Applications

Enhanced Oil Recovery

Esteem Industries has spent several years focusing on specialty surfactants for EOR applications. The typical EOR surfactant is capable of reducing interfacial tension at the surface of an oil droplet to ultra-low levels (< 10-4 dynes/cm). This unique technology is the subject of several global patents. The efficacy of these built-for-purpose surfactants stems from the presence of a large hydrophobe, relatively large blocks of ethylene oxide and propylene oxide [(EO)20-45(PO)20-45] and an electrolyte tolerant end-capping group. These surfactants may be used for both ASP and SP technologies.

Frequently Asked Questions - Enhanced Oil Recovery

Find answers to common questions about enhanced oil recovery

Enhanced oil recovery (EOR) is a set of techniques used to increase the amount of crude oil that can be extracted from an oil field. EOR methods include chemical injection (surfactants, polymers, alkalis), gas injection, and thermal methods to recover additional oil beyond primary and secondary recovery methods.
We offer specialty surfactants for EOR applications that are capable of reducing interfacial tension to ultra-low levels (< 10-4 dynes/cm). Our EOR surfactants feature large hydrophobes, large blocks of ethylene oxide and propylene oxide [(EO)20-45(PO)20-45], and electrolyte-tolerant end-capping groups. They may be used for both ASP (alkali-surfactant-polymer) and SP (surfactant-polymer) technologies.
EOR surfactants provide ultra-low interfacial tension reduction, improved oil recovery rates, enhanced sweep efficiency, better displacement of residual oil, compatibility with ASP and SP technologies, electrolyte tolerance, and improved overall recovery efficiency from oil reservoirs.
EOR surfactants are used in enhanced oil recovery operations, chemical flooding projects, ASP flooding, SP flooding, mature oil field recovery, and various applications where additional oil recovery beyond conventional methods is required.
