Project Red: Monitoring Well 73-22 Geophysical and Mud Logging Data - 2022
This dataset contains open-hole geophysical and mud logging measurements acquired in 2022 from Monitoring Well 73-22 in the Blue Mountain Geothermal Field, Humboldt County, Nevada. Data were collected by Baker Hughes, Baker Atlas, Horizon Well Logging, and other service providers using multiple wireline runs between January and February 2022. Measurements include compressional, shear, Stoneley, and monopole slowness from monopole and dipole acoustic tools; azimuthal anisotropy parameters; gamma ray; multi-depth resistivity; density and neutron porosity; caliper; borehole and mud properties; and dynamically derived rock mechanical properties such as bulk, shear, and Young's modulus, Poisson's ratio, and Gardner's density estimates. A continuous mudlog records lithology, alteration minerals, fracture frequency, and gas content from drill cuttings across the well depth. Files are named after data type and depth interval, each following CWLS LAS formatting with units and null values defined in headers. Some mechanical property datasets note that values are preliminary and not core-calibrated.
