When contacted, the Bombay Stock Exchange spokesperson declined to comment on the ONGC matter. The National Stock Exchange spokesperson did not respond to an email query. The Shah report, quoting the Directorate General of Hydrocarbons (DGH), said ONGC acquired and processed its own data in 2006-07 for the Godavari block overlapping Reliance's KG-DWN 98/3 block and conducted a third-party study for the appraisal plan for the block, which it submitted to the DGH in October 2007, and which indicated the continuity of Pliocene channels from ONGC's block to RIL's block. "However, ONGC never raised any allegation regarding the possible continuity of Pliocene reservoirs for a period of more than six years, ie from at least 2007 to 2013. Ideally, according to the DGH, ONGC should have carried out pressure tests in its blocks once RIL commenced commercial production in April 2009 to confirm the suspected connectivity," the report said.
