Question : CRUDE OIL FROM MUMBAI HIGH OILFIELDS

(a)The total quantity of crude oil produced from the Mumbai High Oilfields in Maharashtra during the last three years;
(b)Whether the production of the crude oil is less than the target fixed;
(c)If so, the details thereof; and
(d)The steps taken by the Government to explore maximum crude oil from the Mumbai High Oilfields?

Answer given by the minister

MINISTER OF STATE IN THE MINISTRY OF PETROLEUM AND NATURAL GAS
(SHRI SANTOSH KUMAR GANGWAR)

(a) to (c): The production of crude oil from Bombay High v/s the targets during last three years was as under:-

(Figs. in MMT)
Year Target Achievement
1996-97 13.928 12.040 1997-98 10.769 12.434 1998-99 12.050 11.586
The main reason for shortfall in production is that the main producing reservoirs of this oilfield have entered the natural declining phase. Some of the wells are flowing with high gas oil ratio and increasing water cut.

(d): In order to improve the performance of the field and increase the recovery factor, a monitorable action plan has been prepared by the expert committee which includes:- Reservoir characterisation for better understanding of the complexities of the multi-layered reservoir of Bombay High field through the recently acquired 3-D seismic data. Drilling of in-fill wells to exploit by passed/undrained parts of the giant field. Re-distribution of injection water for improved conformance. Re-completion of poor performing wells. Engaging of reservoir consultant of International repute by ONGC for planning the future development strategy to improve the recovery from the field. Engaging of services of the experts by ONGC on application of Gel technology on trial basis in some identified wells for controlling excessive gas and water production and conformance control in injectors.
