    摘要: Composites containing a hydrocarbon-soluble well treatment agent may be supplied to a well using a porous particulate. Such well treatment agents may for example inhibit the formation of paraffins, salts, gas hydrates, asphaltenes and/or other deleterious processes such as emulsification (both water-in-oil and oil-in-water). Further, other well treatment agents include foaming agents, oxygen scavengers, biocides and surfactants as well as other agents wherein slow release into the production well is desired.

    摘要: Homopolymers and copolymers of an esterified reaction product of an epoxidized mono-hydroxyl alcohol and a free radical polymerizable monomer are highly effective demulsifying agents. The molecular weight of the polymer is between from about 10,000 to about 500,000. The epoxidized mono-hydroxyl alcohol is preferably a reaction product of a C6–C30 linear or branched alcohol and an alkylene oxide. The alkylene oxide is preferably either ethylene oxide, propylene oxide or butylenes oxide or a mixture thereof. The free radical polymerizable monomer is preferably a vinyl aromatic compound or an acrylic or methacrylic based monomer. The polymer preferably comprises a micellar assembly. Such polymers are highly effective in demulsifying crude oils having API gravities of from 8 to 28 or a crude oil having a viscosity between from about 3 to about 10,000 CPS @ at 25° C.
