Vol 2, PW 23 (09 Dec 98) Exploration & Production

It has been an encouraging few months for Oil India Limited (OIL), the countrys junior oil explorer.

Petrowatch can confirm a newspaper report which appeared on 30 November of three major commercial discoveries made by Oil India this year. A senior source at Oil India confirms that the discoveries were made in the following structures in Assam: Mohanbari; North Balijan and South Kathaloni.

A new reservoir has also been located in the Hapjan structure and in the southern block of the already discovered Tamulikhat structure. Last year, OIL had a similar run of good luck with the following five commercial discoveries: Deohal Structure, close to Naharkatiya field; Bhogpara structure, west of Dikom field; Sapekhati structure, southwest of Shalmari structure; Jeraipathar structure near Chabua; and Tamulikhat structure, to the east of Kathaloni.

However, news from OILs exploration programme on the North Bank of the Brahmaputra river in Assam is less encouraging. OIL has had to postpone indefinitely plans for a two-well drilling programme at Majuli Island - the largest river island in the north-east - because extensive flooding has made the logistics of transporting a rig to the site impractical.

OIL has already drilled three unsuccessful wells on the North Bank but remains confident that proven oil and gas structures on the south of the Brahmaputra extends north across the river. OIL is in the process of evaluating data recovered from the three wells drilled so far.
