Abstract: Described herein are systems and methods for evaluating and mitigating the wax risks of a given hydrocarbon composition such as crude oil. The disclosed systems and methods enable rapid and ready prediction of wax risks using algorithms based on a small sample of the hydrocarbon composition. The wax risks are predicted using predictive models developed from machine learning. The disclosed systems and methods include mitigation strategies for wax risks that can include chemical additives, operation changes, and/or hydrocarbon blend.

Abstract: Water, for example produced water from a steam assisted gravity drainage (SAGD) or cyclic steam stimulation (CSS) heavy oil recovery operation, is treated, for example to recover water re-use in creating steam. The produced water is concentrated, for example in one or more thermal treatment devices such as an evaporator and a crystallizer. A solvent and a compound or solution comprising multivalent cations is added to the concentrate. Solids precipitate and are separated from the concentrate. The solvent may be recovered for re-use in treating more concentrate.

Abstract: Produced water, for example from a steam assisted gravity drainage (SAGD) or cyclic steam stimulation (CSS) heavy oil recovery operation, is treated to recover water that is re-used to create steam. The produced water is treated in one or more thermal treatment devices such as an evaporator and a crystallizer. The thermal treatment produces a slurry comprising dispersed or dissolved salts and organic compounds. A water-miscible solvent for one or more of the organic compounds, for example methanol, is added to the slurry. The solids precipitate and are separated from the slurry. The solvent may be recovered for re-use in treating more slurry.
