Automated Well Test Analysis Using Pressure Derivative
Abstract/Contents
- Abstract
- This report studies the simultaneous use of pressure and pressure derivative in automated well test analysis. The study has shown that the combined derivative method is only useful in graphical techniques, in which the conventional type curves are not well defined. Adding the derivative helps remove the ambiguity and enhance the resolution. The automated well test analysis uses a non-linear regression algorithm to compute the whole curve and minimize the deviation from the measured pressure data. The objective of this work was to determine the effects of minimizing the deviation from the pressure derivative at the same time. It was found that adding the derivative only increases the error and does not improve the solution.
