The Use of IMEX in Well Testing Applications
Introduction

This document describes some guidelines for the use of IMEX in simulating well tests. Such tests typically call for a well to be operated at a sequence of different flowing conditions, usually involving high rate withdrawals followed by shut in periods, under careful pressure monitoring. This monitoring is done with (electronic or mechanical) down-hole gauges placed in the wellbore of the well undergoing the test, and sometimes in the wellbores of selected neighboring wells. The single well test is most often encountered (no neighbor monitoring, or no neighbors), although multi-well interference testing is also done. The resulting down-hole pressure history is analyzed to obtain an indication of the reservoir’s character. The analysis hopes to recover at least the reservoir’s permeability-thickness product as well as other information regarding well properties (such as damage and the presence of near wellbore fracturing). Certain reservoir parameters, such as the Warren and Root model’s LAMBDA and OMEGA parameters for multiple porosity reservoirs, are also sought. The reservoir analysis is carried out with the aid of specialized graphical presentations. These graphical techniques have been well developed over time and are derived from the consideration of simplified reservoir and wellbore models.
