Published: 14 May 2015
... for obtaining the slopes of beta-derivatives for transient flow ( m t ) and BDF ( m b ) through a type-curve matching process. The method is validated by comparing results against oil and gas numerical simulations of vertical and hydraulically fractured vertical wells. The developed method is not biased toward...

... in unconventional reservoirs with prevailing transient (linear) flow. Upon selection of an appropriate β BDF (which mainly depends upon the type of flow regime, i.e., radial or linear) and using the proposed equations, type curves can be generated that provide a convenient method for obtaining the slopes of beta...

... water transmission is as follows: Graphing of the Beta curves. This test included measurement of the pipe-to-rail open circuit potential Eo, and the pipe-to-soil potential Vg. These two parameters were measured during the same period of time and the values were plotted together in an x-y graph, where...

A spectrum of simple and common curve shapes, such as coarsening-upward, fining-upward, bell, funnel and cylindrical shapes can be described by two shape parameters, which are referred to as α and β, within a Beta distribution. A numerical method has been developed to fit a Beta...

... Abstract The subject of non-Darcy flow in hydraulically fractured wells has generated intense debates recently. One aspect of the discussion concerns the inertia resistance factor or the so-called beta factor ß in the Forchheimer equation and whether the beta factor ß for a proppant pack...

... (1960) showed beta independent of fluid pressure up to 2000 psi in porous discs. It is now generally accepted that the inertial pressure losses are due to secondary flows which arise from the necessarily curvilinear path taken by the fluid. A similar effect occurs in curved helical tubes (White, 1929...

However, triangular distributions are considered weak by some in that they overweight probabilities towards the tail ends of the distribution. Therefore, in this study, beta distributions were used to allow for the existence of very low probability...

The non-Darcy flow coefficient was correlated with absolute permeability by Janicek and Katz for various limestone, dolomite, and sandstone rocks with porosity as a parameter. They found that beta decreased with increasing permeability...
