    摘要： A method to invert a water-in-oil emulsion to an oil-in-water emulsion comprises contacting the water-in-oil emulsion with an aqueous colloidal dispersion including hydroxides of elements of Group II and Group III of The Periodic Table of Elements and mixtures thereof and then mixing the water-in-oil emulsion and aqueous colloidal dispersion until the water-in-oil emulsion inverts to an oil-in-water emulsion.

    摘要： Methods are provided for separating algae from an aqueous environment. An aqueous feed containing algae can be mixed in a turbulent manner in an aerated environment. The turbulent mixing can be sufficient to create a foam within the aqueous feed. The formation of the foam can also result in agglomeration of algae into larger size algae aggregates, which can then be filtered under pressure. Due to the larger size of the algae aggregates, the pressurized filtration can reduce/minimize the tendency to clog the filter, as the algae aggregates can generally be too large to fit within the pores of the filter. The filter can preferably be located at the bottom of the vessel holding the aqueous feed. This can assist in allowing the algae to remain in a cake above the filter, as opposed to having the algae dissolve back into the aqueous feed.

    摘要： Fluids for use in hydrocarbon recovery operations include water and at least one organo-anionic surfactant. The fluids may be used in methods for conducting hydrocarbon recovery operations, such as drilling operations, completion operations, production operations, injection operations. The fluid may be adapted to remediate a NAF filter cake. Exemplary organo-anionic surfactants may include one or more of monoethanol ammonium alkyl aromatic sulfonic acid, monoethanol ammonium alkyl carboxylic acid, and mixtures thereof.

    摘要： A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of one or more oil dispersible or oil soluble polynuclear aromatic compounds, or functionalized lignin, is added or contacted with the resid or heavy oil at a point before or after the step of heating the heavy oil to coking temperatures. The addition of additives facilitates the formation of shot coke and inhibits the formation of sponge coke.
