These surface-active solvents and surfactants can be used advantageously in several Chemical EOR applications. The surface active solvents have been shown to improve polymer flooding, viscous oil recovery, unconventional oil recovery, ACP(alkaline-cosolvent-polymer) applications, etc. Several of these processes have the potential of going to field trials. The raw materials used to make these surface active materials are abundantly available and should be a definite plus for commercial productions.

Dr. Upali Peter Weerasooriya started his professional career with a B.Sc (Honors) degree in Chemistry Special from the University of Sri Lanka in 1971. After 4 years of Industry experience, he proceeded to USA to do an M.S degree in Chemistry at Bowling Green State University in Ohio (1975 – 1977), followed by a Ph.D degree at The University of Texas at Austin. After graduation in 1980, he worked in the Chemical EOR program in the Chemistry department until 1983 before joining British Petroleum in Cleveland, OH. Next, he joined Conoco Chemicals in Ponca City, OK and stayed there until early retirement in 2000. He then joined Harcros Chemicals in Kansas City, KS until retirement as V.P and CTO in 2008.
