Second gas discovery for ONGC in Gulf of Kutch

Vol 18, PW 10 (15 Jan 15) Exploration & Production

ONGC is on a winning streak in the frontier Gulf of Kutch region offshore Gujarat where it will soon announce a second gas discovery.

The first was announced in November, 2014, from its 1242-sq km shallow water block GK-OSN-2009/2. Now it is preparing to announce a second gas discovery at adjacent block: 1264-sq km GK-OSN-2009/1.

At this NELP-VIII block, ONGC completed testing a gas discovery last month (December) at well GKS091-NDA#A after drilling to 4030 metres TD using Great Offshore’s jack-up Kedarnath, targeting Cenozoic era formations. Well GKS091-NDA#A is the first of three Phase-I committed wells and sits in water depths of 61 metres.

"Gas was discovered in a zone at 1400 metres," says a consortium source. "The well flowed around 130,000 cm/d during testing.

ONGC will soon formally announce the discovery." Our source adds that the ONGC-led GK-OSN-2009/1 consortium will need an extension of at least six months to Phase-I, which ends next month (February 2015).

"A letter to the DGH (seeking an extension) will be sent within the next few days," adds ONGC. "We can't complete our MWP (Minimum Work Programme) otherwise.

” ONGC wants a similar six-month extension to Phase-I at its block GK-OSN-2009/2 where it announced the first gas discovery.
