Abstract

It is difficult to identify the mechanics of an underground reservoir and is even more difficult to identify the qualities of sites that have unusual forms. Pressure transient analysis is a tool that helps to understand what is happening inside the reservoir, understand the flow mechanisms at a macro level, and sometimes, however, they are not enough to identify flow channels generated by complex fault systems. Currently, there is not a methodology to characterize either wedge or T-shaped deposits by pressure transient testing. Then, this paper contains a careful analysis of different pressure behaviors on such systems, so numerical simulations were run for reservoirs systems considering T and wedge geometries having a well inside them in a variety of locations. The final product consists of developing an interpretation methodology using the pressure and pressure derivative log-log plot to characterize these types of reservoirs. The developed equations were succesfully tested with synthetic examples.
