Abstract

Summary

inite element method is adopted to simulate the pressure response of wireline formation tester applied to fractured reservoir. The interval pressure transient tests (IPTT) are first used to test the pressure response for both the fractures of crossing and non-crossing well bore in low permeability formation. The simulation results indicate that the fractures crossing the well bore can have large impact on pressure response depending on fractures conductivity. But the effects of non-crossing fractures in the vicinity of the well bore are negligible. The numerical simulation is then applied to analyze the feasibility to evaluate the fractures parallel to well bore with harmonic pulse testing. These results indicate both harmonic amplitude and phase shift are sensitive to the conductivity of fractures in the vicinity of wellbore and demonstrate that the method can be used to evaluate the fracture conductivity efficiently. Finally, we analyzed the effects of pulse frequency and dual probe spacing on the evaluation efficiency.
