Cape EGS: Gold 4-PB: Mudlog, Mass spectrometry, Triple combo, and Dipole sonic-derived geomechanical data

1. Mudlogs
Mudlogs provide lithological information based on the analysis of drill cuttings and observed drilling parameters. These logs allow for the identification of formation changes, rock types, and basic mineral composition. They offer a continuous lithostratigraphic record that is essential during active drilling and for initial formation evaluation.
2. Mass Spectrometry Logs
Mass spectrometry logs are used to analyze mud gases to determine the types and concentrations of gases released from the formation and fractures during drilling. This technique helps identify active gas-bearing zones and provides high-resolution insight into fluid presence and movement, offering greater detail than traditional total gas measurements.
3. Triple Combo Logs
Triple combo logs contribute to lithological and petrophysical analysis by measuring formation density, porosity, and resistivity. These properties enable differentiation between rock types, identification of porous zones, and assessment of fluid content?helping to refine the subsurface model and inform completion and stimulation decisions.
4. Dipole Sonic and Geomechanical Logs
Dipole sonic logs measure the propagation of compressional and shear acoustic waves through the formation. From this data, geomechanical properties such as dynamic Young?s modulus, Poisson?s ratio, and rock stiffness are derived. These measurements also reveal anisotropy related to natural fractures and in-situ stress conditions. Together, the data are used to evaluate fracture behavior, mechanical stratigraphy, and wellbore stability, forming a critical input to stimulation design and reservoir modeling.
