Utah FORGE: Hydraulic Fracture Width Determination Using Stoneley Wave Pressure Testing and Electrical Borehole Scans

This report provides insights into Utah FORGE well 58-32's hydraulic fractures. It utilizes both electrical borehole scans from Schlumberger's Formation Micro-scanner Image tool (FMI) and Stoneley waves from a borehole sonic tool. These methods are combined in a comprehensive workflow, leveraging the advantages of each technique to characterize fractures intersecting the well and to estimate their effective width. The report compares separate fracture width estimates from both FMI and Stoneley wave analyses, drawing conclusions about their respective merits. A subsequent workflow was developed where FMI-derived fracture locations informed the Stoneley wave analysis, with results showcased alongside reference FMI images. The culmination of this study is an optimized workflow that offers a robust estimation of hydraulic fracture width, incorporating all collected data.
