Problems solved by technology

For example, the formulation described in U.S. Patent Application Publication No. 2014 / 0051620A1, which included an inverting agent such as glycerin, did not react under conditions using water sources with high total dissolved solids, extreme temperatures, or both. Does not provide satisfactory performance

[0065] In an embodiment, the reverse phase agent of the present invention comprises, consists essentially of, or consists of: a hydrosolubilizer. As used herein, a hydrosolubilizer is a water-soluble compound that dissolves a hydrophobic compound in an aqueous solution and includes at least one hydrophilic and at least one minor hydrophobic moiety. As used herein, a minor hydrophobic moiety is a moiety that is insufficient to promote spontaneous self-aggregation, or insufficient to promote accumulation at an interface, or is not long uninterrupted hydrophobic chains, or any combination of the foregoing. As used herein, long uninterrupted hydrophobic chains are hydrocarbyl moieties having 5 or more carbon atoms.

[0066] In an embodiment, the inverting agent of the present invention comprises, consists essentially of, or consists of a compound having an HLB as calculated by the Davies formula:

[0067] HLB=Σ(hydrophilic group share)–Σ(hydrophobic group share)+7

[0068] The H...

In some examples, an inverting agent or an inverting agent in combination with an inverting surfactant facilitates the inversion of the reversible latex under conditions where the water source used to invert the latex comprises about 3.5% total dissolved solids. (Example 3.)

[0074] In an embodiment, the inverting agent or the inverting agent combined with the inverting surfactant facilitates the water source therein for inverting the latex at about 0°C to 100°C and comprising about 0.1 wt% to 30 wt% total Reversible phase inversion of latex under dissolved solids conditions. In some examples, an inverting agent or an inverting agent in combination with an inverting surfactant facilitates reversing the la...

Abstract

Water-in-oil latexes exhibiting water-soluble or dispersible polymers and methods of use thereof. The latex includes a phosphorus functional inverting agent in which the source of water used to invert the latex provides or includes conditions of high levels of total dissolved solids, or both high temperature and high total dissolved solids, at elevated temperatures The following provides rapid and complete inversion of the latex.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 62 / 202,199, filed August 7, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to water-in-oil latexes of water-dispersible polymers and compositions which upon dilution provide rapid inversion of the latex. Background technique [0004] Crude oil development and production can include up to three distinct phases: primary, secondary and tertiary (or enhanced) recovery. During primary recovery, the natural pressure or gravity of the reservoir combined with artificial lift techniques (such as pumps) that bring the oil to the surface drive the oil into the wellbore. But typically only about 10% of the in situ virgin oil of an oil reservoir is produced during primary recovery. Secondary recovery techniques typically extend the production period of an oil field by inj...
