Impact of natural fractures in drainage volume calculations and optimal well placement in tight gas reservoirs

We demonstrate the power and utility of our method using both synthetic and field applications. The synthetic example is used to validate our approach by establishing consistency between the drainage volume calculations from streamlines and the EUR computations based on detailed finite-difference simulations. We also present comparison of our approach with analytic drainage volume calculations for simplified cases. Finally, we present a field example whereby we utilize the streamline-based drainage volumes to identify depleted sands and generate a reservoir 'depletion capacity' map to optimize infill well placement based on the undepleted and undrained regions. The field application clearly demonstrates a systematic approach to optimal well placement in tight gas reservoirs.
