RIL shuts deep-water gas field in KG basin
D1/D3 gas field, India's first deep-water gas field, ceased to produce on Monday after a $1 billion investment and mammoth technological intervention by Reliance Industries and its partner BP Plc of UK extended the life of dwindling fields by four years, sources said.
New Delhi: D1/D3 gas field, India's first deep-water gas field, ceased to produce on Monday after a $1 billion investment and mammoth technological intervention by Reliance Industries and its partner BP Plc of UK extended the life of dwindling fields by four years, sources said.
D1/D3 field, in Block KG D6 (KG-DWN-98/3) located in the Bay of Bengal, was India's first deep-water gas field to be put on production in April 2009.
Output, which peaked at over 61 million standard cubic meters per day in 2010, had been on a decline as sand and water ingress forced wells to shut down one after the other. While at the peak, it was India's biggest gas field, in the last quarter D1/D3 produced an average of just 1.5 mmscmd.
The sources said only three out of the 18 wells drilled on the fields had remained on production and they too died on Monday.
In perhaps one of its kind interventions in a deepsea field, Reliance-BP, through use of a combination of complex techniques, kept the wells flowing at Dhirubhai-1 and 3 (D1&D3) fields for the last four years.
Reliance had to date made 19 oil and gas discoveries in the Krishna Godavari basin. Of these, D26 or MA -- the only oil discovery in the block -- was the first field to begin production in September 2008.
D1 and D3 fields went onstream in April 2009. MA field cessation expected by September 2018, the sources said, adding the field at its peak had produced 1,08,418 tonnes of oil in May 2010.
MA also started producing gas from April 2009, just when D1 and D6 went live. It peaked to 8.4 mmscmd in August 2010 before sand and water ingress forced shutting down of well after well.
D1 & D3 field too had a peak that year in March when it touched an output of 61.4 mmscmd. KG-D6 produced about 3 trillion cubic feet equivalent, saving about $30 billion in energy imports.
The sources said the field infrastructure would be utilised to bring on stream the next set of fields in the block.
The joint venture has committed $5 billion (Rs 35,000 crores) of investments towards monetising another 3 trillion cubic feet equivalent (about 500 Million Barrels of Oil equivalent) reserves from three projects - R cluster, Satellite Cluster and MJ fields.
