A successful hydraulic fracturing operation is the key to enable economic production from low permeability reservoirs. A poorly designed operation or problems during the fracturing job would result in a less efficient fracture network contributing to the flow in the production phase. In order to identify problems during the fracturing job and optimize the hydraulic fracturing design for future development, an effective method for monitoring and evaluating the hydraulic fracturing operation is needed. Due to the complex nature of the process, most of the existing techniques for hydraulic fracturing diagnostics and evaluation are limited. In this research, a comprehensive hydraulic fracturing model was first developed to study both pressure and temperature responses during the operation for injection and warm-back, considering the dynamic fracture propagation, dynamic fracturing width growth, and dynamic pressure-dependent fluid leak-off. The model was validated with well-known analytical models. A case study and sensitivity analysis were conducted in the study.A cost-effective distributed microchip sensing (DMS) system for hydraulic fracturing applications was developed and tested under in-situ conditions in this research. Laboratory test results showed that the DMS system could provide reliable pressure and temperature data recorded right at the perforation inside wellbore. The deployment cost of the distributed microchip sensing system would be only a fraction of current measuring techniques, such as fiber-optic sensing. Besides the indirect modeling-based evaluation and direct near-wellbore measurements mentioned above, a direct far-field measurement method was also developed in this research by utilizing the chemical adsorption mechanics. A specially designed surfactant was tested in laboratory experiments for its ability to adsorb on the fracture surfaces. By measuring the adsorbed amount of surfactant on the exposed fracture surface, the total fracture surface area of complicated fracture network can be evaluated using this method. The advantage of this method is it can bypass the difficulties of assuming the fracture geometry and directly translate the fracture surface area into stimulated reservoir volume (SRV). It will be especially useful in naturally fractured reservoirs, where the hydraulic fracture will interact with the existing natural fractures. A dynamic adsorption model was developed for the proposed evaluation method in field scale.Furthermore, a hydraulic fracturing efficiency improvement method was proposed using the same surfactant. An economic analysis was conducted using the comprehensive hydraulic fracturing model developed in this research. The results showed that the efficiency of hydraulic fracturing could be significantly improved using surfactant adsorption.
