| Summary: | The overall goal of this work is to develop and rographics. demonstrate simplified techniques that can be used to estimate the average reservoir pressure, p, directly from the pressure-time profile obtained from a pressure buildup test - without knowledge of reservoir and fluid properties. Musket/Alps Method Our work has resulted in the independent development of a plotting function where the shut-in wellborn pressure, [], is plotted versus the pressure derivative, [] - which yields / from the extrapolation of this trend to []. Arps and Smith originally proposed this work, which was based on an earlier work by Muskat, but our approach is independent and rigorous - we began with the analytical solution for the case of a well in a bounded circular reservoir as proposed by Russell. We have validated this technique using analytical solutions (Appendices A and B), and we have provided a number of field data examples in the body of the thesis. The Musket/Alps technique is well founded in theory and easy to apply - the only negative aspect of this approach is the requirement of very long shut-in times for the simplified solution to be rigorously accurate. Rectangular Hyperbola Method (RHM) We also investigated the Rectangular Hyperbola Method (RHM) approach for estimating average reservoir pressure, and we conclude, based on the comparison of analytical solutions in Appendix B, that the RHM approach is not as consistent, nor as accurate, as the Musket/Alps approach. Based on these observations, we elected not to pursue the application of the RHM approach in this work. |
