Reliance Industries' gas field off the Orissa coast holds 2.3 trillion cubic feet of gas reserves, more than double the previous estimates.

International reserve certifier Gaffney, Cline and Associates have put the original gas in place for the six discoveries in Reliance Industries Ltd's block NEC-25 off east coast at 2.3 trillion cubic feet.

In its assessment, GCA had a low estimate of 0.8 Tcf and a high estimate of 5.5 Tcf, said block partner Niko Resources, which hired GCA to complete the review of the NEC-25 discoveries and potential resources associated with undrilled seismic leads.

RIL's prodigious block D6 in Krishna Godavari basin, further down south to NEC-25 in Bay of Bengal, has been certified to contain 11.9 Tcf of reserves from the initial dozen discoveries.

The firm however claims 14 Tcf reserves. GCA's best estimate of original gas in place for the undrilled prospects in the first seismic area in NEC-25 is 1.4 Tcf, with a low estimate of 1 Tcf and a high estimate of 2.7 Tcf.

Upside reserve potential of both drilled and undrilled portion of the block comes to 8.2 Tcf.

Acquisition of 1700 square kilometres new 3D seismic over the prospective area extending south from the original seismic area is now complete and the data is being processed and evaluated, said Niko, which owns 10 per cent in NEC-25 with operator Reliance holding 90 per cent.

 Niko said the findings of the GCA assessment include the exploration results from the six wells drilled by Reliance in the first original 1,800 square kilometres area and include analysis of log, production test and subsurface sampling of 12 separate gas accumulations.

In addition to completing a review of these discoveries, GCA also independently evaluated the range of prospective resources that might be associated with undrilled seismic leads in the first seismic area, it said.
