GSPC wants two rigs for four wells at 3 blocks

Vol 20, PW 6 (01 Dec 16) Exploration & Production

GSPC's future might look uncertain with unsubstantiated rumours of an ONGC takeover imminent but for now it's focusing on hiring two rigs for three Cambay basin blocks beginning March 2017.

GSPC wants one 100-tonne workover rig and one 180-200-tonne drilling rig for intervention jobs at three completed wells and to drill one new well. At Ahmedabad block CB-ONN-2000/1, GSPC wants to sidetrack well PK-1 from 800 metres to 'fish out' a stuck pipe.

Originally completed in 2003, the PK-1 discovery is estimated to hold 10m barrels of oil and 300bn cubic feet (8.5bn cubic metres) of gas. At pre-NELP Tarapur block CB-ON/2, GSPC wants to carry out packer retrieval and perforation jobs at well TA-6A7.

At Ankleshwar block CB-ONN-2003/2, GSPC needs to clean out the wellbore and carry out a recompletion at the Ank-41S gas well before installing a liner. This well was completed to 2388 metres in May 2010 but the production casing only landed to 1752 metres.

This block will also see GSPC drill a fresh well tentatively called Ank-41SA1 to 2500-metres. Who will win the rig contracts? GSPC held a drillers meeting on November 8 but declines to disclose who attended.

"We're negotiating," answers a GSPC source curtly. On November 23 meanwhile oil minister Dharmendra Pradhan buried rumours of an imminent ONGC takeover of GSPC with a brief statement to parliament.

"There is no proposal to acquire GSPC by ONGC," he said.
