Reliance Gets Rs 24,500 Crore Demand Notice For Producing Gas From ONGC Block

The government has slapped a USD 2.81 billion (about Rs 24,500 crore) demand notice on Reliance Industries Ltd and its partners, including BP Plc, for gains made from producing and selling natural gas that may have migrated from neighbouring block of state-owned ONGC.

This follows the Delhi High Court's decision on February 14, overturning an international arbitration tribunal ruling that held the duo not responsible for paying any compensation for the gas they produced and sold which had allegedly migrated from adjoining fields.

"Consequent upon the Division Bench judgment, the Ministry of Petroleum and Natural Gas has raised a demand of USD 2.81 billion on the PSC contractors namely Reliance Industries Ltd, BP Exploration (Alpha) Ltd and NIKO (NECO) Ltd," Reliance said in a stock exchange filing.

Originally, Reliance held 60 per cent interest in Krishna Godavari basin deep-sea block KG-DWN-98/3 or KG-D6 while BP had 30 per cent and Canadian firm Niko held the remaining 10 per cent.

Subsequently, Reliance and BP took over Niko's interest in the production sharing contract (PSC) and now hold 66.66 per cent and 33.33 per cent, respectively.

The government had in 2016 sought USD 1.55 billion from Reliance and its partners for the quantum of gas that had migrated to its block KG-D6 from adjoining fields of ONGC.

Reliance contested the claims before an arbitral tribunal which in July 2018 upheld that it was not obliged to pay any compensation.

The government filed an appeal and in May 2023, a single judge of Delhi High Court upheld the arbitration award, dismissing the government's appeal. A division bench of the Delhi High Court last month set aside the single judge order, ruling against Reliance and its partners.

Reliance said the letter of demand was received by the company on March 3, 2025.

"The company is legally advised that the Division Bench judgment and this provisional demand are unsustainable. The company is taking steps to challenge the judgment of the Division Bench of Hon'ble Delhi High Court," it said.

"The company does not expect any liability on this account," it added.

Reliance had previously said that it would appeal the decision in the Supreme Court.

The dispute dates back to July 2013 when Oil and Natural Gas Corporation (ONGC) suspected reservoir connectivity of its KG-DWN-98/2 (KG-D5) and G-4 blocks with that of Reliance's KG-D6.

It felt that at least four wells that Reliance drilled on the borderline with KG-D5 may have drained out its resources as well.

ONGC in May 2013 filed a writ in the Delhi High Court seeking compensation for the loss. On September 10, 2014, the Delhi High Court disposed-off ONGC's petition and directed the government to take a decision, after it received a report from an independent panel set up by ONGC and RIL.

Global consultant DeGolyer and Mac Naughton (D&M) was appointed to carry out a third-party study. In its final report dated November 19, 2015, D&M concluded inter-alia that "the integrated analyses indicated connectivity and continuity of the reservoirs across the blocks operated by ONGC and Reliance." The report quantified the volume of gas migrated from Godavari PML and KG-DWN-98/2 to KG-DWN-98/3 block and respective production of gas from migrated volumes till March 31, 2015.

After submission of the D&M report, the government constituted a single member committee on December 15, 2015, composed of former Chief Justice of Delhi High Court Ajit Prakash Shah "to quantify the unfair enrichment" by Reliance.

The committee concluded that the Government of India, and not ONGC, is entitled to claim restitution from Reliance for the unjust benefit it received and unfairly retained.

ONGC has no locus standi to bring a tortious claim against Reliance for trespass/conversion since it does not have any ownership rights or possessory interest in the natural gas. All mineral resources are the property of the government of India.

Using Shah's report, the government asked ONGC to step aside and took over the matter.

The Ministry of Petroleum and Natural Gas (MoPNG) in a November 4, 2026 order sought disgorgement from Reliance and its partners, demanding USD 1.47 billion from the partners for producing in seven years ending March 31, 2016 about 338.332 million British thermal units of gas that had seeped or migrated from ONGC's blocks into their adjoining KG-D6 in the Bay of Bengal.

After deducting USD 71.71 million royalty paid on the gas produced and adding an interest at the rate of LIBOR plus 2 per cent, totalling USD 149.86 million, a total demand of USD 1.55 billion was made on Reliance, BP and Niko.

The government also pressed Reliance to pay USD 174.9 million of additional profit petroleum after certain costs were disallowed because of KG-D6 output being lower than the target.

Reliance and its partners on November 11, 2016, slapped an arbitration notice.

In July 2018, the international arbitration tribunal rejected the government's claim. The three-member panel by a majority of 2-1 also awarded USD 8.3 million compensation to the three partners.

The government challenged the arbitration award before a single bench of Delhi High Court, seeking it be set aside as it "strikes at the heart of the public policy and has given a premium to a contractor (Reliance) that has amassed vast wealth by committing an insidious fraud as well as criminal offence." Delhi High Court in May 2023 upheld the arbitration award saying "the view taken by the arbitral tribunal is most certainly a "possible view", which calls for no interference." The government approached the division bench of the Delhi High Court against the single bench order. The division bench, comprising justices Rekha Palli and Saurabh Banerjee, on February 15 set aside a May 2023 single bench ruling that had upheld the 2018 arbitration award rejecting the government's claim.
