    摘要: Described herein are methods for identifying compounds useful for producing heavy oil from an underground reservoir. The methods facilitate the development of chemicals with improved physicochemical features. The methods generally involve first identifying a physicochemical property of a compound that needs to be improved in order to increase the efficiency of heavy oil removal from underground reservoirs. Next, the physicochemical property is calculated by molecular modeling using semi-empirical or ab-initio calculations. By modifying the molecular model of the compound, the targeted physicochemical property can be optimized. After a suitable compound has been identified, the compound can be synthesized and evaluated.

    摘要: Methods and related systems are described for determining a property of a solid material relating to wettability, and for evaluating chemical additives. A solid particle is positioned at an interface between a lighter fluid phase, such as oil, and a denser fluid phase, such as water. An external force is applied, preferably with a centrifuge, so as to urge the solid particle into the denser fluid phase. An observation is made as to whether the particles has passed through the denser fluid phase, and based on the observation the contact angle is calculated. The calculation is also based on the densities of each fluid phase, of the solid material, the amount of the external force applied, size of the solid material, and interfacial tension between the two phases. The calculation also preferably accounts for two curvatures representing the interface between the first phase and the second phase as deformed by the solid material.

    摘要: A method for generating and characterizing an emulsion. The method provides a Couette device having first and second cylindrical members that define an annulus between them. The second cylindrical member is rotatably driven with respect to the first cylindrical member. Two or more substances each in a non-emulsified state are injected into the annulus. The Couette device is operated in a first mode to generate an emulsion from the two or more substances. The Couette device is also operated in a second mode to measure various attributes of the emulsion.
