... than the univariate analysis. Besides coal rank, simulation cases were run for different reservoir types, well-patterns, drainage areas, anisotropies, cleat permeabilities, molar compositions of injected fluid and well types. For all these cases, shrinkage/swelling process was also taken into account...

... Abstract A theoretical model of formation force which derives from 3D rock-bit interaction model and weight on bit (WOB) is presented. Except for considering drilling trajectory changes and formation anisotropy, the model accounts for the effects of bit anisotropy and bit tilt angle which did...

... Abstract Well test analysis in naturally fractured reservoirs is generally based on the radial flow model. The radial flow model is however only applicable to purely homogeneous system and long time solution. It cannot provide complete formation analysis in a reservoir that exhibit anisotropy...

... not considered the anisotropy of the media. In previous attempts at anisotropy modeling, the initial anisotropy of the media has been considered, but when it comes to the damage intensity calculation, isotropic parameters have been used for the entire media. As a result, the relative damage in these models...

... to be implemented. The objective of this work is to quantify the effects of directional permeability anisotropy, using Sweep Efficiency and Net Present Value (NPV) as study parameters, on the production performance during a waterflooding under fracturing conditions, in which the injectivity loss is represented...

... Abstract This paper presents the results of a numerical simulation study aimed at evaluating the effect of rock anisotropy on water invasion and oil bypassing in edge-water-drive reservoirs. A complete set of dimensionless groups for 3D immiscible displacement of oil by water in an anisotropic...

... both vertical and horizontal wells; this comprises approximately 25% of the total Unit. The reservoir fluid was characterized using a 9-component Peng-Robinson equation-of-state model. Pattern-based permeability anisotropy was a key parameter used to accurately match individual well response...
