DRILLING: More Kutch wells but GSPC objects

Vol 18, PW 14 (12 Mar 15) Exploration & Production

ONGC is determined to drill "two or three" exploration wells to appraise recent gas discoveries at its GK-OSN-2009/1 and GK-OSN-2009/2 blocks in the Gulf of Kutch despite opposition from partner GSPC.

PETROWATCH learns the Management Committee (MC) of the two blocks is scheduled to meet this month (March) to finalise the work programme and budget for fiscal year 2015-16. A consortium source tells us an earlier MC meeting scheduled for February 27 was postponed because of objections by partner GSPC.

“We don’t know what the problem is," he says. "The block has a gas discovery but GSPC is objecting to the work programme and budget.

” ONGC says it is ready to spend up to $30m on each well if the proposed drilling programme goes ahead. In December 2014 ONGC completed testing a gas discovery at well GKS091-NDA#A, drilled to 4030 metres by jack-up Kedarnath at GK-OSN-2009/1 in water depths of 61 metres, targeting Cenozoic era formations.

Gas was discovered at 1400 metres and flowed 130,000 cm/d during testing. Earlier on November 14, 2014, ONGC announced a gas discovery at well GKS092NAA-1 at nearby block GK-OSN-2009/2, drilled by JT Angel to 4250 metres, targeting Mesozoic era formations.

ONGC announced that an interval at 898-900 metres in the Jakhau formation of the early Eocene era flowed gas at 115,168 cm/d during testing.
