High hopes for Dayalpur at Jorhat

Vol 20, PW 7 (15 Dec 16) News in Brief

More good news from ONGC's newly-created Jorhat Asset in Assam where testing of the Dayalpur discovery was completed in early December.

ONGC believes it can begin commercial production of 750 b/d by end-December from the well which can be ramped up to 3000 b/d within a year. On December 6 a Jorhat team met ONGC director onshore VP Mahawar to discuss a proposal to develop Dayalpur by drilling eight delineation wells.

"We're planning to hire a 2000-hp rig for three years," says ONGC. "The proposal was sent to management for approval in November.

We want a fast-track tender." ONGC drilled Dayalpur to 3000 metres using its own 2000-hp land rig E-760, still at location. ONGC tested the Tipam, Bokabin, Barail, Kopili, Sylhet and basement formations.

"Dayalpur has the potential to produce 50-100 tonnes (750 barrels) of oil from each of the six zones tested," adds ONGC. "Kopili produced 70,000 cm/d of gas during testing.

Such production potential from a single well is rare." Jorhat, carved out in May 2016, is producing 3000 b/d of oil.
