ONGC rig upgrade

Vol 14, PW 16 (10 Feb 11) News in Brief

Bharat Heavy Electricals (BHEL) expects to complete a repair and refurbishment programme of ONGC’s onland rig fleet by the end of March.

BHEL tells PETROWATCH the final 12 rigs are being upgraded under a 29-month contract. BHEL’s contract with ONGC began in 2004 and was split into three phases, each lasting 29 months.

“We are in Phase-III,” adds BHEL. “When completed all of ONGC’s land rigs will be as good as new.

” In Phase-I, BHEL upgraded 14 rigs and in Phase-II it upgraded 15 rigs. Under the contract BHEL must take apart each rig for a ‘capital overhaul’.

“The mast and structure are checked,” says BHEL, “and the draw works, electrical motors and instrumentation systems are all changed.” ONGC tells us the upgrade programme, at a cost of around Rs20cr ($4.3cr) for each rig, would extend the fleet’s life by between 10 to 15 years.

ONGC owns 68 land drilling rigs, of which 50 were manufactured by BHEL in the 1980s and 1990s and range from 1000-hp to 2000-hp.
