Improvement solution of oil recovery coefficient by the technology of nano-surfactants complex flooding

Code: 001
Title of technology/equipment: Improvement solution of oil recovery coefficient by the technology of nano-surfactants complex flooding

Countries Technology offering : VN Việt Nam
Index classification SPC : Chemicals, chemical products and man-made fibers

Description:

Uses:

Enhanced oil recovery by injection nano-surfactants complex due to reducing surface tension, having good wettability properties and changing in wettability between oil and rocks. Nano particles and surfactants have 2 bonds: hydro bonds and covalent bonds, thus heat resistance will be increase and viscosity of nano-surfactant flooding is improved

Advantages

Areas of application:

Technology of additives for polymers and polymer products manufacture

Development status: Commercialized

Advantage :

Surfactant flooding are not effected by the water mineral compositions, surface properties of the rocks, for example, salt precipitation, reducing activity of the surfactants and strength at high lalinity and temperature (130⁰C)

It is quite important to apply nanopracticles in injection flooding with various types and unique sizes, specially surface modification of nanoparticles of the rocks and improve the dispersion stability of nanoparticles
