The Oil and Natural Gas Corporation (ONGC) has begun gas production from its block in the Krishna Godavari basin in the Bay of Bengal and is planning a ramp up production in coming weeks.
ONGC's KG-DWN-98/2 or KG-D5 block sits next to Reliance Industries' flagging KG-D6 area.
The company began production from the first well on the KG-D5 block and is currently producing around 0.25 mscmpd. It is doing a build-up mapping and the production is likely to rise to 0.75 mmscmd within next few weeks
ONGC is investing USD 5.07 billion in developing the oil and gas discoveries in the block.
The project will cumulatively produce around 25 million tonne of oil and 45 billion cu mtr of gas with peak production of 78,000 barrels per day of oil and 15 mscmpd
After successfully commissioning its first deep water project S1 Vasishta in eastern offshore in March 2018 (which will be yielding about 4.3 mmscmd of gas), ONGC is now concentrating on the flagship project from the New Exploration Licensing Policy (NELP) block KG-DWN-98/2 in the deep water of eastern offshore
Thirty four wells are to be drilled under the project. Of these 34 wells, 15 are oil-producing, eight are gas producing and 11 are water-injecting wells
The discoveries in the block are divided into three clusters -- Cluster-1, 2 and 3. Cluster 2 is being put to production first
Cluster 2 field is divided into two blocks, namely 2A and 2B, which are expected to produce 23.52 million tonne of oil and 50.70 billion cu mtr (bcm) of gas. Oil production is likely to start shortly
Associated natural gas from Cluster 2A of the project will have a peak production of three mmscmd of gas and 78,000 bopd of oil with a 15-year profile; non-associated natural gas from Cluster 2B will have a peak free gas production of 12.25 mmscmd with a 16-year profile
The KG-DWN-98/2 involves some of the most advanced oil field technologies in drilling and completion of 34 sub-sea wells, laying about 425 km of pipeline and 150 km of control umbilical in water depths varying from 300 to 1,400 mtr
An Offshore Process Platform for processing and evacuating 6.5 mmscmd of gas has been built. Balance 5.75 mmscmd gas will be transported through ONGC's existing sub-sea infrastructure and facilities, created at onshore terminal of Odalarevu at the Andhra coast. Floating Production, Storage and Offloading Vessel (FPSO) will also be deployed in water depth of 413 mtr to process the oil and gas
The Cluster 2A is estimated to contain reserves of 94.26 million tonne of crude oil and 21.75 bcm of associated gas, while Cluster 2B is estimated to host 51.98 bcm of gas reserves
Cluster 2A is anticipated to produce 77,305 barrels of oil per day (bopd) and associated gas at a rate of 3.81 mmscmd
Cluster-2B is expected to produce free gas of 12.75 mmscmd from eight wells and has a 16 year life
