New Delhi: Union Minister of Petroleum & Natural Gas Hardeep Singh Puri dedicated two major projects of ONGC to the nation at Western offshore on Saturday. He was accompanied by ONGC's CMD Dr Alka Mittal, Director (T&FS) OP Singh and Director (Offshore) Pankaj Kumar. The two projects will result in an incremental gain of 7.5 MMT of oil and more than 1 BCM of gas.
The minister expressed his appreciation for the ONGC team for implementing the two projects. He exhorted ONGC to further enhance their efforts to add more oil and gas to the kitty of the nation by adopting accelerated exploration activities.
The state-of-the-art eight legged water Injection-cum-Living Quarter platform has been installed as part of the implementation of the low salinity waterflood (LSWF) process, an Enhanced Oil Recovery (EOR) pilot project, part of the Mumbai High South Redevelopment phase IV at a total CAPEX of Rs 3,740 crore. NWIS-R was installed under the government initiatives of enhanced recovery (ER) policy 2018 for oil and gas. The project will result in an incremental gain of 3.20 MMT of oil and 0.571 BCM of gas. This is the first EOR project for Indian offshore.
The concept involves reducing the salinity of the injected seawater, which is about 28,000 ppm, up to the level of 8,250 ppm with a desalination plant. The mechanism of LSWF involves complex Crude Oil-Brine-Rock (COBR) interactions for improving both microscopic and macroscopic displacement efficiency.
The project has been implemented with a strategic emphasis on local procurement of Rs 1,700 crore, in line with the Make in India Initiative of the government. Out of total 45 major Pumps/packages in NWIS project, 42 major Pumps Packages have been manufactured in India. 40,000 MT of Structural Steel, enough of make 5 Eiffel Towers have been used in the structure.
The Energy Recovery Unit to save power will result in reducing 8,314 MT of C02 emission yearly thereby reducing carbon footprint.
The cluster 8 Marginal Field development project at Mumbai High has been implemented at a total cost of Rs 2,292.46 crore. The project will result in incremental production of 4.38 MMT of oil and 0.464 BCM of gas, said ONGC. These marginal fields were discovered in 2017-18 and 2018-19. CO2 mitigation system has been implemented for the first time offshore as part of the project. The oil and gas are being evacuated through FPSO (Floating Production Storage and Offtake).
