After Reliance now GSPC plans KG field development

Vol 12, PW 22 (09 Apr 09) Exploration & Production

Far away from the limelight, GSPC is quietly preparing a development plan for its hydrocarbon discovery at KG-OSN-2001/3, not nearly as significant as Reliance’s D6 discovery, which began producing at midnight on April 1, but significant nonetheless.

By next month (May), GSPC is confident it will have a development plan ready for submission to the DGH, following oil ministry approval in December of a â€کDeclaration of Commerciality’ for the Deen Dayal (West) discovery on the PT-12 fault block, with a DGH-endorsed figure of 0.9-tcf of gas in-place. Work to identify drilling locations for the proposed development at Deen Dayal (West) is underway with GSPC shooting a $40m seismic survey across the area using Western Geco boat Geco Searcher.

“Western is using (state-of-the-art) Q-Marine technology for this shoot,â€‌ we hear. “It will have a surface coverage of 470-sq km and when â€کfully migrated’ will cover more than 250-sq km.

â€‌ Elsewhere on the block, exploration continues apace. Last week, GSPC began the first of eight Drill Stem Tests (DSTs) planned at the promising exploration well KG#21 (see above) drilled by Saipem jack-up Perro Negro 3, west of the Deendayal (West) discovery.

“KG#21 is on a different fault block to Deendayal (West),â€‌ says a source, “Here GSPC is having a problem of plenty. This is the largest number of DSTs at any single well out of the 11 wells so far drilled on this block.

â€‌ The same can’t be said for KG#32. On March 23, GSPC released jack-up Deep Driller-1 after it had completed the well.

GSPC’s third well KG#19 caused a stir last month when the 8 آ½-inch hole drilled by semi-submersible Essar Wildcat encountered a â€کkick’ while drilling from 4313 metres to 4450 metres. But the â€کkick’ was successfully controlled using a 14-ppg-mud weight and the section drilled to 4562 metres.
