    摘要： A composition comprising a basic solution of oxyalkylated materials wherein at least one of the oxyalkylated materials is an oxyalkylated amine and at least one of the oxyalkylated materials contains an anionic group. Preferably the oxyalkylated materials are derived from hydroxy-compounds such as phenols, alcohols, etc. and amines such as hydroxyamines for example tris(hydroxymethyl)aminomethane and at least one of the oxyalkylates contains a terminal sulfate group preferably derived from reacting the oxyalkylate with sulfamic acid. Preferably the composition contains a CELLOSOLVE such as butyl CELLOSOLVE. A typical composition which is a solution made basic with trisodium phosphate contains1. an oxyalkylated alkyl phenol2. an oxyalkylated tris(hydroxymethyl) aminomethane3. a sulfated, oxyalkylated fatty alcohol, and4. butyl CELLOSOLVE.These compositions are employed as paraffin removers, particularly in petroleum systems.

    摘要： A method and solvent composition for removing viscous crude oil, waxes, asphaltenes and resin precipitates of petroleum origin from oil wells, flow lines and pore spaces of oil-bearing formations. The solvent composition is a mixture of about 45 to about 85 volume percent of a normally liquid aliphatic hydrocarbon boiling in the range of about 120.degree. F. to about 550.degree. F., between about 5 to 45 volume percent of a normally liquid aromatic hydrocarbon, between about 0.5 to about 6 volume percent of an ether of an aliphatic polyhydric alcohol, and between about 1 to about 15 volume percent of a lower alkyl monohydric alcohol.

    摘要： Of the many compositions and methods provided herein, one method includes a method comprising: contacting tar resident in a well bore with a treatment fluid comprising a styrene-acrylate polymer; and allowing the styrene-acrylate polymer to interact with the tar to at least partially reduce the tendency of the tar to adhere to a surface. Another method provided herein includes a method for treating tar sand comprising: contacting the tar sand with a treatment fluid comprising an aqueous fluid and a styrene-acrylate polymer, the tar sand comprising tar and sand; and allowing the styrene-acrylate polymers to interact with the tar to at least partially separate the tar from the sand.

    摘要： A method for cleaning oil wells to increase the flow of oil thereof by use of a unique aqueous cleaning emulsion comprising of water, hydrocarbon solvent, detergent and acid. This one step method provides for the simultaneously cleaning/removal of asphaltene and/or paraffin and scale. This method can be used alone or with the assistance of a wash tool which is a combination pressure and surge wash tool having a nipple assembly. A by-pass port is coupled to the nipple assembly and a diverter cup is coupled to the by-pass port. A plurality of pressure wash cups are positioned on the tool. A pressure wash port is located between the plurality of pressure wash cups and a pump shoe assembly is coupled to a bottom pressure wash cup.
