New Delhi: Oil and Natural Gas Corp (ONGC), India’s largest oil and gas producer, has found an underground fresh water reservoir near Jaisalmer in Rajasthan. ONGC drilled Saraswati-1, the first of its seven wells to find water in deserts of Rajasthan, to a depth of 554 m, deeper than any known water well in the area.
“Presence of relatively fresh water in a zone from 450 to 530 m was indicated,” a company official said. The water found at such depths is usable for all purposes, and can easily be made potable by using suitable techniques. Blending the tubewell water with canal water supplies could augment the available potable water supply to Jaisalmer town.
In October 2005, ONGC board accorded approval for an initial expenditure of Rs1.7 crore for the pilot study covering 13 districts of western Rajasthan. Drilling locations were identified in Bikaner, Barmer and Jaisalmer districts.
The official said the company is continuing with the project, and has extended the scope to cover Haryana also. Further surveys and drilling will be carried out after firming up suitable locations for locating deep underground fresh water resources. “ONGC is committed to its corporate social responsibility, making a contribution beyond its commercial interests to the people in making their tomorrows brighter,” he said.
