HOEC ready to produce after Dirok-1 workover

Vol 19, PW 24 (11 Aug 16) Exploration & Production

Eight years after it made its Dirok-1 gas discovery HOEC is finally preparing to begin production at its AAP-ON-94/1 block in Assam.

In late-July HOEC converted the Dirok-1 discovery well, originally drilled in January 2008, to a producer, reports a company source. "The well is ready," we hear.

"It will be put on production after the gas sale agreement is signed." HOEC is targeting to initially produce 600,000 cm/d of gas and 500 b/d condensate and to sell the gas to Oil India and the Brahmaputra Cracker and Polymer complex at Lepetkata. HOEC is using Essar Oilfield's 1500-hp rig, which is a National 110-UE model, hired at $25,000/day since January this year (2016) for the Dirok-1 workover.

Dirok-1 was completed using 9500 metres of 13 3/8-inch casing and also used 9 5/8-inch casing. An HOEC source clarifies that it is actually producing from 3 ½-inch tubing at 1700 metres.

HOEC is now mobilising the Essar rig to start workover at the Dirok-2 discovery, originally drilled in 2010. "Rig up is underway," confirmed HOEC on August 8.

Workover and completion of Dirok-2 to 1700 metres will take around 25 days. Next HOEC will ask Essar to drill new well Dirok-5 five-km from Dirok-2.

"The depth of Dirok-5 will be within 3000 metres," we hear.
