Meanwhile, Reliance Industries shuts 10th gas well on D1 and D3 fields
27 Nov 2013 11:06 PM GMT
Reliance Industries Ltd (RIL) has shut another well on the main gas fields in the eastern offshore KG-D6 block due to high water ingress, leading to output plummeting to all-time low of 8.73 mmscmd. Reliance Industries Ltd this month shut well number B7 on the main producing fields of Dhirubhai-1 and 3 (D1&D3) in Krishna Godavari basin block KG-DWN-98/3 or KG-D6 due to ‘low pressure and associated high water production,’ according to a status report of the Directorate General of Hydrocarbons (DGH).
B7 is the 10th well to be shut since late 2010 when water and sand ingress made production of gas difficult. Reliance Industries Ltd had last shut A1 well on 2 April this year for ‘reservoir build-up study.’ The latest shutdown led to the output slipping from Dhirubhai-1 and 3 fields to 8.73 million standard cubic metres of gas per day in the week ending 17 November, the report said. Together with 3.32 mmsmcd from MA oilfield in the same block, total output from KG-D6 was 12.05 mmscmd in the week.
Reliance Industries Ltd has so far drilled 22 wells on the Dhirubhai-1 and 3 fields but has put only 18 on production so far. 10 out of these 18 wells are now shut. Like B7, the company has been forced to shut the previous wells due to high volumes of water and sand seeping in, which affected production. It had previously shut well B6, the eighth well to be closed on the Dhirubhai-1 and 3 fields , on 9 January and B4, the seventh well, on 29 November last year.
KG-D6 fields, which began gas production in April 2009, hit a peak of 69.43 mmscmd in March 2010 before water and sand ingress shut down of wells after wells. This peak output comprised of 66.35 mmscmd from the Dhirubhai-1 and 3 fields, the largest of the 18 gas discoveries on the KG-D6 block, and 3.07 mmscmd from MA field, the only oil discovery on the block. Besides the fall in output from the Dhirubhai-1 and 3 fields, gas production from MA field, which had hit a peak of 6.78 mmscmd in January 2012, too has dropped. The report said MA field produced about 4,975 barrels per day of oil from four out of the six wells drilled on the field, during the week ended 17 November.
Of the 12.05 mmscmd of gas production from KG-D6, 11.75 mmscmd was sold to urea manufacturing fertiliser plants. ‘No sale was made to power plants during the period,’ it said. The remaining 0.30 mmscmd was consumed the pipeline that transports the KG-D6 gas, it said. Reliance Industries Ltd , the report said, has projected an output of 11.90 mmscmd in November.
