.... Initial screening was performed by conducting series of foam stability and foaming ability tests at high temperature. The surface tension and surfactant solution rheology tests were performed to analyze foam behavior. The mixtures of amphoteric and amine-based surfactants were then investigated to improve...

... to their adsorption reduction potential and thermal stability at elevated temperatures. The study estimates this nanoparticle's enhanced oil recovery potential using electrical conductivity, surface tension reduction, and crude oil mobilization. The concentration of SDS was varied from zero-4000 ppm and that of SIC...

... Tension Where Δp is the Laplace pressure difference across a curved surface, r 1 and r 2 are the principal radii of the curvature in each of the axes that are parallel to the surface, σ is the surface tension ( Berry, Neeson, Dagastine, Chan, & Tabor, 2015 ). (1) Δ p = σ • ( 1...

... Abstract Critical flow rate models are widely used for liquid loading prediction in gas wells, take Turner's model as representative, but these models only analyze critical flow rate under wellhead or bottom hole condition, and take surface tension as constant, which results in a relatively...
