... gas reservoirs. Injection of proppant particles with increasing size and decreasing concentration results in deep percolation of proppant into the natural fracture system, expansion of the stimulated zone and increase of well productivity index. A modified mathematical model for well indices during...

... as well as to increase hydrostatic pressure, resulting in reduced surface pressure. This paper investigates the effect of salt concentration on reduced viscosity for different types of polymers used in fracturing fluids. Different polymers, such as guar, hydroxypropyl guar (HPG), carboxymethyl...

... test represent the output. Experimental data for building the ANN model was obtained by performing approximately 150 standard shale-erosion tests using five different shales with varying mineralogy and WBMs with varying salt concentrations/types, shale stabilizers, and mud weights. For every test...
