Surfactant screening to generate strong foam with formation water and crude oil

Abstract Most of the available commercial surfactants precipitate due to hardness formation water. The study surfactant generated foam and its stability is very complex multifaceted pattern common physicochemical properties. This research involved generation by using blended their evaluation in terms enhanced oil recovery (EOR). objective this systematic screening based on capability produce stable presence two different categories crude oil. Surfactant types such as non-ionic, anionic amphoteric were selected for experimental study. was with oil, synthetic brine water 34,107 ppm used concentration both decay, liquid drainage longevity investigated measuring volume above level. 0.6wt%AOS C14-16 , 1.2wt%AOS + 0.6wt%TX100 0.6wt%LMDO resulted maximum 50% decay solutions noted time. findings demonstrated that dependent type either individual or concentration. blend solution combines excellent
