(591e) Handling Microseismic Measurement Uncertainty in Fracture Geometry Control of Hydraulic Fracturing
Motivated by this unique nature of MSM, we propose a novel control framework for measurement uncertainty reduction while simultaneously accomplishing the original control task of achieving the desired fracture geometry in hydraulic fracturing. Initially, a novel high-fidelity model is developed to describe hydraulic fracturing as well as the dependence between the fracturing fluid injection rate and measurement error. Then, open-loop simulation results from the high-fidelity model are used to develop a reduced-order model for a Kalman filter. Then, a model-based feedback control system is proposed using the Kalman filter to achieve both the measurement uncertainty reduction as well as propped fracture geometry control, by manipulating the fracturing fluid pumping schedule which includes the fracturing fluid injection rate and proppant concentration at the wellbore. Closed-loop simulation results are presented to show that the proposed technique outperforms conventional techniques employed in the shale reservoirs.
