Effects of pH and Temperature on Oilfield Scale Formation

Water flooding is one of the most influential methods for pressure maintenance and enhanced oil recovery. However, water flooding is likely to develop the formation of oilfield scale. Scale formation in reservoirs, due to the mixing of injection water and formation water, could cause formation damage and production limit. Therefore, it is necessary to simulate the compatibility of brine and inj...

Risk assessment and mitigation measures on the heavy metal polluted water and sediment of the Kolleru Lake in Andhra Pradesh, India

The Kolleru Lake is a famous Ramsar wetland of international significance. In this study heavy metal contents in water and sediment samples are reported. It is found that certain potentially toxic metal ions like chromium (4.5-80 µg/L), copper (1-20 µg/L), manganese (1-313 µg/L) and zinc (1.2-57 µg/L) are present in variable quantities in the lake water. When normalized with respect to concentr...
