Petroleum Minister Murli Deora reviewed the impact of floods in Gujarat on oil installations and supply of products on Thursday.
Directing oil firms to gear up emergency response, he expressed satisfaction that supplies of petroleum products had been maintained with minimum disruption.
While oil refineries in Gujarat worked normally, Oil and Natural Gas Corporation's Hazira gas processing complex has been shutdown for three days.
The closure of ONGC plant has resulted in a revenue loss of about Rs 20 crore (Rs 200 million) per day, besides loss of about 700 tonnes of oil production from ONGC's Mehsana oilfield.
"Floodwater has started receding and the complex is expected to be cleared of floodwater by Friday," it said.
ONGC is mobilising its resources, manpower and expertise to restore the operations of the plant as soon as possible.
Natural gas supplies to industries has been hit, it said but added that supplies to priority sector, particularly CNG for transport sector in Delhi, was being maintained from stocks available and were likely to remain unaffected.
