture is committed to drill 6 additional wells as part of the Phase-1 Production Sharing Contract (PSC) commitment. The execution of the remaining work program will be finalized on obtaining forestry land approval for its remaining locations.
Previously, three wells were drilled by Oil & Natural Gas Corporation Limited (ONGC) on this block; one of which had shows of oil and gas from multiple reservoirs. The prospect is a fault bounded closure of about 2 km2 and is located approximately 12km north-west from the recent ONGC discovery, Kasomarigaon-2, that tested at 604 bopd and around 400 Mscfd from the Bokabil formation.
The Best Estimate of gross prospective resource, as certified by Gaffney, Cline & Associates (Consultants) Pte. Ltd, in the CPR dated 22nd November 2010, is 6.6 mmbls with a geological chance of success estimated by the consortium of 14%.
