EGS Collab Experiment 2: Shear Stimulation ERT Monitoring Data

Description

This repository contains the electrical resistivity tomography (ERT) monitoring data that was collected before, during, and after shear stimulation attempts were conducted at EGS Collab. These tests were carried out on the SURF 4100 level during Experiment 2 in March, 2022. Flow and stimulation data corresponding to this dataset are available in a different GDR dataset, which is linked below. Also included here are the E4D input files that were used to process the ERT data. E4D is an open source ERT monitoring and inversion code which is linked for use below.

46 This houses the E4D input files used to invert the time-lapse ERT monitoring data collected during the Experiment #2 shear stimulation tests. https://gdr.openei.org/files/1480/E4D_FILES.tgz
21 This is a link to the open source E4D ERT modeling and inversion code's website. E4D is a scalable, 3D geophysical modeling and inversion code that uses geophysical measurements to generate subsurface images. The code can be used to process this ERT data via the E4D input files in the adjacent resource. https://www.pnnl.gov/projects/e4d
46 This is the complete time-lapse ERT dataset collected during the shear-stimulation attempts, where hydraulic pressure was applied to well E2-TC. ERT data were collected using the 8 following wells: AMU, AML, DMU, DML, TU, TL, TN and TS. https://gdr.openei.org/files/1480/8_Well_shear_stim_monitoring.tgz
21 This is a link to results from the hydraulic pressure/shear stimulation test, during which the ERT data was collected. The goal of the test was to use hydraulic pressure to cause shear slip on preexisting fracture or fault planes such that the hydraulic conductivity of the fracture or fault increases. https://gdr.openei.org/submissions/1476
