EGS Collab: Hydraulic Fracturing Test Measurements on the 4100L of SURF
This package includes data from two days of testing at the Sanford Underground Research Facility (SURF) on the 4100 level. The tests were performed in borehole TV4100 in the battery charging alcove south of the Yates shaft. TV4100 is a vertical borehole ~50 meters deep. A series of hydraulic fracture (mini-frac) and reopening tests were conducted at various depths to investigate the magnitude and direction of the minimum principal stress in that area of the mine. Apparent features of the pressure time/pressure injected volume curves are the onset of fracture, peak pressure, and the initial shut in pressure (ISIP).
The raw data files include a Readme with the day, time, and location of each file. The files are organized into 9 columns: time (sec), flow meter (V), Pressure of Return (V), Pressure of Packer (V), Pressure of Injection (V), flow (gpm), Pressure of Return (psi), Pressure of Packer (psi), Pressure of Injection (psi). The shift reports are a short log of how the tests were run in the two-day period. An American Geophysical Union (AGU) 2019 presentation by Ingraham et al. is shown to provide visualization/interpretation of the data. The columns which report voltage (V) show the unscaled voltage value from the transducer, which was recorded in case pressure values needed to be rescaled due to incorrect calibration factors. This was not necessary.
Results reported in the AGU poster were filtered with a moving average to remove pump noise before presentation. Note that the logging and impression packer results are included in separate datasets managed by Lawrence Berkeley Laboratory.
