Discussing the field’s journey, Prachur Sah, Deputy CEO, Cairn Oil & Gas said, “Considered to be in the last league of its production cycle in the early-2000s, Ravva’s life has exceeded expectations as Cairn continues to deploy the latest technologies. As the asset enters its 28th year of production, its recovery rate has set an industrial benchmark. Ravva further proves that technology and digitalization can help the country gain more from its existing resource capacities. The Ravva field is a national asset that also boasts of world-class safety standards.”
The Ravva field has achieved recognition for its technological standards. It is home to India’s first TCP under balance-perforating with multilane completion technique, which has granted access to multiple reservoirs from the same bore, improving recovery and asset reservoir management. Deploying expandable sand screens that control sand production in the wells has further swelled production capacities and increased savings.
This has borne rich results – from a mere 3,500 barrels per day, the field touched a peak of 50,000 barrels per day and maintained it for over a decade. The field today remains relevant as it continues to produce ~15,000 barrels per day and even touched a peak of 25,000 barrels per day in the last year. It has also proven to be one of the most economical fields globally.
Furthering the vision of parent company Vedanta Ltd., Cairn’s Ravva asset is also home to a slew of ESG initiatives. The company has developed a five-phase green belt of salt-tolerant species in Ravva, beginning in 1996. The site is also a hotspot for mangrove plantations and provides an excellent roosting site to several avifaunal species.
The field also subscribes to the highest benchmarks of safety in operations and quality of services. It has duly been certified as ‘Conforming to 5S’ by Intertek. The Ravva block also recently received the Gold Award from the Quality Circle Forum of India.
India’s first offshore asset which has consistently contributed to the country’s energy basket, Ravva remains a benchmark for ageing fields that can bring gains with consistent investment and technology deployment.
