Abstract

In this paper, well test data from three naturally fractured oil reservoirs were analyzed based on conventional semi – log plots, type curve matching, and Tiab’s direct synthesis techniques. A computer program using C# was developed based on the direct synthesis method to be used in analyzing well test data in naturally fractured reservoirs. The developed program gives accurate results compared with pan-system (one of the commercial softwares) which characterizes the naturally fractured reservoir using conventional semi-log and type curve matching techniques. The developed program characterizes the fractured reservoir in case of the infinite reservoir without wellbore storage effect whether all flow regimes are present, the early time infinite acting radial flow regime is absent, the late time infinite acting radial flow regime is absent or both infinite acting radial flow periods cannot be observed.
