... recovery, which were slightly higher than that in the CG flooding. In linear cores, the gravity segregation effect is limited due to the small diameter of cores; so, the extent of bypassing is small. In heterogeneous cores, there is bypassing in CG floods due to permeability contrast and WAG / PAG floods...

..., and quantifying the level of CO2/gas condensate interactions. A CO2 H-n-P injection core-flood simulation model was developed. H-n-P injection cycles with the incremental injection of CO2 volumes were simulated to replicate experimental procedures performed on a high-permeability Berea sandstone core...

... samples by inhibiting 84% and 85% of iron (III) ions, respectively. The encountered permeability damage in the adsorption tests was between 25% and 32%. Moreover, the presence of the salts considerably decreased the adsorption of EDTA and caused almost 20% more permeability reduction. Unlike...

... Abstract It is widely recognized that hydraulic fracturing creates a region of altered permeability near the fracture/matrix interface. Although we have a limited understanding, it is believed this region plays an important role on the production rates. The objective of this study is to model...

... the open hole into the reservoir. Based on the analysis, the most likely cause of the strange packing behavior was the combination of low screen inflow area, relatively low gravel permeability, higher fines content in the natural gravel sand and high gravel carrier fluid viscosity, which resulted in a high...

... tends to be characterized as high in-situ stresses, fissile, laminated, with low permeability. It has been observed that wellbore stability problems occur due to lack of appropriate inhibition from drilling fluids. The most important variable in maintaining shale stability is the prevention of pressure...

... Abstract During the reservoir depletion and injection operations, the net effective stress is disrupted due to pore pressure changes. As a result, the reservoir properties, mainly porosity and permeability, are influenced by the change in the stress behavior in the reservoir rock. Understanding...

... Abstract The Sparky/General-Petroleum/Rex/Lloydminster formations are subject to a mature waterflood (1300 + vertical/horizontal wells) in Chauvin, Alberta, where permeabilities and viscosities range from 10 to 200 mD and 40 to 150 cp, respectively, and adverse mobility ratio, injection...
