The effects of temperature and of divalent ion concentration on the structure of aqueous surfactant solutions have been determined. As temperature increases, the salinity range...

Two principal types of polymers are currently used for polymer flooding: synthetic polymers called partially hydrolyzed polyacrylamides (HPAM) and a biologically-produced...

Modeling and Optimizing Surfactant Structure to Improve Oil Recovery by Chemical Flooding at the University of Texas DOE/BC/10841-10

DOE/BC/10841-5

Surfactant flooding is flexible because of the ability to optimize formulations for a wide range of reservoir conditions and crude oil types. The objective for this work was to...
