Cauvery Basin (ONGC only)

ONGC started exploration in the southern peninsular basins of India during the 1950s and made its first discovery in the Cauvery basin with the Madanam gas field in 1970. With the exception of Hardy Oil & Gas (UK), which operates the offshore PY-3 oil field, ONGC is the sole producer in the Cauvery Basin and all its production is located onshore. ONGC's oil production from the Cauvery basin began in 1986 with first gas production four years later. This analysis only includes reserves and costs attributable to fields and licences which fall under concession terms and in which the company has a 100% interest. All of the company's deepwater blocks were awarded during the NELP rounds and fall outside the scope of this analysis.
