...Polymer Properties Grid Dimensions and Layering Abstract This paper discusses the design and implementation of a Single Well Chemical Tracer Test (SWCTT) to evaluate the efficacy of a lab-optimized surfactant-polymer formulation for the Raudhatain Lower Burgan (RALB) reservoir in North...

.... The Apparent Viscosity is the in-situ viscosity of the fluid flowing through a porous medium and is a descriptor of the observed macroscopic rheology of the polymeric fluid in the porous medium. Depending on the extensional properties of the polymer solution, the apparent viscosity can be quite different from...

..., with a resistivity of 18.2 MΩ cm at 25°C. Solutions were prepared and placed at 25°C for 1 day. The compatibility of surfactant and polymer mixtures in brines with different salinities was observed visually. Table 1 Compositions of injection water Composition Concentration (ppm) Na...

.... This behavior of the polymeric chains, in addition to the length of the polymer molecule and the polymer concentration in solution, determine the viscosity of the polymer solution. Some polymers are less sensitive to the ion environment of the polymer solution. For instance, AMPS has a chemical structure...

... sweep with modified brines, given the viscosity and density differences relative to formation brine, requires careful assessment. New polymers and surfactants are expanding the technical window of opportunity, currently chemical EOR in these environments is still commercially challenged. EOR technology...

... processes the steps consist of (1) polymerization from acrylamide monomers; (2) slicing the generated gel bulk volume; (3) drying; and (4) grinding to powder. During the polymerization, polymers with different molecular weight are synthesized resulting in a broad molecular weight distribution. The purpose...

... and extends the results from the earlier papers (( Berg et al., 2015 ; Matsuura et al., 2015 ; van Batenburg et al., 2015 ) and illustrates the role of polymer in ASP flooding. The paper starts with a section that summarizes the experimental set-up and conditions for the different experiments. Results...

...., 1999 ; Denys, 2003 ). Success of polymer-flooding process strongly depends on the propagation of the polymeric solution deep inside the reservoir to maintain mobility control throughout the targeted pore volume ( Szabo, 1975 ; Seright et al., 2009 ; Manichand and Seright, 2014 ). Polymer...
