ONGC and JV partners restart production from PY-3 well in Cauvery basin after 14 years

After 14 years, a joint venture of Oil and Natural Gas Corporation Ltd (ONGC), Hardy Exploration & Production (India) and Invenire Petrodyne has restarted production from the PY-3 Field, located offshore in the Cauvery Basin on the east coast of India.

Originally brought on-stream in 1997, the PY-3 Field had been shut since July 2011. Hardy Exploration & Production (India) Inc., a company of the Invenire Energy Group, is the operator of the block with 22.79% participating interest. ONGC holds a 50.63% participating interest, and Invenire Petrodyne Ltd. holds the remaining 26.58%.

A multi-phase revised Field Development Plan (FDP) has been implemented to revive production. Phase I of the revised FDP has now been completed. This included integrity assessment, conditioning, and activation of the subsea well PD3SA; installation of subsea infrastructure; and hook-up to the Floating Production, Storage, and Offloading (FPSO) vessel Svetah Venetia. The FPSO processes and separates oil, gas, and water. The produced oil is stored on the FPSO and offloaded to shuttle tankers for transport to refineries. Phase II of the FDP will involve the drilling of additional wells and the application of enhanced oil recovery (EOR) techniques to boost output from this prolific field, which yields light, sweet crude oil, said ONGC.

ONGC has discovered seven of India’s eight producing basins and holds the largest exploration acreage and mining license portfolio in the country and accounts for 63% of India’s oil and natural gas production. ONGC also oversees seven non-operated joint ventures, including RJ ON 90/1 and PY-3 fields. Invenire Petrodyne Limited (IPL), formerly Tata Petrodyne Limited, is the flagship company of Invenire Energy Group, with seven upstream oil and gas assets either in production or under development in India and Indonesia.

In a joint statement, Manish Maheshwari, Chairman, Invenire Energy, and Arunangshu Sarkar, Director (Strategy & Corporate Affairs), ONGC, expressed their appreciation to the Ministry of Petroleum and Natural Gas (MoPNG) and the Directorate General of Hydrocarbons (DGH) for their support and guidance.
