Abstract
Surfactants for use in formulations and processes suitable for hydrocarbon recovery. These formulations, include formulations suitable for fracking, enhancing oil and or gas recovery, and the recovery and or production of bio-based oils.
Claims15
A formulation for the recovery of hydrocarbons, comprising:
- at least one surfactant of Formula I:
- wherein R1 and R2 are the same or different, and comprise at least one group selected from the group consisting of C1-C6 alkyl, optionally the C1-C6 alkyl may include one or more of oxygen, nitrogen, or sulfur atoms or groups that include at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
- R3 is selected from the group consisting of alkenyl, alkynyl, ester, alcohol, aryl alkyl, alkoxy alkyl ether, alkyl phosphate, C3-C8 carboxylic acid, C1-C10 alkyl benzoic acid, and a C1-C6 linker attached to a second molecule of Formula I, wherein the second molecule is the same or different;
- n is an integer from 1 to 12;
- and
- X is selected from the group consisting of chloride, bromide, and iodide;
- and
- an aqueous phase.

A method of recovering a hydrocarbon comprising the steps of:
- introducing a foamed fluid composition within an oil or gas well and performing an operation with the foamed fluid composition wherein the foamed composition comprises:
- a base fluid comprises:
- an oil-based or a water-based fluid;
- a gas,
- at least one surfactant of Formula I:
- wherein R1 and R2 are the same or different, and comprise at least one group selected from the group consisting of C1-C6 alkyl, optionally the C1-C6 alkyl may include one or more of oxygen, nitrogen, or sulfur atoms or groups that include at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
- R3 is selected from the group consisting of alkenyl, alkynyl, ester, alcohol, aryl alkyl, alkoxy alkyl ether, alkyl phosphate, C3-C8 carboxylic acid, C1-C10 alkyl benzoic acid, and a C1-C6 linker attached to a second molecule of Formula I, wherein the second molecule is the same or different;
- n is an integer from 1 to 12;
- and
- X is selected from the group consisting of chloride, bromide, and iodide.
