CARBONATE REVIEW, POROSITY CLASSIFICATIONS AND
SAMPLE EXAMINATION TECHNIQUES
Second Floor Training Room, Continental Laboratories,
3601A – 21 Street N.E., Calgary, Alberta
2-day workshop
October 27 - 28, 2015
Instructor: Peter Hews, Hara Consulting Ltd.
08:30am to 4:15 pm
The workshop is presented by a geologist with over thirty five years experience in western Canada, as well
as Europe, South America and the Caribbean.
The purpose of this two-day workshop is to provide a practical, hands-on review of some of the fundamental
aspects of carbonate geology as well as an overview of some of the classification techniques employed in
the western Canadian subsurface. Cuttings sample examination of carbonates requires some additional skill
sets generally not employed when looking at and describing detrital / clastic rocks. The second day of the
workshop will provide participants with those skills - practical, hands-on techniques to fully examine and
describe carbonate drillcuttings. The workshop is supplemented with digital images to explain fabrics,
textures and techniques employed in the western Canadian subsurface.
