In an open letter to Sebi Chairman U K Sinha, he said as per Oil and Natural Gas Corp's (ONGC) own admission, it and GSPC are related parties of the Government of India.
"It is needless to say that there is indeed a strong 'relationship' between the Government of Gujarat that owns GSPC and approved its borrowing binge between 2005 and 2014 and the Government of India that owns ONGC, which suddenly after 2014 seems to have had a realisation that buying GSPC's gas block in KG basin is a virtue. Clearly, this entire ONGC- GSPC deal is an utter sham," he wrote.
"The sanctity and integrity of the venerable 83-year-old institution called the Reserve Bank of India has been demolished following the demonetisation of November 8, 2016. Its credibility has been severely damaged. In this context, it is even more imperative that the 25-year-old institution called Sebi guards its professionalism fiercely," he wrote.
Ramesh said it is incumbent upon Sebi to investigate the ONGC-GSPC transaction on behalf of minority shareholders.
He called ONGC buying Gujarat State Petroleum Corp's (GSPC) 80 per cent stake in the Deendayal block a "Rs 8,000 crore scam".
The Congress leader said GSPC has been trying to recover gas from the KG basin block for more than a decade without much success despite massive borrowings.
"The Comptroller and Auditor General of India (CAG) has issued a scathing report indicting GSPC of incurring massive losses to the exchequer through dubious transactions.
"geographical and geophysical conditions in the KG block have made it a technical challenge to explore and develop. Factors such as low porosity, low permeability, high pressure, high temperature and a tight reservoir make for geological complexities of the kind which has rarely been tackled earlier by any exploration and production (E&P) company in India".
GSPC has spent large sums of money, hired foreign experts and imported sophisticated equipment and yet could not find gas. "Then, why does ONGC deem it fit to pay Rs 8,000 crore to acquire this very block?" he said.
This, he said, is a bewildering justification when the owner of the asset itself claims it is virtually impossible to extract any gas.
"We see limited merit in ONGC's strategy of acquiring these assets. This acquisition may not create meaningful value to shareholders," he quoted investment bank Kotak Securities as saying on ONGC's acquisition plan.
Also, ONGC's cash balance will take a 63 per cent hit for an acquisition that will not add any value.
