Introduction to Petrophysics

Petrophysics is fundamental to all aspects of the petroleum business. Principles, applications, and integration of petrophysical information for reservoir description will be discussed in depth. Through a combination of class discussion and exercises/ workshops, participants will learn how to conduct competent quick-look evaluations. Using data from open hole logs, logging-while-drilling, and core data you will evaluate porosity, permeability, and saturation in a variety of reservoirs. Knowing how to integrate petrophysical information with other data sources will improve participants’ ability to assess technical risk when examining hydrocarbon opportunities.

Upon completion of this course you will be able to know how to:

  • Understand and apply at a basic level the theory and operation of major petrophysical tools
  • Calibrate porosity and permeability values from core and log sources for improved saturation calculations
  • Apply basic cased-hole logging, borehole seismic, image, and LWD/MWD
  • Analyze and integrate log, core, geosciences, and engineering well data for well and field development projects
  • Select petrophysical tool combinations for specific applications
  • Assess the impact of petrophysical analyses on technical uncertainty estimates of reservoirs
