GSPC has hired Gaffney Cline & Associates to design a development plan for its Deen Dayal gasfield at eastern offshore shallow water exploration block KG-OSN-2001/3.

PETROWATCH learns GSPC managing director DJ Pandian and general manager planning and development MY Farooqui travelled to London early this month to discuss with GCA executives the outlines of the mandate to prepare the development plan. In due course it’s understood GCA will be given the final FEED (Front End Engineering and Design) report from consultant Worley, plus well data analysed by consultant Petrotel and other geological and geophysical data to help it prepare the development plan.

GSPC wants the development plan to cover production from the PT-12 fault block, which measures less than 20-sq km and where GSPC has drilled four wells. The first was discovery well KG#8, followed by exploration wells KG#17 and KG#15.

This was followed by appraisal well KG#28. Of all the wells drilled on the block, GSPC believes KG#15 was the best, recording a flow rate of 15m cf/d during drill stem tests.

After that was appraisal well KG#28, with 12m cf/d flow rate followed by discovery well KG#8 with 11m cf/d. Well KG#17, with 5m cf/d flow rate and between 500 and 700 b/d condensate came last.

Worley’s preliminary FEED report suggests GSPC construct a wellhead platform that can accommodate a modular drilling rig. Worley has also suggested that only a minimum amount of processing is needed at the platform and that the extracted fluids should be processed at the proposed shore facilities at Yanam.

GCA’s development plan will also incorporate a 20-km pipeline from the platform to shore facilities. GSPC expects the development plan to be ready by March this year, by when it also expects to receive DGH approval of the Declaration of Commerciality for discovery well KG#8.

All being well, GSPC should tender for the offshore platform in June. First gas to shore is expected towards the end of 2010.
