Utah FORGE 2439: Well 16B(78)-32 Field-Test Data from Mini-Frac Tests
This submittal includes the field-test data collected during stress tests conducted in the Utah FORGE 16B(78)-32 wellbore to measure/characterize the stresses in the geothermal reservoir. The type of stress test performed is referred to as a mini-frac test or a micro-frac test. The test is a hydraulic fracture test that involves injecting a small volume of water into a short interval of the reservoir that is isolated by a straddle packer to create a fracture. The test provides information about the minimum and maximum horizontal stress at the test depths. A total of seven mini-frac tests were performed within the upper (vertical or nearly vertical) section of the 9-5/8-inch diameter uncased wellbore, between depths of 5,202 ft MD [5,202 ft TVD] and 5,980 ft MD [5966.18 ft TVD]. Two types of data were generated as part of the mini-frac tests. The first type of data is time-series data for each mini-frac test (e.g., injection-rate, test-interval pressure), and are contained in the "Mini-Frac Test Data.zip" file below. The second type is geophysical log data, attached below in the "Geophysical Logs.zip" file. Here, two types of image logs and acoustic logs were obtained before and after the mini-frac tests to examine each test depth for visual evidence of induced fracture(s) and to measure the azimuth (orientation) of any observed fractures. The attached Readme file includes the test depth information and contents of each data file included here. Analysis of the field-test data was conducted and is documented in the attached report below.

"description": "This zip file includes geophysical logs for the Utah FORGE well 16B(78)-32 in Beaver County, UT before and after mini-frac tests. Caliper and temperature logs are also included. The geophysical log dataset includes sonic (XMAC) and image log files taken before and after mini-frac testing by Baker Hughes and covers the depths where the mini-frac tests were conducted. The file formats include .dlis, .las, .cgm, .meta, .tif, and .pdf format. The XMAC logs include compressional and shear wave slowness, Shear-TI anisotropy, CAL, Inversion-fitted travel time delay, compressional wave slowness, horizontal shear wave slowness, Stoneley wave slowness, deep shear wave imaging, and shear radial profile among others. The STAR and CBIL logs provide borehole images before and after the mini-frac tests which allows for fracture analysis. Additionally, temperature data from the first and second logging run are available within the dataset. The baseline logging run occurred on June 23, 2023 spanning 4848 to 9165 ft measured depth and the repeat logging run occurred on July 2, 2023 spanning 4850 to 6150 ft."

"description": "This .zip file includes raw mini-frac test data files at seven test depths within the Utah FORGE 16B(78)-32 well in Beaver County, UT. The mini-frac dataset includes the raw mini-frac test data files (.las format) for each of the seven test depths. Each mini-frac .las file includes the following information collected over the course of each test: system time since record start, quartzdyne gauge pressure, cumulative pump-through volume, depth of 1970DB straddle packer, quartzdyne pressure gauge temperature, packer element pressure, rate (injection and flowback), continuous pump-through volume, and absolute packer element pressure. These tests were conducted over the period of June 28, 2023 to July 2, 2023 in the vertical and slightly deviated sections of the wellbore."
