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.


Richard Lewis is the developer of the gas shale evaluation workflow that was initially fielded ten years ago and has been applied to more than 3000 wells in North America. Currently Richard manages a group responsible for the continual improvement for this workflow, for its introduction and application to the international market, and for the development of workflows for the evaluation of liquids-producing shales.

George Waters is responsible for the geomechanical assessment, completion design and evaluation of organic shale reservoirs undergoing exploration and initial development outside of North America. He has designed and evaluated hydraulic fracture treatments on multiple reservoirs in over 20 countries on six continents and has been involved in the stimulation optimisation of organic shales since 2000.
