... tension (IFT) and flow based on a set of stick relative permeability curves. The viscous force mainly dominates the flow of two liquid hydrocarbon phases as the density difference between two liquid phases is relatively small. Hence, the gravity effects on the flow is neglected. The flow of each...

... Abstract Physics of multiphase flow in porous media heavily relies on the concept of relative permeability. Moreover, relative permeability is an important input parameter for any numerical reservoir simulation representing multiphase flow in porous media. Relative permeability curves are also...

... storage site should be kept away from wells that have a surface casing depth of 476 ft or shallower and were drilled before 1994 in Colorado. The effective well permeability highly impacts the leakage rate, implying the importance of estimating the most representative value/range for this parameter...

... of the study revealed that iron (III) precipitation is an obvious threat causing severe formation damage in carbonate rocks by significantly decreasing the rock permeability. Adsorption of chelating agents on limestone rocks highly depends on their concentrations. Specifically, an increase in the concentration...

... statistically summarizes results from 83 of these DFITs, submitted by many operators from the Canadian Duvernay shale play. The main parameters analyzed were closure, reservoir pressure and permeability. This newly updated directive sets out requirements for pressure and deliverability tests...

... permeability and gas adsorption on the variations of two master curve scaling parameters, the gas mass in the stimulated reservoir volume ( M SRV ), and the characteristic pressure interference time (τ). GSA using a reservoir simulator is prohibitive. Therefore, we implement and validate a Gaussian process...

... potential of unconventional reservoirs, forecasting future production accurately using Arps decline models becomes more challenging because of the complicated fluid flow mechanisms characterizing stimulated multi-layered ultra-low permeability porous media. Many field studies indicate unreliable forecasts...

.... The existence of pinch points makes the fracture conductivity segmented, and the partial closure of fracture can be simulated by setting different fracture lengths, widths, and permeability. The flow in each region is treated as the linear flow and is coupled through boundary conditions and flux supply. Thereby...

As we would expect, wells with the most pay thickness, greatest permeability along with relatively higher pore pressure, effective porosity and low water saturation have the greatest potential for hydrocarbon production. The most productive completion types...

In Coreflow testing, the non-corrosive deep penetrating acid is effective to stimulate sandstone and provides remarkable permeability improvement by at least 60% at 475°F. Because of the in-situ controlled generation of HF, it penetrates deeper in the formation...

.... The FTWD direct formation pressure and mobility measurements enriched the understanding of the reservoir by establishing pressure gradients. By interpreting the results of the selected points, reservoir zonation was estimated based on the calculated mobility, which indicated a high degree of permeability...

... Abstract High permeability zone (HPZ) formed by sedimentation and diagenesis has been founded in numerous oil fields in Middle East. Meanwhile, horizontal well have been applied universally in these oil fields. To obtain wellbore status and reservoir properties, pressure transient analysis (PTA...
