RIL shuts seventh well in KG-D6 gas block
RIL on November 29 shut well B4 on the main producing fields of Dhirubhai-1 and 3 (D1&D3) in KG-D6 block “due to high water cut/sanding issues,” according to a status report of the Directorate General of Hydrocarbons (DGH).
The shutting of the seventh well saw output from D1&D3 fields drop to 19.02 million standard cubic meters per day from about 20 mmscmd a month ago. Together with 4.25 mmscmd from MA oil field in the same block, KG-D6 produced 23.27 mmscmd of gas in the week ending December 2, DGH said the status report dated December 3.
RIL has so far drilled 22 wells on D1&D3 fields but has put only 18 on production so far. D1&D3, which started gas production in April 2009, had touched a peak of 55 mmscmd in August 2010 before beginning of water and sand ingress in wells. It had closed six wells since end-2010 and last month the seventh well was shut. The same problem has held to shutting of one-third of the wells on MA oilfield in the same block. Output from MA is half of the peak rate it had achieved in 2010.
Sources said RIL had last year proposed to do workover or maintenance job to revive sick or closed wells but the oil ministry and DGH
