摘要： Alcohol compatible, water-soluble copolymer useful as a corrosion inhibitor. The copolymer includes at least one olefinically unsaturated carboxylic acid monomer, at least one olefinically unsaturated mono- or di-alkyl ester of a di-carboxylic acid monomer, and at least one olefinically unsaturated hydrophilic, non-ionic monomer. The molar ratio of the alkyl ester groups of the mono- or di-alkyl ester of the dicarboxylic acid monomer to the hydrophilic groups of the hydrophilic, non-ionic monomers is from about 0.01:1 to 1000:1, and the molar ratio of the sum of the alkyl ester groups and hydrophilic groups of the hydrophilic, non-ionic monomers to the carboxylic acid groups, is from about 0.001:1 to 100:1. No haze or precipitate occurs in a mixture of the water-soluble copolymer at 4° C. for 15 hrs or more as a 20 weight % aqueous copolymer solution in alcohol at a water-soluble copolymer to methanol weight-ratio of not more than 25 to 100.

摘要： The present invention generally relates to controlling the viscosity of water-based mud systems. More particularly, the present invention relates to methods and compositions for thinning and deflocculating aqueous based fluids used in well drilling and other well operations in subterranean formations, especially subterranean formations containing oil and/or gas. The invention also relates to a drilling fluid thinner and/or dispersant having improved temperature stability, dispersing properties and “solids contamination” tolerance.

摘要： Barium sulfate and/or calcium carbonate scale inhibitor composition composed of a water-soluble polymer having incorporated phosphate functionality, the polymer being formed from at least one ethylenically unsaturated carboxylic acid monomer, at least one ethylenically unsaturated vinyl sulfonate monomer, or a mixture thereof. The scale inhibitor composition can be used as a means of detecting inhibitor composition in downhole and topside oilfield treatments by means that are faster and more accurate than turbidometric measurement.
