ONGC wants KG drilling consultant

Vol 18, PW 22 (02 Jul 15) News in Brief

Expect a tender soon from ONGC to hire a drilling consultant to develop the Nagayalanka oil and gas discoveries at the KG-ONN-2003/1 onshore block in Andhra Pradesh.

The Management Committee of operator ONGC, partner and former block operator Cairn India, the oil ministry and the DGH are planning a meeting on July 7 to discuss the matter. "Nagayalanka is an important project," says an ONGC source.

ONGC wants the consultant to identify a rig to drill 20 planned wells. "All wells will have a horizontal section that will be hydrofracked," adds ONGC.

"We'll need a 3000-hp electrical rig." All wells will be drilled vertically to 4000 metres and horizontally to 1500 metres. "Hydrogen sulphide and helium in the wells will make drilling challenging," we hear.

ONGC expects to encounter pressures up to 9000-psi and temperatures of up to 340-F. ONGC and Cairn will spend $1bn to develop the Nagayalanka discoveries announced by Cairn in April 2012 and November 2011.
