ONGC sees early success with Jorhat wells

ONGC is on a mission to increase oil production in north-east India, if you go by the pace of work at its newly carved-out Jorhat asset in Assam.

By end-November ONGC wants to begin development following two oil discoveries made since the new asset was created in May this year (2016). First is an 18-development well and five sidetrack well programme beginning with sidetrack well Khoraghat-38 at the Khoraghat field, near a village of the same name with a population of around 1500, a literacy rate lower than the rest of Assam.

Khoraghat-38 will be drilled to up to 3000 metres TD by an ONGC rig. Another ONGC rig will be brought in from neighbouring Nazira for some of the development wells which will be drilled between 2000 and 3500 metres TD.

A third rig might be hired. In October ONGC invited offers for a series of oilfield services needed for the programme to meet the Mission-600 target to hit Jorhat production of 4200 b/d (600 t/d) over the next 30 months.

"We must reach our target!" says a senior ONGC source. "We're working towards it." He adds the company made two new discoveries this year - Dayalpur, named for a nearby village in Assam's Golaghat district; and Suphayyam, which sits in the eponymous Suphayyam block near the Nagaland border.
