In this research work, systematic experimental studies of chemical flooding were conducted for heavy crude reservoir. Alkali-Surfactant-Polymer (ASP) flooding in the reservoir may enhance the crude oil recovery; it may lead to adsorption of flooded chemicals. These flooded chemicals are very expensive and high rate of adsorption will make the recovery uneconomical. Analysis of petroleum core flood effluent has to be done, to study dynamic adsorption. This experimental work shows the selectivity of ASP flooding for heavy oil and increase in percentage recovery of heavy oil with optimizing ASP concentrations. The results also show that polymer flooding is quite effective at low oil saturation.

Corrosion occurred by this produced water from oil industry is very difficult to be predicted. Produced water reinjection, treatment and disposal are a huge problem in onshore as well as offshore fields. As the reservoir depletes, mostly the water cut increases up to 90%, thus increasing the chances of corrosion of the surface and subsurface equipment. In this experimental work corrosion studies were undertaken on steel tubular at reservoir temperature. It is essential to remove the dissolved oxygen to control corrosion. The dissolved oxygen content in effluent was found to be high. The dose of sodium sulphite as oxygen scavenger after treatment of the injection water in the laboratory is optimized. Dissolved oxygen may vary from time to time; therefore the dose of oxygen scavenger may be changed accordingly for effective removal of oxygen. Sodium sulphide requires a catalyst like Cobaltous chlo...

To increase oil production from existing wells in an oil field we have to focus much on optimizing oil production. One way to optimize oil production is to find an alternative to existing intermittent gas lift technology. As we study big oil field currently with huge oil and gas operating companies, the gas injection line network is very old and new intermittent gas lift installations on new wells has been connected to the existing network. Now this creates gas starving for the new installations and resulting in inadequate amount of gas production from the well. By introducing Plunger lift technology of artificial gas lift along with existing intermittent gas lift can provide a fool proof solution to the problem and also reduction in injected gas requirement also. Thus, reducing the compressor duty and overall reduction in environmental emission of harmful gases by reducing the diesel engine load required previously for compression. This paper discusses in detail with proof in form of tables, increase in oil production and reduction in injection gas requirement and reduction in emission of harmful gases to the environment.
