Estimating Permeability and Porosity From Drill Cuttings Workshops – Fall 2014

The workshop is suitable for persons with some experience and comfort level with drill cuttings. We recommend that participants have taken the Canstrat course or have at least 1 year of wellsite or Petrographic lab experience before taking it. Most of the time in the course is spent examining rock samples through a stereomicroscope. Participants will need to bring a microscope that goes up to at least 40X. Loaner microscopes are available for an addition fee of $25. The course time is divided approximately 20% lecture/discussion and 80% microscope time. Lunch is provided on both days.   


  • Estimation of total porosity, including micro porosity, by visual, microscopic examination.
  • Review of Archie carbonate classification system.
  • Permeability estimation methods through visual examination Instruction of permeability classification systems (Sneider, Lucia)
  • Hands-on exercises to practice techniques.

The approach we use involves the calibration of drill cuttings porosity and perm estimates to core pieces with reliable analysis; examining both clastic and carbonate reservoirs. A comprehensive manual is supplied to each participant, which outlines techniques and procedures for drill cutting evaluation for future reference.
