    摘要： An operations fluid is provided for treatment operations on wellbores associated with hydrocarbon production, the operations fluid comprising: water, an inorganic primary acid; and an alkyl acid surfactant. The alkyl acid surfactant has the general formula {R—X}, wherein R comprises at least one of linear and branched alkyl and alkyl aryl hydrocarbon chains and X comprises an acid, and X may comprise an acid selected from the group comprising sulfonic acids, carboxylic acids, phosphoric acids, and mixtures thereof. The alkyl acid may include an acid selected from the group consisting of alkyl or alkyl aryl acids. The operations fluid may be useful in treatment operations related to formation stimulation or mitigation of non-aqueous filter cakes (NAF) and/or formation invasion by NAF drilling fluids.

    摘要： A method of demulsifying a water-in-oil emulsion is provided. The method includes treating a volume of fluids comprising oil and water by adding a salt of a polynuclear, aromatic sulfonic acid to the fluids so as to cause the oil and water to be at least partially demulsified. The method may further include separating water and oil in a separator. A method of producing hydrocarbons from a subsurface reservoir is also provided. The hydrocarbons include a water-in-oil emulsion. The method includes producing the hydrocarbons through a wellbore, and subjecting the water-in-oil emulsion to a salt of a polynuclear, aromatic sulfonic acid additive so as to cause the oil and water to be at least partially demulsified.

    摘要： A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of oil dispersible or oil soluble metal salts of aromatic sulfonic acids and/or polysulfonic acids 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.
