'Highly prospective' Tripura focus at ONGC

Vol 17, PW 25 (31 Jul 14) Exploration & Production

Rugged terrain, a violent separatist movement, and historically low gas demand - enough to ask why ONGC wants to spend time shooting 250-sq km 3D in northeastern Tripura Yet ONGC wants bids by September 5 from contractors interested in the 3D job, which one bidder estimates to be worth Rs125cr ($21m).

Lodged between Bangladesh and Myanmar, Tripura is 'highly prospective,' believes ONGC. "We find gas in one of every two wells drilled,” he says.

“The world average is one in three.” ONGC expects to raise production in Tripura from 3.5m cm/d to 5.1m cm/d by end-2014 with additional production from the Kunjaban, Sunderban, Sonamura and Rokia fields.

Another 1.5m cm/d is expected from the Baramura block. “We’re already producing 500,000 cm/d from the Baramura South field,” adds ONGC.

“But now we want to do a blanket survey for Baramura North and Baramura South.” ONGC also believes the market for gas is picking up in Tripura because of upcoming power and fertiliser plants like ONGC’s own 726-MW gas-fired power project at Palatana where the 363.3-MW Phase-I was commissioned on December 31 last year.

Also the 101-MW Monarchak power plant in west Tripura owned by North-Eastern Electric Power Corporation is due for commissioning by December 2014.
