Firms plan $1bn infusion in Panna-Mukta & Tapti fields

09 May 2011 Evaluate

BG India, Reliance Industries (RIL) and Oil and Natural Gas Corporation ONGC) plan to invest at least $1 billion to arrest the fall in production from Panna-Mukta and Tapti (PMT) oil and gas fields off the country’s west coast. BG India, the operator, will seek permission from the Directorate General of Hydrocarbons (DGH). The aim is to increase production by injecting water. This could increase production by 7 per cent. ONGC holds 40 per cent in the field. BG and RIL hold 30 per cent each.

The consortium is seeking an extension of the production sharing contract (PSC) by at least five years to make the investment viable. The PSC is expiring in 2019. The production has been declining at a rate of 18 per cent a year. The current level is 32,000 barrels oil per day and 11.5 million standard cubic metres gas per day. It would require an investment of $1-1.5 billion to increase production by a few million barrels. The process will entail installation of a platform, drilling of wells for injecting water and laying pipelines. The technique involves injecting water back into the reservoir to increase pressure and production. Generally, around 30 per cent oil in a reservoir can be extracted. Water injection helps maintain production over a longer period.
