ONGC plans Rs 16k cr hi-tech facelift for Bombay High
NEW DELHI: In a rare display of out-of-the-box thinking from a public sector company, flagship explorer ONGC is pumping in nearly Rs 16,000 crore, or $4 billion, into deploying some innovative technological measures to arrest the ageing of Mumbai High oil and gas fields, its crown jewel.
Pumping oil from the field, with complex and irregular rock formations cradling barely 3-8 metre thick oilbearing sub-layers , has remained a challenging task since its discovery in 1974. With production of some 400,000 bpd (barrels per day) at its prime, output has sagged over 32 years to nearly half as age caught up.
Now, in a decisive move to rejuvenate production, ONGC has deployed several smart technologies that keep costs down by reducing the number of platforms or midsea structures for producing the oil trapped in nooks and crannies of the reservoir rock and left behind due to uneven movement of encroaching water in the reservoir. One of the key innovations, a first for India , is the introduction of a rig-mounted platform with 16 slots to drill of up to 16 wells ata depth of 80 metre .

sourceONGC strikes oil and gas in two blocks in the Cauveri basin news
State-run explorer Oil and Natural Gas Corporation Ltd (ONGC) has announced discoveries of oil and gas in two exploratory wells in the Cauvery basin in the east coast.
ONGC notified the two discoveries - North Kovilkallappal-1, an inland exploratory well and GS-KV-1, in the shallow waters offshore KG Basin - both in the Cauvery basin, to the Directorate General of Hydrocarbon (DGH).
ONGC announced the discoveries at its 210th board meeting held on 15 October. The company did not give details of the potential reserves.
ONGC said oil from the exploratory well North Kovilkallappal -1, in L-II PEL block in the Cauvery basin in the Andimadam formation, flowed at 300 barrels a day (40 m3/day) with 6 mm bean at depths of 2,132 to 2,130 metres.
The well, with a total hydrocarbon bearing zone of 2,132 to 2,120 metres, was drilled to a depth of 2,416 metres and has been put on production, ONGC said.
The well also yielded gas at another interval of 2,110-2,112 metres, ONGC said in a release.
