Fault effects on pressure derivative curve analysis on well test: A case study

This study aimed to Investigate the fault effect, and reservoir rock and fluid properties on the pressure derivative curve as an approach of well test investigations. For this purpose, the simulation of the case studied reservoir was done using Eclipse ۱۰۰ software. According to the results, Slope of the IARF regime to LSF regime was doubled; Also, the closer the well is to the fault, the faster the fault has its effect. When the porosity increased, the well felt the effect of the fault later. Based on simulation results, when the permeability decreased, the slope is directly affected by the fault; Also, when the Fault transmissibility increased, the graph no longer followed the doubling slope and stabilized at a lower slope; as well as, the ISF caused the slope of IARF to quadruple.
