Oil and Natural Gas Corporation (ONGC) has drawn up plans to invest over Rs.4,051 crore in revamping infrastructure at its key oil and gas fields off the Mumbai coast.

In a statement, ONGC said it planned to invest Rs.2,913.10 crore for revamping 48 aging platforms at Mumbai High and Neelam & Heera oil and gas fields. After the recent redevelopment efforts, these fields are expected to be in production till at least 2030 but the existing infrastructural facilities will not last that long. “Hence, revamping/retrofitting of these facilities in a phased manner is essential to maintain the production of oil and gas from Mumbai High and Heera fields,’’ the statement added.

The ONGC board, which met on Wednesday, gave the green signal to the revamp of 48 platforms on these fields by mid-2016. Also, it approved a Rs.1,138.50-crore revamp of BPA and BPB process complexes on the giant Bassein & Satellite gas fields in the Western offshore. “Both the complexes have already covered the normal design life of 25 years.

“As per prevailing Refurbishment Policy based on recommendations of statutory bodies, it is proposed to carry out revamping for various static equipment and pipelines of these two complexes,” it added.

While the revamping job of BPB is planned to be completed in 2013-14, the same for BPA is scheduled for completion in 2014-15.

Further, ONGC said it had made an oil discovery in a KG basin block in Andhra Pradesh. Exploratory well Vanaduru South-1 in West Godavari block of KG onland Basin, 8 km north-west of Bantumillli town of West Godavari district in Andhra Pradesh, found very high quality oil. In shallow waters of KG basin, its exploratory well Saveri-1 in NELP block KG-OSN-2004 flowed gas and condensate.

“This high potential discovery augments the hydrocarbon volumes established through two earlier discoveries, namely, Chandrika South and Alankari in the block, and is a significant boost to ONGC’s efforts towards attaining critical hydrocarbon volumes for viability of a possible cluster-based development for the block,” the statement said.

In Tripura, gas was discovered in an exploratory well AD-37, 12 km south-west of Agartala.
