Function

The Petrophysics lab is used to measure the physical properties of rocks and sediments. These properties are indicators of composition, formation, tectonic regime, and environmental conditions of the deposits. Some properties can be measured rapidly at high spatial resolution and serve as proxies for processes such as paleoclimatic change. Because physical properties are usually well defined and quantitative, they help constrain the complex mineralogical and fluid systems in rocks and sediments.

Instruments

Section-half measurements:

  • Contact-based P-wave velocity (bayonet PWS1/2 and caliper PWS3) (Quick Start guide; User guide; Cumulus)
  • Automated vane shear (AVS) for shear strength determination (User guide; Cumulus)
  • Helium pycnometer for volume determination (Quick Start guide; User guide; MADMax Quick Start guide; Cumulus)
  • Mettler-Toledo XS204 dual-balance system for mass measurements (User guide; Cumulus)
  • Yamato oven for drying of samples

    Whole-round measurements:

  • Whole-round multisensor track for magnetic susceptibility, bulk density, P-wave velocity, and non-contact resistivity (Quick Start guide; User guide; Cumulus)
  • Whole-round multisensor track for out-of-sequence “fast” logging
  • Natural gamma radiation multisensor logger with higher sensitivity and faster acquisition rates (Quick Start guide; User guide; Cumulus)
  • TeKa 04 thermal conductivity meter (Quick Start guide; User guide; Cumulus)
