Organic Shale Evaluation and Completion

Reservoir Description and Dynamics Drilling and Completions


This course introduces us to the evaluation and completion techniques utilised on organic shales. Geologic settings for optimal organic shale formation are reviewed. Petrophysical analyses of both gas bearing and liquid bearing organic shales via logs and core are presented. Means of assessing key geomechanical parameters are introduced as well as how these measurements are used to design stimulation treatments. The course will also cover efficient completion practices that are regularly employed to ensure efficient, cost effective development.

Who Should Attend

Geologists, geophysics, reservoir, production and stimulation engineers and exploration managers.


Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and or/ certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDH). Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course.


Brian Clark is a Senior Production and Completions Engineer in the Schlumberger Unconventional Resources Group in Houston, Texas. He joined Dowell Schlumberger in 1994 and has held numerous completion engineering assignments starting in 1998, focusing primarily on low permeability hydraulic fracturing optimization. He is currently involved with the geomechanical evaluation of organic shale reservoirs under exploration outside of North America. He holds a BS in Mechanical Engineering from Clarkson University.

Erik Rylander is a Senior Log Analyst for the Unconventional Resources Group of Oilfield Services located in Dallas, TX. Rylander is part of a group responsible for the continual improvement of shale analysis workflows, and for its introduction and application to the international market.  Rylander's current focus is the application of nuclear magnetic resonance and geochemical logs to liquid bearing shale reservoirs.  He has been with Schlumberger for 19 years and began as a wireline field engineer in W. Africa and the Gulf of Mexico.  After an operations management position, Rylander entered into a product champion role at Schlumberger’s product center in Clamart, France where he focused on the application of dielectric logs. Nine years ago, he began focusing on the petrophysical analysis of shale reservoirs in Dallas, Texas.
