Well 16B(78)-32 Planning Video: This is a YouTube video containing the specifics of well planning for Utah FORGE 16B(78)-32. This well will be drilled as a doublet approximately 300 feet parallel to and above 16A(78)-32. This video discusses topics such as: seismic mitigation; improving well quality; operational and scientific objectives; well design; instrument cable protection; stress measurements; the coring program; drilling site geology; well logging; well stimulation and fracture intersections; borehole cooling; and instrument installation. This well will be drilled between approximately April 15th and July 17th 2023.

4. Sanvean Technologies Drilling Data from Well 16B(78)-32. Sanvean Technologies bit sensor data amalgamated with NOV Blackbox data for Reed Hycalog bits used during drilling of Well 16B(78)-32. This dataset contains information, collected at the bit while drilling, such as rate of penetration (ROP), top drive torque, and bit box temperature. The data was recorded at the bit box and top sub of the motor. RPM was measured by onboard gyro recording continuously in each sensor, shock levels were also recorded on X, Y and Z axis. This data was merged with EDR in time format and saved in file sets (the zipped files) then output into CSV files. Please note: fields in the CSV files, such as the date field, may need to be formatted to display properly. There is an additional zipped folder in each dataset that is password protected. Sanvean GameChanger Viewer software must be used to view this data. A pdf file is included describing this software. More information in this regard can be seen at: https://sanveantech.com/products-services/downhole-data-analysis. This data also includes a report on the analysis of the drill bit sensor.

The data consists of time series pressure-temperature data and plots from March 26th - April 20th 2024.
10. Well 16B(78)-32 Reinterpretation of Thrubit FMI log This file is a reinterpretation of the trip 3, Thrubit FMI log from well 16B(78)-32, that covers measured depths 6,252 to 10,914 ft. This differs from the previous version in that it includes interpreted tensile induced fractures.
11. Well 16B(78)-32 Drill Core Fracture Analysis Images and Data This is a set of drilling core data from well 16B(78)-32 containing (1) pdf documents with flattened core images and annotated feature types by core interval and (2) spreadsheets with feature morphologies by depth; as measured planar features; and planar feature rotated to in situ orientations.

Core was recovered from three intervals in 16B(78)-32, one per stimulation stage, in the crystalline rocks that had been impacted the stimulation of 16A(78)-32. Seven core runs were made with 135.8 ft of core recovered.

Features in the core were assigned to one of the following categories:

1 Planar fractures

2 Semi-planar fractures

3 Unbroken mineralized fractures

4 Rough Fractures

5 Curviplanar fractures

6 Concave-convex surfaces

7 Planar compositional features (mylonite or dike?)

Planar features in the core were measured while the core was lying horizontally with the axis of the core having a downhole azimuth of 42 degrees.

Planar core measurements from stimulations 2 and 3 that could be confidently matched to FMI images/data were rotated to in situ orientations by:

1. Rotating the planes along vertical and horizontal axes to match the azimuth and inclination data recorded in the directional survey of ::well 16B(78)-32.

2. Applying an axial rotation to resemble the fracture orientations observed in the FMI log at corresponding depths.

Coherent sets of planar fracture measurements were made by aligning the core within each 3 ft section of the dissected core barrel, and between adjacent 3 ft sections within a core run by matching rock fabrics, saw cuts and/or tool marks. Where coherent fracture measurements would not be made within a core run, data sets are denoted by a subscript (i.e. 2-Ta and 2-Tb both come from tangent core run number 2).
