Utah FORGE: 16B(78)-32 RFS DSS Strain Change Rate and Selected FDIs During 16A(78)-32 Stimulation

This dataset contains strain change rate versus depth data acquired using a Rayleigh frequency shift (RFS) distributed strain sensing (DSS) system during hydraulic stimulation of well 16A(78)-32 at the Utah FORGE site in April 2024. The data were collected from an optical fiber installed in the annulus of production well 16B(78)-32, approximately 300 feet from the injection well. The dataset includes tabulated strain data, documentation of the methodology used to generate a frac log by integrating strain change rate signals over selected time windows to identify fracture events, and a spreadsheet of selected Fracture Driven Interactions (FDIs) identified from the same measurements.

The FDIs were derived from cross-well RFS DSS observations while stimulating well 16A(78)-32 and monitoring strain rate in well 16B(78)-32 using fiber cemented behind casing. Selected FDIs were high-graded and used to inform perforation cluster placement for stimulation of well 16B(78)-32, with selections made by Utah FORGE representatives under the guidance of Neubrex Energy Services (US), LLC, and a fiber installation consultant. Together, the dataset documents the acquisition, processing, and interpretation of cross-well strain measurements used to identify fracture-related strain features over approximately 1100 ft of the monitored wellbore.
