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, and detergent. 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.

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： Fluid producing wells may be treated with a water-in-oil emulsion for the removal or inhibition of unwanted solid particulates, including pipe dope, asphaltenes and paraffins. Such emulsions are of particular applicability in the displacement of oil base drilling muds and/or residues from such muds from producing wells. The water-in-oil emulsions may optionally contain a dispersing agent as well as a surfactant.

摘要： The invention involves the demulsification and liquefaction of hydrocarbon based sludges. A demulsifier and a liquefaction agent and methods of using the same are disclosed. In a preferred embodiment, the demulsifier contains a salt of DDBSA, polypropylene glycol, and citrene. In a preferred embodiment, the liquefaction agent contains a glycol ether and sodium silicate. In another preferred embodiment, the liquefaction agent contains a glycol ether and citrene. In preferred practice, the sludge is treated with the liquefaction agent, circulated, treated with the demulsifier, and circulated further. An object of the invention is to provide a hydrocarbon based sludge that is sufficiently liquefied to be pumped and which is sufficiently demulsified to allow the waters, oils, and solids in the sludge to separate.
