• Hydraulic Fracture Width Inversion Using Simultaneous Downhole Tiltmeter and Distributed Acoustic Sensing Data 

    A new geomechanical modeling approach is presented to estimate hydraulic fracture width based upon joint inversion of near-field and far-field slow deformation data measured, respectively, by Distributed Acoustic Sensing (DAS) and Downhole Tiltmeter Fracture Mapping (DTFM) systems. By substantially reducing the non-uniqueness of possible interpretations, integrating simultaneous deformation measurements allows the authors to resolve the fracture opening with higher confidence and resolution. They provide a step-by-step modeling workflow, verify their approach using synthetic data, and quantify the uncertainty. The resulting correlation between fracture opening and fiber strain can then be applied to other stages in the treatment well that fall outside the detectability range of DTFM and only have fiber data available. 

    This presentation is from the 2022 SPE Hydraulic Fracturing Technology Conference and Exhibition.
