... systematically at laboratory scale, consisting of polymer, cross linker and nanoparticles (silica dioxide). The gel system was characterized by different parameters like viscosity (μ), loss modulus (G″) and elastic modulus (G′) by varying polymer concentration, cross-linker concentration, silica dioxide (SiO 2...

... compatibility tests, interfacial tension tests, viscosity measurements and coreflooding experiments. Hardbrine composition of 59,940 ppm was used to prepare the ASP formulations in the presence and absence of AA. All the chemicals including, alkalis, surfactants, and polymers were compatible with the hard brine...

... on that specific case. Data used for this comparative analysis included; well depth, deviation, overbalance; formation type, temperature, pressure; mud weight, funnel viscosity, Fann viscometer readings, gel content etc. Graphical analysis was performed for 26 jobs by plotting all these parameters and common...

..., Liquid drop-out, Condensate viscosity and Compressibility, while the rest yield minimal impact. The VPR models also improve history matching and give better forecast; while using pseudo-pressure approach reduces significant time with negligible impact on the results. GAS COMPRESSIBILITY (Z) FACTOR...
