ONGC’s Rs 1,892 crore Gujarat drilling push heads for environmental review
Oil and Natural Gas Corporation Limited has proposed a large-scale onshore hydrocarbon development programme involving 349 new wells across Gujarat’s Cambay basin region. The proposed ONGC Gujarat onshore wells project has now been referred to the Expert Appraisal Committee for Fresh Terms of Reference appraisal ahead of environmental clearance evaluation.
The drilling campaign spans eight mining lease blocks across Anand, Kheda and Vadodara districts, with Padra PML accounting for the majority of proposed wells. ONGC plans to drill to an average depth of around 1,200 metres, with each well expected to require 30 to 45 days for completion. The total estimated investment for the development programme stands at Rs 1,892 crore.
The project will connect future production to existing installations including Padra GGS, Kathana GGS, Akholjuni EPS and Anklav EPS. ONGC has indicated that rapid urbanisation in parts of Gujarat’s Cambay Asset is increasing the urgency of exploiting remaining hydrocarbon reserves before land-use pressures intensify further.
The ONGC Gujarat onshore wells project also includes environmental safeguards such as wastewater treatment systems, reuse mechanisms, HDPE-lined pits and water-based mud systems for drilling waste management. Water demand has been estimated at around 22 KLD per well.According to Indian Petroplus analysis, the proposal highlights ONGC’s continued focus on sustaining mature onshore production regions while balancing rising environmental scrutiny around new fossil fuel developments. The project also reflects the growing importance of smaller and medium-depth onshore fields in maintaining domestic oil and gas output stability.
