Together, we are facing a truly unprecedented situation. The global coronavirus pandemic is affecting all of our families, business, communities, and way of life.  To that end, details will be posted on events as the situation progresses.



DATE:  Wednesday, November 4, 2020

TIME: 11:00 am – 12:00 pm

TOPIC:   Extracting Value at Logging Measurements using a Probabilistic Petrophysical Model – A Duvernay Case Study

PRESENTER: Oscar Perez Michi

Abstract:  During this presentation, you will see the integration, analysis, and interpretation of petrophysical information aiming to characterize the Duvernay reservoir properties in the Kaybobs Area. This petrophysical workflow, which includes more than 50 wells, can be applied at other unconventional reservoir plays, expand the area of analysis adding more wells, transfer the results at other domains such as geology and geomechanics in order to improve the interpretation time, regulate the minimum set of data requested and evaluate reservoir performance. 

Speaker Bio:  Oscar Perez Michi is a Petroleum Engineer with 24 years of international experience in reservoir characterization of the oil and gas industry. Skilled in logging acquisition, formation evaluation, acoustic-geomechanics, pressure transient analysis and production logs. He has worked as Technical Software Support Engineer, Reservoir Domain Champion, Log Analyst, Data Services Manager, and Consulting Petrophysicist.  His skill set includes providing on-site support, teaching petrophysical courses, giving real time solutions, and assisting in consulting projects.  In his previous job, he was the focal point for unconventional petrophysical-reservoir analysis for O&G companies based in Calgary.

CWLS is committed to engage our members with strong technical and professional development by providing technical luncheons, publications, educational resources and courses.

The CWLS is actively working to collaborate with other professional associations across our industries to help facilitate the exchange of knowledge, expertise and best practices locally and internationally. 

Upcoming CSPG Events:

        Gussow Conference 2021  March 10-11, 2021  Earl Grey Golf Course, Calgary, Alberta 


The Canadian Well Logging Society (CWLS) announces yearly awards for engineering and earth sciences undergraduate and graduate students in Canada. The purpose of these awards is to raise interest and awareness of careers in Petrophysics and Formation Evaluation. Formation Evaluation and Petrophysics are the studies of rocks and their fluid properties as they pertain to the oil and gas industry.

This year, the Winston Karel CWLS Student Award will be funded by Lois Decker, wife of Winston Karel. Winston Karel was a long time CWLS member and friend to the community who passed away on July 1st, 2015.

Best Student Thesis wins $1000
Best Student Abstract wins $500

Submissions should critically examine some aspects of well logging, formation evaluation or petrophysics and should be submitted to the CWLS in their final year of study. The final thesis can be submitted at any time in the year of graduation. Submission deadline is October 31, 2020 and the CWLS will select award winners by mid-November of this year.

The winners will be invited to the December luncheon or AGM to receive the awards and to make a presentation at a CWLS lunch meeting in Calgary later in the year.

Student Award Eligibility Criteria: Candidates must be registered full-time at a Canadian university. A student’s financial need will be considered.

Student Award Application Procedure:  Completed application forms must be received before October 31, 2020. Application forms can be downloaded here:  Award Application

Please submit application forms by email to:                       Applications may also be submitted by mail to:
