Production and Uses of C14-C20+ Alkyl Benzenes and C14-C20+ Alkyl Benzenes Derivatives in Enhanced Oil Recovery

A previous research disclosure (IP.com Number: IPCOM000205556D) describes the production and uses of C14-C20+ alkyl benzenes and their derivatives in a variety of applications. This document provides an overview of the uses of such chemicals in the field of enhanced oil recovery.

Enhanced Oil Recovery (often abbreviated EOR) is a generic term for techniques for increasing the amount of crude oil that can be extracted from an oil field1. One general category of EOR methods involves the use of surfactants to mobilize trapped oil through emulsification, wettability alteration, or other mechanisms2.

Alkyl aromatic sulfonates, and especially alkylbenzene sulfonates, comprise one class of many surfactants suitable for EOR application. Early references disclose the use of alkylbenzene sulfonates of several molecular weights simultaneously3, the use of one or more alkylbenzene sulfonates of which one is an oil-soluble sulfonate of molecular weight 400 or higher4, and the details of surface chemical properties of a variety of alkyl benzene sulfonates relevant to EOR processes5.

Later work, exemplified by patents in the table below, teaches the further use of alkylbenzene sulfonates and other alkyl aromatic sulfonates in a range of formulations with other surfactants and chemicals, further de...
