As we continue to develop the processes of hydraulic fracturing in tight, naturally fractured, reservoirs, so continues our development of more effective bottomhole treating pressure (BHTP) diagnostics. New diagnostic techniques need to reflect the physical processes and give insight to potential damage mechanisms prevalent during hydraulic fracture treatments in these complex reservoirs. In this paper, we provide a thorough evaluation of BHTP trends observed during fracturing treatments performed in the Barnett Shale, a naturally fractured shale reservoir. From this evaluation, we are able to propose a new, more effective tool that can be combined with other BHTP and fracturing diagnostic techniques. Further, this analytic technique is easily adaptable to the treatment of other tight, naturally fractured reservoirs to enhance design or on-site decisions.
