... than estimated based on viscous floods. A numerical model describing diffusion and retention by adsorption was established. A good match between experimental and modeling results was obtained without individually tuning the numerical model for each specific experiment. Additional simulation results...

... fluid chemistry drilling fluids and materials fluid dynamics ppm experiment injection rate breaker in-situ gelled acid permeability Introduction Acid prefers to flow through the high permeability regions of the formation leaving the low permeability regions untreated. Therefore...

... performed using Berea sandstone (8 wt% clays; mainly kaolinite) cores (6 in. length and 1.5 in. diameter). Tetramethyl ammonium chloride (TMAC) and choline chloride were used for comparison as two commercial clay stabilizers. Various coreflood experiments were conducted to determine the effect of the three...

... of the formations. The expected production plateau in this dolomitic carbonate oil field in the south west of Iran is met by Matrix Stimulation. Based on the theoretical improvement of the Pressure Test Analysis (PTA), past experience in the field and reservoir sedimentology, the candidate wells are selected...
