ONGC is gearing up to begin a Rs1082.7cr ($163m) campaign to drill 48 explorations wells across 13 mining leases in Gujarat by early 2018.

ONGC, which submitted an EIA report to the Gujarat Pollution Control Board in June, claims one of the planned wells will become the deepest ever drilled in the Cambay basin. "We plan to drill the Dahej well to over 6500 metres," says a source from ONGC's Western Onshore Basin.

He adds this well will be drilled in the Dahej Ext-I ML area in western Bharuch district. All the other 47 wells will be drilled to depths ranging from 400 metres to 4100 metres, each taking 90 to 100 days.

In total the drilling programme will range over a 1456.58-sq km area in south and central Gujarat. Ten wells will be drilled in Gandhar and Gandhar Ext-I to XII; six wells in Dahej, Dahej Ext-I and Dahej South; six in Ankleshwar and Ankleshwar Ext-I; five in Jambusar-Dabka-I, II, III and IV; three in Kosamba and Kosamba Ext-I and II; three in Kim and Kim Ext-I; three in Nada and Nada Ext-I; three in Matar; three in Olpad and Olpad Dandi Ext-I; two in Karvan A and B; two in Kural; one well in Pakhajan and Pakhajan Ext-I and II; and finally one in Umra and Umra Ext-I and II.

ONGC operates all these 13 ML blocks with 100% since 1965.
