Abstract:

This presentation reports that a suitable matrix-fracture shape factor function is required for the accurate flow behavior prediction in a dual-media system for the thermal recovery mechanisms in fractured reservoirs. The concept of a new transient shape factor model for a non-isothermal, dual-porosity model is introduced and compared with the common existing shape factor formulations. The transient shape factor (TSF) formulation was developed and validated for thermal recovery processes. The results from this study clearly confirm that a transient shape factor is required for an appropriate modeling of thermal recovery methods using dual-media formulations. Gilman and Kazemi’s model was evaluated, but this methodology can be used to investigate other shape factor formulations as well.
