Who Should Attend
Geologists, geochemists, petrophysicists and reservoir engineers who want to understand better their unconventional reservoirs.

Course Objectives
This course will give first-hand experience of the use of XRF and other chemostratigraphy tools and will share methodologies and approaches that maximize the integration of XRF with other disciplines. This course will demonstrate the usefulness of XRF using real case examples and will discuss issues and answer questions that the students may have with respect to XRF and chemostratigraphy tools. 

Course Overview

The course will be a mixture of theory about tools and statistics, real case examples of Canadian shale and tight siltstone reservoirs and group discussions and exercises.

Review of the various chemostratigraphy tools – pros and cons
A comparison of available chemostratigraphy tools essentially XRF, ICP-MS and ICP-OES will help understand what kind of information can be obtained together with the limitations of each of these tools.

Sampling, calibration, resolution, usefulness and application issues
A strong emphasis will be given on sampling strategy as a function of the problem to be resolved or the question to be answered. Limit of detection depends on the nature of the anode of the device as will the range of elements detected.

XRF to complement core descriptions and sedimentological interpretation – evidence and methodology
XRF can be an outstanding tool to complement and quality control core descriptions and interpretations. Group discussion will help the participants grasp how to make maximum use of XRF elemental values, trends or outliers to review and complement existing interpretations.

Acquisition and use of XRF from drill cuttings and from outcrops 
Some precaution may be needed when dealing with XRF measurements of drill cuttings, uncut cores or from outcrops. For example results will vary when selecting different cuttings size as finer cuttings will take less time to reach the shale shaker. Use of XRF vacuum pump will not be possible on cuttings or in most outcrop situations.

Use of single elements, ratios for various geological and engineering proxies
The XRF analysis provides many measurements of many elements. A review will be made to select the best suited approach as a function of the objective of the study.

Review of methods to optimize, speed-up and quality control correlation
Numerous analytical and graphical methods will be demonstrated with real shale and tight siltstone case examples

Image analysis and shades of grey profiles as a complement to XRF
The usefulness of shades of grey profiling will be demonstrated together with examples of what not to do. The main focus being its integration with XRF data and with sedimentological descriptions. Assessment of Total Organic Carbon or presence of bitumen will be explained with examples from the WCSB.

Tested and newly developed statistical approaches for multivariate and PCA analyses
Typical statistical tools will be described, some being more analytical and other ones being more graphical. Additionally some new PCA approaches tightly tailored for the oil industry and more particularly for XRF have delivered very promising results that will be demonstrated during the course.


Jean-Yves Chatellier is a geologist with 35 years of international experience, the last 10 years being dedicated to shale and tight sands. He specializes in multidisciplinary integration from geosciences to engineering. He graduated in geology from Lille, received an MSc in sedimentology from Calgary and MSc and PhD in structural geology from Paris. He worked around the world for Shell before taking a senior advisor job for the research lab of PDVSA in Venezuela. After seven rewarding years, and the discovery of two giant oil fields he left the country during the national strike to settle down in Calgary. At Talisman he worked on new play concepts and was at the beginning of the shale exploration and development in the Utica, Montney and Duvernay. He is now consulting on various shale and basin analysis for several oil companies. He is the current chair of the AAPG Research Committee and has been the convener of three major conferences and three Hedberg Research Conferences.
