  • SYSTEMS AND METHODS FOR HYBRID MODEL HYDRAULIC FRACTURE PRESSURE FORECASTING
    Publication number: 20230417950
    Abstract: A system for determining pressure in a hydraulic fracturing system for a well includes a processing module executing code and configured to receive a plurality of input parameters. The processing module can predict either a bottomhole pressure, based on statistical predictions and physics-based predictions, or a surface pressure based on the predicted bottomhole pressure.
    Type: Application
    Filed: September 7, 2023
    Publication date: December 28, 2023
    Inventors: Leen Weijers, Andrew Bonnell, Ely Lolon, Zhijun Liu, Karn Agarwal, Robert Henderson, Michael Mayerhofer
