Abstract:
This invention relates generally to novel foamer compositions for treatment of oil and gas wells to enhance production. The invention provides a method of foaming a fluid. The method includes introducing into the fluid a foam-forming amount of a composition comprising at least one long chain fatty acid and at least one organic solvent. An example of the long chain fatty acid is tall oil fatty acid and an example of the organic solvent is ethyleneglycol monobutyl ether
Abstract:
A method of removing metals and amines from crude oil comprising adding an effective metal removing amount of one or more hydroxycarboxylic acids selected from lactic acid and malic acid and salts thereof to said crude oil; adding wash water to said crude oil; mixing said crude oil, acid and wash water to form an emulsion; and resolving said emulsion into an aqueous phase and crude oil having a reduced metals content.
Abstract:
Provided herein are compositions useful as detergents in cleaning a wide variety of substrates, including hard surfaces and laundry. The compositions contain a water-soluble polymer, which is a co-polymer between a polymerizable amide and a second, ethylenically-unsaturated monomer. The polymerizable amide itself is prepared from an amine-capped, alkoxylated alcohol by reaction with maleic acid anhydride. Compositions according to the invention show enhanced cleaning performance and beneficial anti-redeposition properties.
Abstract:
Provided herein are compositions useful as ink which contain novel dispersants that are capable of dispersing pigments which are traditionally difficult to disperse while maintaining acceptable levels of viscosity. Use of dispersants as taught herein enables the preparation of a wide variety of inks having high pigment loading and existing within a conventionally useful viscosity range.

Abstract:
A method of foaming a fluid for recovering gas from a gas well and enhancing oil production from a gas-lifted oil well penetrating a subterranean oil-bearing formation is disclosed and claimed. The method includes introducing into the fluid a.foam-forming amount of a composition comprising at least one compound having the general formula (A); R1 is selected from a saturated linear or branched alkyl, an unsaturated linear or branched alkyl, a substituted naphthalene, a substituted benzene, a natural oil, and a natural oil derivative. R2 is a C2-C8 alkyl R3, R4, and R5 are independently selected from trimelhyl. triethyk diethyl,, monoethyl, benzyl dimethyl, and benzyl diethyl. X is selected from hydrogen, methyl, and ethyl. Z- Is a negatively charged counterion.
