Enhanced Oil Recovery

What is Enhanced Oil Recovery?

Enhanced oil recovery (EOR) surfactants mobilize residual oil trapped in reservoir pore networks by reducing oil–water interfacial tension to ultra-low levels—extending field life beyond primary and secondary recovery. Through parent company Harcros, Venus Goa offers patented specialty surfactants for chemical EOR…

What is Enhanced Oil Recovery used for?

Typical Harcros EOR surfactants achieve interfacial tension below 10⁻⁴ dynes/cm at the oil droplet interface. The molecular architecture combines a large hydrophobe, substantial ethylene oxide and propylene oxide blocks [(EO)₂₀₋₄₅(PO)₂₀₋₄₅], and an electrolyte-tolerant end-capping group—technology protected by global… Venus Ethoxyethers manufactures and supplies in India; request a quote for your requirements.

Enhanced oil recovery (EOR) surfactants mobilize residual oil trapped in reservoir pore networks by reducing oil–water interfacial tension to ultra-low levels—extending field life beyond primary and secondary recovery. Through parent company Harcros, Venus Goa offers patented specialty surfactants for chemical EOR programs worldwide.

Harcros EOR surfactant technology

Typical Harcros EOR surfactants achieve interfacial tension below 10⁻⁴ dynes/cm at the oil droplet interface. The molecular architecture combines a large hydrophobe, substantial ethylene oxide and propylene oxide blocks [(EO)₂₀₋₄₅(PO)₂₀₋₄₅], and an electrolyte-tolerant end-capping group—technology protected by global Harcros patents.

ASP and SP flooding

These surfactants are designed for alkali–surfactant–polymer (ASP) and surfactant–polymer (SP) flooding schemes where salinity, temperature, and crude composition demand robust, built-for-purpose chemistries. Laboratory coreflood and phase behaviour screening support field pilot design.
