| Summary: | [ ] The advantage of our approach is that these solutions Again, for comparison, the results from the numerical all of the models are as accurate as the Laplace transform all times of interest. To verify our new P,,CD(tD) models, we applied new modules for the historymatching program (PERANA). appropriate in certain cases. approximate models by assuming the behavior of dimensionless approximate solutions exhibited excellent agreement and are semi-analytical, closed-form solutions. We propose five attempt to develop and apply real time domain solutions for because in most cases the analytical derivatives are too can be used to predict the pressure behavior of a well compare our new solutions to a number of field data cases. consistency with the numerical inversion solution (except for constant rate pressure at the sandface, P,D(tD), as follows: generally better to compute the pressure derivative functions graphical comparison of the residuals for each approximate In order to perform history-matching of our new solutions, as influenced by wellbore storage and skin effects in the real influenced by wellbore storage and skin effects. In inversion solution (as the "exact" solution) and our new inversion solution are used as the base results. In general, Model 2). As a practical consideration, we found that it is numerical inversion solution, though Model I is clearly not numerically, rather than by analytical differentiation, Our objective is to develop approximations of the pressure- particular, we have focused on the cylindrical source relations as the "approximate" solutions. We also provided a solution (as compared to the numerical solution). All of the solution for wellbore pressure behavior that has been solution. As a comparison, we generated the "type curve" solutions for a well in an infinite-acting reservoir with storage and skin effects. Our resulting approximate models tedious for hand calculations. For practical applications, we time behavior for use in analyzing the pressure response of a time domain. To our knowledge, this work is the first used the numerical inversion solution as the exact well as the numerical inversion solution we developed and well in an infinite-acting reservoir influenced by wellbore wellbore storage and skin effects using the numerical |
