Two rigs for Bokaro CBM development at ONGC

Vol 19, PW 13 (10 Mar 16) Exploration & Production

Nearly four years after the oil ministry approved its Rs250cr ($37m) development plan, ONGC is finally preparing to drill 140 development wells at its BK-CBM-2001/1 or Bokaro CBM block in eastern Jharkhand state, also home to a dangerous Maoist insurgency.

PETROWATCH learns ONGC will need "at least" two rigs for the drilling programme, expected to begin by the end of this year (2016). An ONGC source at Bokaro confirms it sent a request to the corporate materials management (MM) department in Delhi last month (February) outlining its requirement for two rigs.

"We have submitted all the necessary documents to the MM department after getting approval from our HoD (Head of Department)," he says. John Energy, Greka Drilling and Essar Oilfield Services all confirm to this report that they are interested in participating in ONGC's upcoming two-rig tender.

ONGC believes the drilling programme will help it achieve plateau gas production of up to 780,000 cm/d at the block, sustainable for up to 10 years and estimate the 95-sq km block holds 1.2-tcf of in-place gas reserves. In Phase-I, ONGC and its partner IndianOil drilled eight coreholes and two test wells.

Under Phase-II they drilled 12 'pilot wells' by January 2011. "Of the 12, three are ready to produce but have been capped," says ONGC.

"At present we're not producing any gas." ONGC was earlier producing and flaring 1500 cm/d of 'test gas.'
