Pressure Oscillations Caused by Momentum on Shut In of a High Rate Well in a Fractured Formation
Abstract/Contents
- Abstract
- Pressure transient testing techniques are an important part of reservoir and production testing procedures. These techniques are frequently used to determine practical information about underground reservoirs such as the permeability, porosity, liquid content, reservoir and liquid discontinuities and other related data. This information is valuable in helping to analyze, improve and forecast reservoir performance. A transient well test is performed by changing flow conditions in a wellbore and observing the pressure response. Monitoring of the pressure response may be done at the surface or maybe performed downhole. The data thus obtained is then analyzed by matching the response obtained during the well test with a solution provided by a mathematical, numerical or a physical model. The basic assumption underlying this approach is that the model accurately describes the reservoir behavior. Reservoir properties can be inferred from those used in the model to obtain the match. The well flow rate maybe changed in a number of ways, and each leads to a different type of test. Whether a particular test can be analyzed or not depends upon the availability of a model to describe that particular test. It is thus important to develop models for the different types of well tests and for the different types of reservoirs in which tests are conducted. This report is concerned with developing models for pressure transient well testing in high permeability, high flow rate, naturally fractured reservoirs. Theoretical models presently available are inadequate for handling these well tests because they do not include the inertial effects of the liquid in the wellbore and the fractures.
