New Delhi: As the Oil Ministry readies to take action against Reliance Industries for the fall in output from the KG-D6 gas fields, the Mukesh Ambani-led firm has warned that any attempt to limit cost-recovery is illegal and will be challenged in court.

The ministry and its technical arm, the DGH, are upset with RIL because production from the Dhirubhai-1 and 3 (D1 and D3) gas fields in the prolific KG-D6 block has fallen from 61 million cubic metres per day in March, 2010, to about 37 mmcmd, instead of rising to 61.88 mmcmd, as projected by the company when it got its USD 8.8 billion capital expenditure plan for development of the field approved in 2006.

The ministry has attributed the fall in output to non-fulfillment of RIL's commitment to drill 22 wells in the field.

RIL has so far spent USD 5.694 billion on the two fields and has recovered USD 5.258 billion from the sale of gas produced.

However, the ministry wants to limit cost recovery in the block in proportion to the slippage in output vis-a-vis the stipulated timeline, reducing RIL's entitlement to USD 3.405 billion.

The firm however feels such a move would be ultra vires, or beyond the ministry's powers, as the Production Sharing Contract (PSC) does not have any such provision and the USD 1.85 billion already recovered by RIL cannot be reversed.

"If the PSC were indeed to be re-written to link cost recovery to levels of production, it would also have to include provisions for allowing the contractor (RIL) to recover costs in excess of his investment in case he were to achieve a rate of production higher than that estimated at the time of capex approval," RIL Senior Vice-President (Commercial) B Ganguly wrote to the ministry on September 16.

RIL said production below the original estimates meant the company loses its right to recover its investment within the originally estimated timeframe, causing huge losses in terms of sunk capital. Besides, RIL has already suffered huge erosion of market cap due to news of the fall in production.

RIL said as per the PSC, all costs and production numbers provided in the field development plan (like the one approved for KG-D6 in 2006) are only estimates based on the understanding of the reservoir and the market prices at any given point of time and "such estimates cannot be construed as constituting a commitment under the PSC."

KG-D6 wells did not perform as per the FDP, as a severe drop in reservoir pressure and acute water ingress has already forced closure of two out of the 18 well drilled so far.

The Initial Field Development Plan (FDP) for the D1 and D3 gas fields in the KG-DWN-98/3 block (KG-D6) envisaged a capex of USD 2.47 billion at a peak production rate of 40 mmcmd from 14 wells.

Subsequently, RIL submitted an addendum saying the size of the gas reserves was twice the estimate of 5.32 tcf in the initial plan, at 11.3 trillion cubic feet. It proposed a USD 8.835 billion capex over two phases and envisaged a peak output of 80 mmcmd from 31 producing wells by April, 2012.

Commercial gas production from the D1 & D3 fields commenced from April 1, 2009. RIL in December, 2009, tested its field production facilities at their full rated capacity of 80 mmcmd, during which time an average gas rate of 77-80 mmcmd was maintained for a brief period of three days.

Subsequently, the gas production rate was maintained at 57-61 mmcmd for a four-month period (January, 2010, to April, 2010).

Subsequently, the gas production rate has gradually declined and the current rate is about 37 mmcmd, as against the approved FDP rate of 61.88 mmcmd for the year 2011-12.

RIL says the gas production rate will remain in the range of 40-38 mmcmd, as against the projected peak of 80 mmcmd, till mid-2013 and also that no new well will hooked up to production facilities till mid-2013/14.

The ministry claims that the DGH has repeatedly asked RIL to comply with the approved FDP work programme by drilling two more wells and connecting two other wells to its production system by the first quarter of 2011-12 fiscal. It asked RIL to drill another nine wells by March 31, 2012.
