The document discusses a gas dispute between Reliance Industries (RIL) and Reliance Natural Resources Limited (RNRL) over the supply of natural gas from RIL's KG Basin block. RNRL argues it has a right to receive gas from RIL's KG Basin block based on a 2005 family agreement to split assets between two brothers. However, RIL disagrees and a legal battle has ensued over whether RIL must supply gas to RNRL and at what price. The outcome of the court case could significantly impact the revenues and costs of RIL, RNRL, other companies, and influence gas prices in India.
