Conformance Control in Oil Reservoirs by Citric Acid ...
Conformance Control in Oil Reservoirs by Citric Acid ...

Reservoir conformance control methods may significantly improve enhanced oil recovery technologies through reduced water production and profile correction. Excessive water production in oil and gas reservoirs leads to severe problems. Water shutoff and conformance control are, therefore, financially and environmentally advantageous for the petroleum industry. In this paper, water shutoff ...

This also causes a lower CO 2 stripping, which could result in a reduced pH level for ,wastewater, with low buffer/,acid, capacity and inhibited nitrification processes at pH levels under 6.6. To solve this problem, it could be required to add chemicals (e.g., milk of lime; cf. [ 47 ]) or add additional aeration times for the system (cf. [ 46 ]) to sustain the biological treatment.

Biochemical oxygen demand - Wikipedia

Biochemical oxygen demand, (BOD) is the amount of dissolved oxygen (DO) needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a ...
