Abstract: Systems and methods presented herein are configured to predict fracture height and reconstruct physical property logs using models based on machine learning algorithms and physical diagnostic measurements. In particular, physical diagnostic measurements may be used to train machine learning algorithms that can be used to predict the existence of a fracture as a function of depth. For example, physical diagnostic measurements collected by downhole sensors can be used to train the machine learning algorithms, which may then be used to predict the existence of a fracture as a function of depth based on subsequently collected physical diagnostic measurements, for example, to determine fracture height of the fracture.

Abstract: A method and a system for volume-based proppant trapping along a fracture surface is disclosed. Hydraulic fracturing involves injecting proppant to ensure separation of the fracture surfaces after the stimulation treatment is completed. The spatial placement of proppant is assumed to be directly related to the fracture conductivity along the hydraulic fracture as well as its connectivity to the wellbore. Fracture conductivity is an important focus of designing fracture treatments since fracture conductivity may be directly related to the well performance. Thus, improving one or more aspects of proppant placement, such as determining the optimal type, size and/or concentration of proppant(s) may enhance fracture conductivity and in turn improve well performance. In order to understand the placement of proppant in the subsurface, a volume-based proppant trapping model is used. The volume-based proppant trapping model may factor in parameters associated with the subsurface, parameters associated with the proppants, and user parameters, such as the total volume of proppant along the fracture surface, thereby assisting in hydraulic fracturing.
