This report documents the post-hydraulic fracturing extended circulation test between Utah FORGE wells 16A and 16B conducted in August 2024. In well 16B, fiber optic measurements of Rayleigh frequency shift distributed strain sensing (RFS-DSS) and distributed temperature sensing (DTS) were primarily used to detect and map thermal inflow anomalies, as detected by thermally driven strain changes and thermal changes. The report provides a first pass integration of SLB Production Logging Tool (PLT) results with fiber optic results to look for correlations between the two different types of data. The report also takes a close look at the fiber optic derived cross well strain signatures created during fracturing of 16A, as detected at the 16B producer well and correlates those fracture driven interactions with the circulation flow test results.

This report examines the fiber optic measurements made on the Utah FORGE well 16B(78)-32 after it and well 16A(78)-32 were hydraulically stimulated and shortly thereafter a 9 hour cross well circulation test was run between them. The report reviews distributed fiber optic signal processing and analysis using Rayleigh Frequency Shift - Distributed Strain Sensing and Distributed Strain Sensing (RFS DTS) data. The data are integrated with pumping and discharge rate data from the two wells. All data are depth registered to Measured Depth (MD) Relative to Kelly Bushing (RKB).

This zip file contains reports discussing the use of fiber optics during well 16B(78)-32 stimulation and circulation tests in the summer of 2024. The reports cover the collection of strain rate and temperature change data during these well events. Theory, methods, and initial data visualizations are included in the reports, highlighting the value of these data types.

This dataset contains processed fiber optic measurements collected during the extended cross-well circulation test at the Utah FORGE site in August 2024. The data was acquired from the 16B(78)-32 well using distributed fiber optic sensing (DFOS) technology, including distributed temperature sensing (DTS) on multimode fiber and distributed strain sensing (DSS) measurements on single-mode fiber. The dataset includes Brillouin absolute strain, Rayleigh frequency shift (RFS) DSS strain change, RFS DSS strain change rate, and temperature (DTS) data, all stored in HDF5 format. Time coordinates are provided in UTC, and depth measurements are given in measured depth relative to the rotary kelly bushing (MD RKB) in feet. The spatial sampling on the RFS DSS strain data and the Brillouin Absolute Total Strain data is 20 cm and the spatial sampling on the DTS data is 1m. The dataset is accompanied by a report from Neubrex, which provides further documentation.

This dataset features Distributed Acoustic Sensing (DAS) and fiber optics monitoring data acquired by Neubrex Energy Services during the Utah FORGE Well 16B(78)-32 circulation test in July 2023. DAS and fiber optic monitoring data include absolute strain, strain change, strain change rate, distributed temperature sensing (DTS), and frequency band extraction (FBE). Data processing was completed between September and October 2023. The dataset includes the fiber optic sensing data collected during these operations, along with a data collection report, descriptions of the data, and instructions for reading the data files.

Included here are two fiber optics monitoring reports on Utah FORGE well 16B(78)-32 from Neubrex Energy Services. These reports review the fiber optics monitoring during both the cementing and circulation test periods of the well. Cementing as well as post-cementing monitoring and circulation testing occurred from July 13th to July 20th of 2023. Reports detail the data collection process and provide relevant findings in a presentation format. Well 16B(78)-32 serves as the production well for the Utah FORGE enhanced geothermal system (EGS).
