Cape EGS: Gold 4-PB: Mudlog, Mass Spectrometry, Triple Combo, and Dipole Sonic-Derived Geomechanical data
This dataset includes geological and geophysical well logs from the Gold 4-PB well at the Cape EGS site near Utah FORGE, collected between December 2024 and January 2025. The dataset covers lithological, geochemical, and petrophysical data acquired during and after drilling. Data types include mud logs, mass spectrometry logs, triple combo logs, and dipole sonic logs with derived geomechanical properties.
Mud logs provide a continuous lithostratigraphic profile from drill cuttings and drilling parameters, identifying rock types and mineral content. Mass spectrometry logs capture depth-resolved gas compositions emitted during drilling, offering detailed insight into hydrocarbon presence. Triple combo logs record formation density, porosity, and resistivity to support subsurface characterization. Dipole sonic logs and associated data derive compressional and shear slowness to compute geomechanical properties such as dynamic modulus, Poisson?s ratio, and stress anisotropy.
