... using a conventional analytical model. Before analyzing the tests, let's first estimate the times of start and end of flow regimes. The equations for estimation can be referred to a paper by Goode and Thambynayagam (1987) , or a book by Joshi (1991) . The reservoir and fluid properties used...

... Abstract The mechanism of the anisotropic permeability effects on the well patterns and reservoir development are investigated by coordinate transformation, fluid flow analysis, and reservoir development concepts. The Anisotropy of reservoir permeability has destruction and reconstruction...

.... The methodology consists of three steps that are given below. The first step is the ranking of all existing geologic drivers. A fuzzy neural network is used to evaluate the hierarchical effect of each geologic driver on the fractures ( Fig. 5 ). As a result, the geologist or reservoir engineer will be able...

...Conclusions Although horizontal drilling has grown rapidly over the last decade there are still areas where improvements can have vast impacts on successful reservoir production and depletion. In 2000 a technology gap was identified for horizontal wells with open hole completions, where...

.... The goal of cost reduction, which is a major objective in any recovery methods, can be met by using MEOR technology which involves injecting a small amount of a solution containing microorganisms to spread through the reservoir and consequently produce desirable chemicals and gases that will enhance oil...

Abstract A proposal to carry out a well to well chemical tracer test in the pilot area of a field with possibilities to implant an enhanced oil recovery (miscible...

... of the reservoir, maximizing the amount of footage in the reservoir rock. A correction was made in the trajectory around zone E increasing angle from 87° to 89° to gain a little distance from the base and stay sub-parallel to it. If a directional EM measurement had not been available, it is likely...

... A number of practices allow investigating these fluid distributions, essentially using laboratory fluid analysis results. A thermodynamic equilibrium with an equation of state model of the fluid may be derived, which allows predicting fluid phase behavior in the reservoir. Phase transitions...

... Abstract Horizontal well technology has been widely used in developing gas fields. Very commonly, these wells are hydraulically fractured to improve productivity in low permeability reservoirs. A previously developed method, the Distributed Volumetric Source method (DVS), was applied...

... is distributed in the reservoir, we may have a good estimate about maximum and minimum values for porosity in that particular region. So let us assume that porosity is normally distributed with mean 0.21 and standard deviation 0.05. From Fig. 1 , it can be seem that in such distribution, most of porosity values...
