... of these examples obviated the need for a previously ordered service rig. Another example shows how a simple non-quantitative visual scan of the pressure response can be used to immediately recognize problems. (In this case the problem was a severe foam buildup). Some other applications of the method are mentioned...

... 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...

... Abstract A mathematical model is presented to evaluate pressure response of a horizontal well in bounded homogeneous and naturals fractured reservoirs. The model also used to understand the pressure behavior of a horizontal well in an infinite acting, one, two or three sealing faults...

... curves, provides a great improvement in obtaining a unique type curve match. Flow regimes covered in the analysis include infinite acting pressure response with wellbore storage and skin at both the active and observation wells as well as linear flow and pseudo-steady state flow. This study then explains...

... and boundaries into the same pressure profile marking a shift in the fundamental methodology in which data was used in analysis. Prediction of pressure responses from a given flow rate and duration was possible for any hypothetical reservoir model and boundary influence. This prediction was used as the basis...

... Abstract Using the source function approach and the method of images, we have generated the pressure response of a horizontal well in a bounded homogeneous reservoir. Then we have convened the homogeneous solution to the case of a dual-porosity system by means of Laplace transform. Furthermore...

Correa and Ramey2 propose a method by which such tests may be analyzed.) from Fig 2b: The total pressure response is then: c , (P,-P) Figure 1 The principle of superposition allows us to consider this as the sum of two separate buildup tests as shown in Figs. 2a...

..., adequately described by one-dimensional radial flow, a plot of pressure versus logarithm of dme yields a straight line whose slope is related to formation capacity. Transient pressure response is more complex in the case of a PPW. Transient pressure response of a PPW has been extensively studied.1-32 Several...
