Hindustan Oil Exploration Co., Chennai, has advanced development of Dirok natural gas field in the Assam Arakan basin south of Digboi, India, by letting a $30 million contract to Expro for a modular gas processing plant (OGJ Online, Oct. 30, 2013).
HOEC has reentered three exploration wells in the field and drilled two appraisal wells to develop reserves estimated at 134 bcf of gas. Other drilling is possible.
Production will be from the Miocene Girujan formation. The company says the field has upside potential in Miocene Tipam and Oligocene Barail strata.
It expects the field to produce at a plateau rate of 20 MMscfd for 15 years during a total economic life of 20 years.
Under a lease-operate-maintain agreement, Expro will handle design, engineering, construction, transportation, installation, and commissioning of a plant able to process as much as 35 MMscfd of wet gas.
In addition to the wells and gas plant, development will include a gas gathering station and pipelines connecting those facilities and the field with partner Oil Industry Ltd.'s facilities at Kusijan.
State-owned Brahmaputra Cracker & Polymer Ltd. will buy the gas for transport to its Assam Gas Cracker complex at Lepetkaka via an existing pipeline.
HOEC, operator, holds a 26.882% interest in the license for Block AAP-ON-94/1. OIL holds 44.086%. Indian Oil Corp. Ltd. holds the remainder.
