Part of CWLS’s mission is education and the value of thorough competent integrated Petrophysical evaluation. We are excited to announce that we have partnered with Ross Crain to showcase a series of on-demand lectures and presentations. The goal is to educate management, shareholders, geoscientists, engineers, and students across the Oil and Gas industry on the value and power of Petrophysics and formation evaluation. The CWLS is very grateful and thanks Ross Crain for his continued support of the society and dedication to continuing education and the discipline of petrophysics.

This will be a feature offered to members and members of our affiliate societies; SPWLA, CSPG, CSEG. (please contact your society and to attain access)

To further achieve this mission, the CWLS website would like to offer additional on-demand video presentations and courses from interested service companies, oil/gas companies, and consultants. Please contact us at to share your content and insight and add value to our technical communities.
