... model, we study practical algorithms of the pressure response, and use methods of numerical integrating and numerical inversion of Laplace transforms to compute typical curves for recognizing flow regimes and ape curve well test analysis. Based on these, this paper further gives expression equation...

... conductivity, etc., can be calculated. This paper shows that the same parameters can be obtained without having to use the type curves. In fact, only the semilog derivative of the data is needed on log-log coordinates. The various flow regimes such as wellbore storage, radial, linear, bilinear or spherical...

... identification of flow regimes more difficult. Thus, a generalized pressure derivative is necessary to simplify the identification of flow regimes in any flow geometry. In this study, a generalized pressure derivative is defined and used to identify the various flow regimes for composite systems in radial...

... angles. With offshore production, however, the occurrence of multiphase flow in highly inclined systems is fairly common. Beggs and Brill l developed a model for predicting a pressure drop and holdup in pipes inclined at any angle between 0 ° and 90 °. The method is flow regime dependent although...

... in the tubing and formation damage. A realistic hot oiling/watering model must consider transient, counter-current heat exchange. The heat transfer coefficients are coupled to changing physical properties of the hot oil/water and changing flow regimes. (The flow regime changes as the annulus fills up...

... part of the test should follow a straight line whose slope can be used to determine flow regime. In a spherical flow the slope is -1.5. The paper also presents application of the radial flow model to surge tests. Several field examples are presented in the paper. Introduction Surge tests...
