Chief Geophysicists Forum

The Chief Geophysicists Forum is comprised not only of Chief Geophysicists, but also of managers involved in a geophysical technical role and senior level geophysicists that are willing to accept additional responsibilities. We get together once a quarter for a breakfast meeting to hear the latest CSEG, APEGGA and CAPP news and to tackle technical issues that benefit our industry community here in Calgary and beyond. The CGF is a Standing Committee of the CSEG.

The value added role of Geophysics in the Canadian Oil and Gas Industry

The role of geophysics in the industry is a robustly debated subject these days. As our industry continues to evolve in order to meet challenges brought on by unconventional resources, changing supply and demand factors, environmental drivers, and legislative and tax regime changes – just to name a few – all aspects of our industry are under scrutiny. Nobody wants to spend money or do anything that cannot be immediately assessed for the value it adds. It is under this scrutiny that geophysicists could perhaps be forgiven for periodic existential anxiety.

Guidelines for Standard Deliverables from Microseismic Monitoring of Hydraulic Fracturing

The Microseismic sub-committee of the Chief Geophysicists' Forum (CGF) has produced a draft document titled 'Guidelines for Standard Deliverables from Microseismic Monitoring of Hydraulic Fracturing'. The purpose of the document, which is authored by Shawn Maxwell and Florence Reynolds, is to describe suggested guidelines and minimum requirements for standardized microseismic deliverables . It is hoped that standardization will facilitate proper archiving of both data and reports, enable opportunities for efficient and effective reprocessing, and support industry exchange and trading of data.

The document has now been reviewed and commented on by both the CGF and CSEG membership and at the end of 2012, it was endorsed by the CSEG executive. Should you wish to provide any further feedback, please contact Shawn Maxwell at

CGF Reserves document on Geophysical Applications – Using Geophysics for Reserves and Resources Classification and Assessment

The CGF Reserves document has been approved by the CGF and the CSEG Executives and has been forwarded to the SPEE for a COGEH update. The document as written by the CGF sub-committee and is provided on this webpage for your reference. It is a modification of the Society of Exploration Geophysicists Oil and Gas Reserves Committee (SEG OGRC) recommendation to the Society of Petroleum Engineers (SPE) for an update on Chapter 3 of the applications publication for the Petroleum Resource Management System Application Document (PRMS AD). Further modifications were made by the Canadian Society of Exploration Geophysicists (CSEG) Chief Geophysical Forum (CGF) Reserves sub-committee.

This initiative was undertaken by a sub-group of the CGF under its mandate "to tackle technical issues that benefit our industry community here in Calgary and beyond" (CSEG Recorder September 2010); driven as well by industry focus on 'new' reserve/resource booking processes resulting from changes to guidelines from several bodies including the SEC and COGEH.
