Chemical Experiments with Fresh, Hot, Partly-Flashed Hypersaline Brine

Abstract

Chemical behavior of single phase liquid obtained at a wellhead has been quantified by novel test procedures that yield novel results. Chemical reagents were injected into the brine stream and the mixture passed through a series of chambers that stabilize at different temperatures between 400 and 200°F. Results show the brine's overall behavior is due to multiple reactions that respond unequally to added chemicals. Significant changes in the texture of deposited solids are elicited by plain water as well as by other chemicals. Methods to control or moderate scale deposition and formation of sludges can take advantage of thee behaviors.
