Oil and Natural Gas Corporation (ONGC) entered into an MoU with Exploration Company BV (a subsidiary of Royal Dutch/Shell) earlier this yearr to enable future collaboration along the energy value chain in upstream and downstream sectors. ONGC is re-negotiating this broad-spectrum collaboration understanding with Royal Dutch Shell. Shell's proposed participation in setting up high-grade bitumen manufacturing capacity, petrochemicals and coal gasification projects will depend on the outcome of the negotiations.
