  • World Oil: Proppant-sized solid inhibitors improve flow assurance in fraced wells

    The economic value of a hydraulically fractured well is highly dependent upon flow assurance—that is, maintaining unimpeded flow of hydrocarbons from the formation to the surface. Flow assurance issues occur in hydraulically fractured wells, as a result of the deposition and buildup of naturally occurring particulates that are present in the system during hydrocarbon production. Scale is ...

  • Viscous Pumping in Focus

    The performance of a pump is influenced when it handles viscous fluids such as crude oil. For the configuration and design of pumps, this is key. In the industry, pump performance curves are developed by testing with water at temperatures around 25°C and corrected to a specific gravity of one. Engineers use this standard so that they have comparable measurement values around the ...
