Assessment of the potential of a polymer flood for mobility control requires an accurate model on the viscosities of displacement fluids involved in the process. Because most polymers used in EOR exhibit shear-thinning behavior, the effective viscosity of a polymer solution is a highly nonlinear function of shear rate. A reservoir simulator including the model for the shear-rate dependence of v...

Accurate prediction of petroleum reservoir performance requires reliable models of the often complex reservoir heterogeneity. Geostatistical simulation techniques generate multiple realizations of the reservoir model, all equally likely to be drawn. Traditional to geostatistics, geological continuity is represented through the variogram. The variogram is limited in describing complex geological...

A pilot study of 13 wells in Means oil field of the Permian basin, West Texas, established porosity-permeability relationships for the Permian Queen, Grayburg and San Andres formations. The optimized workflow used borehole image and conventional log processing with calibration to core data. This approach allowed the quantification of porosity and perme-ability heterogeneity in vuggy carbonate f...

Recovery efficiency is a key factor in decision-making oil and gas projects. Although structural setup well type considerably influence waterflood recovery, few studies have explored the performance of highly deviated wells during waterflooding complex shallow reservoirs. Here, we applied numerical simulations to investigate vertical, horizontal, multilateral, reservoirs using J1 Oilfield as ca...

Abstract Carbonate reservoir has complex pore structures. At present, the influence of structure on water flooding mechanism carbonate reservoirs is insufficient. In this article, a systematic workflow was designed in combination with scanning electron microscope, particle size, physical properties, and experiments to study effect fine-grained rocks. Due small size strong heterogeneity, acid fr...
