Reservoir Characterization and Depositional System of the Atokan Grant Sand, Fort Worth Basin, Texas
<p>The Atokan Grant Sands are a tight gas sand play that would add new reserves to the Fort Worth Basin. The Fort Worth Basin is located in north-central Texas just west of Dallas, Texas. Within the basin, the study area consists of Denton, Wise, Tarrant, and Parker Counties in Texas. The basin is …

Investigation of fluids flow behavior in nano-scale channels by using optic imaging system
"Tight gas and shale gas reservoirs are characterized to have small pores with diameters in nanometer (nm) range. The physics of fluid flow in nanopores is poorly understood. Knowing the fluid flow behavior in the nano-range channels is of major importance for stimulation design, gas production …

Characterization of Filter Cake Buildup and Cleanup under Dynamic Fluid Loss Conditions
… fracturing is a popular stimulation method in tight gas and shale gas reservoirs that uses a viscous fluid to fracture the reservoir rock and uniformly transport proppant to create a highly conductive path that is kept open by the proppant after fracturing. This method is used to improve the …

Modeling of Real Gas Flow Behavior in Porous Media
Due to the highly nonlinear variation of gas density and viscosity with respect to pressure, no analytical solution to the real gas diffusivity equation has ever been presented in the literature. Analytical solutions used in gas well testing and pressure analysis are based on idealized assumptions, …
