ONGC makes oil discovery in offshore Mumbai, India


India's state-owned company Oil and Natural Gas (ONGC) has made a significant discovery west of the Mumbai High oilfield in the Arabian Sea. 

Discovered at drilling well WO-24-3, the find is estimated to contain in-place reserves of around 20 million tonnes of oil equivalent, reported Reuters. 

As part of the drilling campaign, ONGC tested nine zones in the well and all of them encountered hydrocarbons. 

One of the zones yielded more than 3,000bpd of oil. 

Currently, ONGC continues to drill appraisal wells at the site to confirm the discovery's size. The company has also informed the Directorate General of Hydrocarbons (DGH) about the recent discovery. 

"One of the zones yielded more than 3,000bpd of oil." 

Mumbai High oilfield is located 176km off the coast of Mumbai, India, in water depths of 75m. 

A Russian and Indian oil exploration team discovered the field while operating from the Academic Arkhangelsky seismic exploration vessel at the time of mapping of the Gulf of Khambhat during 1964-67. 

The new discovery is expected to enable ONGC to continue production for a longer period at Mumbai High than earlier estimated.  

In addition, the company intends to use the facilities and infrastructure at the nearby WO-16 field to develop the new discovery.
