... and water separately on tubing on the well. The percentage of water cut on oil production tubing is 0% while the percentage of water cut on water production tubing is 100%. This thing shows that DWS completion system will give a greater cumulative oil production in a high production rate and the oil is oil...

... Abstract A successful water injection management is a key to increase or stabilize oil production and to maximize oil recovery from a mature field. This paper describes an approach to draw maximum benefit through existing set up of a water injection in a mature offshore carbonate field of India...

... and it produces oil from Jurassic Brent Group. Oil production from the XYZ reservoir started in early 1978, with 43 producing wells and 15 water injection wells targeting the Rannoch, Etive, Ness and Tarbert sands. Oil and gas production peaked in 1982 and since then production has steadily declined...

... and storage (CCUS) is one such technology which offers dual benefits of carbon sequestration & enhancing oil production from mature oils fields. This paper outlines ONGC's efforts in bringing nation's first CO 2 -EOR project. In view of non-availability of natural CO 2 sources in India, usage...

... in existing wells in the base scenario increased oil production by 11% and net present value (NPV) by 71% with a risk index of 0.38. A numerical optimizer was used to account for possible combinations of 14 potential drilling locations and vertical to horizontal well ratios. A scenario with three vertical...

...'2002, the liquid production was at its highest@ 1560 m 3 /d and corresponding oil rate and water cut were 152 m 3 /d and 89%. After implementation of ASP pilot, water cut declined to 72% by April'2003 and oil production increased to 260 m 3 /d, indicating the efficiency of ASP flooding. Subsequent rise...

... employing horizontal water injectors resulted in better displacement which could be observed from sustained liquid production rates. The reservoir pressure in the area has noticeably improved resulting in reduction in Gas-Oil ratio. In addition, steep decline in oil production per string could be arrested...

... production. However, water cut eventually increased drastically, thereby reducing oil production. To curtail increasing water cut and improve oil recovery, a tertiary recovery method was sought. After closely studying various recovery methods, simultaneous water and gas (SWAG) injection was proposed...

... of about 33.4%. The Scheme is under implementation and has resulted in four fold increase in oil production from around 2600 to 10000 bopd. The present study highlights the importance of integration of all the available data along with finer lithological details, obtained through formation evaluation...

... Abstract The Neelam field is situated in south-east of the giant Mumbai High oilfield in western offshore basin of India. This field was discovered in 1987 and has been put under production since 1990. The field is presently under active water injection and the average oil production from...

... Abstract The HC field was discovered in 1972 and put on commercial production in 1974. The field’s oil production reached life-time high of 461 tpd (tonnes per day) in June, 2006. However, soon the production started declining, rather rapidly, and average production during 2009-2010 was mere...

... wells. Out of total flowing oil wells 91 % are operating on artificial lift with 140 wells on SRP and 159 wells on gas lift. The average rate of production during the year was 1140 tpd of oil and 259000m3/d of gas. The oil production was maintained mainly by development drilling, zone transfers, lift...

... Abstract To enhance production and improve recovery, normal wet In Situ Combustion (ISC) process has been applied by ONGC in the heavy oil field of Balol situated in the state of Gujarat, India.
