Reliance Industries has reported natural gas output at its eastern offshore KG-D6 fields dropping to 31.5 million cubic meters per day this month as high water and sand ingress led to shutting of 8 wells.
Gas output from KG-D6 in the week ended June 3 dropped to 31.57 mmcmd from 32.66 in May,according to a status report filed by the company with the Oil Ministry.
RIL said six out of the 18 wells on the Dhirubhai-1 and 3 (D1&D3) gas fields and two of the six wells on MA oil field in the KG-DWN-98/3 or KG-D6 block in Bay of Bengal were shut due to high water and sand ingress,leading to lower output.
KG-D6 had produced 33.89 mmcmd in April and 34.62 mmscmd in March.
Production from D1&D3,the largest among 19 oil and gas finds RIL has made in the Krishna Godavari basin KG-D6 block,slipped to 25.56 mmcmd during May 28 to June 3.
Together with 6.01 mmcmd output from MA oilfield in the same block,KG-D6 produced 31.57 mmmcd during the week ending June 3.
The KG-D6 output has fallen since hitting peak of 61.5 mmcmd in March 2010 as RIL shut wells after water and sand ingress.
During the week under review,a “total of 12 wells were on production and 6 wells (A2,A6,A10,B1,B2 & B13) were kept closed due to high water cut/sanding issues,” the report said.
The output from KG-D6 is short of the 70.39 mmscmd-level (61.88 mmscmd from D1 and D3 and 8.5 mmscmd from the MA field) envisaged as per the field development plan approved in 2006.
While Reliance holds 60 per cent interest in KG-D6,UK’s BP Plc holds 30 per cent and Niko Resources of Canada the remaining 10 per cent.
The report said two out of the six wells on MA field had to be shut due to water loading.
