The rheological behavior of microemulsion systems was systematically investigated with
mixtures of oil, brine, surfactant, cosolvent, and in some cases polymer to determine their …

A predictive model was developed that captures quantitative structure-property relationships
between the molecular structures of surfactants and co-solvents and microemulsion phase …

Cold production is a challenge in the case of heavy oil because of its high viscosity and poor
fluidity in reservoir conditions. Alkali–cosolvent–polymer flooding is a type of microemulsion …

Scientific understanding of how the molecular structures of surfactants and cosolvents affect
microemulsion properties greatly speeds up the process of arriving at optimal chemical …

The chemical cost to recover an incremental barrel of oil is directly proportional to the
surfactant retention, so the single most effective way to reduce the cost is to reduce …

We made measurements of microemulsion rheology with mixtures of oil, brine, surfactant, co-
solvent, and in some cases polymer to systematically investigate the effects of salinity, co …

Abstract Alkaline-surfactant-polymer (ASP) coreflood experiments using Indiana limestone
were conducted to test the effectiveness of sodium hydroxide in reducing surfactant retention …

Waterflood oil recovery in many carbonate oil reservoirs is low due to both high residual oil
saturations and low sweep efficiency because of high heterogeneity. An example is the …

Optimizing macroscopic properties of microemulsions (volume, composition, and viscosity)
is tedious and often involves the use of an alcohol. We show that this optimization is …

The objective of this research was to develop a model to predict the optimum phase
behavior of chemical formulations for a given oil based on the molecular structure of the …
