New Delhi: Reliance Industries has said its flagship natural gas fields in the KG-D6 block in the Bay of Bengal are in “a late life stage” with output plummeting to an all-time low. The company, beginning mid-2020, will bring to production three sets of new discoveries in the block that will reverse the years of decline in production. Dhirubhai-1 and 3 — once the country’s highest gas producing fields — are “in a late stage and affected by low pressure and water ingress related challenges,” the company said in an investor presentation post announcing June quarter earnings. The fields produced an average of 1.76 million standard cubic metres per day of gas during April-June, the firm said.
