... surfactant coalescence time petroleum engineering Oil-water emulsions account for a significant portion of the world’s crude oil production. Oil-water emulsions have wide range of usage area in the petroleum industry, particularly in hydraulic fracturing, drilling well operations, and acidizing...

... despite their numerous applications. In this work, diesel/water emulsions were prepared using octylphenol ethoxylate as an emulsifier at different mixing times and speeds, varying surfactant concentrations, and using different water/diesel ratios. The emulsion stability was evaluated using a bottle test...

... such as water content varied from 9%, 12%, and 15%, surfactant dosages of 5%, 10%, and 15% and the hydrophilic–lipophilic balance (HLB) values of 6, 7, 8, and 9 were varied to study its impact on microexplosion phenomenon. Three different sizes of emulsion droplets of approximately Ø2.8 mm, Ø2.2 mm, and Ø0.3 mm...

...Jeffrey D. Childs; Edgar Acosta; John F. Scamehorn; David A. Sabatini Surfactant-enhanced washing of oil-based drill cuttings was evaluated as a technology of benefit to domestic oil producers. Laboratory studies showed the branched C14-C15 alcohol propoxylate sulfate to be a promising surfactant...
