Abstract
The object of the present invention is a composition comprising amine compound and carboxylic acid compounds, wherein at least the amine compounds are alkoxylated, use thereof as a drilling fluid, and a method for using the drilling fluid
Claims45
A composition comprising:
- (A) at least one of primary, secondary, tertiary alkoxylated amine compounds, or mixture thereof and
- (B) at least one of carboxylic acid compounds selected from at least one of polyalkene glycol ether carboxylic acids of a monoalcohol, poly-alkylene glycol ether carboxylic acids of a polyol, or mixtures thereof
- (C) an oil that is liquid at least at 25° C., and
- (F) water,
- wherein the composition further comprises salts dissolved in the water (F) in a concentration of greater than 1% by wt. an the composition is a water-in-oil-emulsion wherein the oil (C) forms the continuous phase and the water (F) forms the dispersed phase.

A method of improving flow of heavy hydrocarbons comprising
- introducing a composition comprising:
- (A) one or more primary, secondary or tertiary alkoxylated amine compounds and
- (B) one or more carboxylic acid compounds selected from one or more members of the group of polyalkylene glycol ether carboxylic acids of a monoalcohol and poly-alkylene glycol ether carboxylic acids of a polyol,
- (F) water,
- wherein the composition further comprises salts dissolved in the water (F) in a concentration of greater than 1% by wt. and the composition is a water-in-oil-emulsion wherein the oil (C) forms the continuous phase and the water (F) forms the dispersed phase,
- into heavy crude oils or extra heavy crude oils to form water-in-oil emulsions with reduced viscosity.
