GSPC about to begin Deen Dayal West drilling

Vol 15, PW 5 (08 Sep 11) Exploration & Production

GSPC is gearing up to begin a three-well development drilling programme at the Deen Dayal West gasfield this week.

PETROWATCH learns GSPC wants to spud Deen Dayal West development well DDW-D-1 using Chennai-based Aban Offshore jack up Deep Driller-1. Hired in March 2010 at $112,000/day, Deep Driller-1 moved to Deen Dayal West last month (August) after drilling a ‘dry’ appraisal well to 5621 metres TD at Deen Dayal East between April and June this year.

GSPC is hoping for better luck at Deen Dayal West where it plans to drill each of the three proposed development wells to TD of around 6500 metres. “Monsoon rains in the eastern offshore don’t usually end before October 1,” explains a senior GSPC source.

“But we are experiencing a spell of unusually fair weather and hope to spud the first development well soon.” Deep Driller-1, he adds, will drill all three proposed development wells from the six-legged Deen Dayal West wellhead platform, which has 16 ‘production well’ slots and sits in water depths of 60 metres.

Larsen & Toubro completed the installation of this well-head platform on May 28 under a contract won in April 2010. Weighing 3602-tonnes and standing 217-feet tall, the well-head platform was shipped to Deen Dayal West by L&T from Malaysia this April aboard a large-sized barge.

“The barge took 14 days to transport the platform to Deen Dayal West’s KG-8 location,” adds GSPC. “L&T launched and ‘up-ended’ the ‘jacket structure’ on April 20 and drove sixteen ‘piles’ into the seabed to provide structural stability.

” GSPC wants Deep Driller-1 to drill the three wells by mid-November, when a ‘modular rig’ hired from Houston-based Nabors Drilling is expected to mobilise at Deen Dayal West.
