Abstract: Advances in the Realm of Hydrogeophysics: The Emerging Role of Quantum Geoelectrophysics in Aquifer Exploration

Water is integral to our economy, the health of our environment, and a necessity for all life forms and human development. Most water is accessed from surface sources, primarily rivers, which are now under increased threat due to over use and growing hydro-political forces. Still, groundwater exists as a viable option in many countries facing these mounting challenges.

Abstract: Extending the reach of radio waves for subsurface water detection

Shallow and deep groundwater can be a major environmental obstacle for any geophysical surveying technique, especially radio waves. Ground penetrating radar (GPR) is a mature technology with applications in many areas; see Daniels (2004) for an overview. Almost all applications are restricted to imaging the subsurface to a rather shallow depth: large losses of signal occur when propagating through materials with free ions.

Abstract: A cost effective approach to regional and site-specific aquifer exploration using combined airborne and ground electromagnetics

Shallow groundwater is often hosted in Quaternary sediments that are very complex in nature and challenging to map. Traditional mapping and exploration methods to delineate these features are often time consuming, costly, and provide uncertain results. Airborne electromagnetic (EM) techniques have proven effective in delineating these aquifers over extensive geographic areas in a very timely and cost effective manner.

Abstract: Emergency Response Groundwater Exploration at Rohingya Refugee Camps in Bangladesh

As geoscientists and engineers, and like most other professionals, we take pride in using our education and experience for the betterment of society. In developed countries, the value of such work on water supply projects may not be so obvious, where we take for granted that our communities will always have access to a ready supply of safe drinking water, and that we have built enough resilience to avoid running out of water should catastrophe strike.

Quantitative comparison of inversion methods for estimating density from seismic data: multi-component data improved seismic prediction

In the Athabasca oil sands, lithology and fluid composition are typically better correlated with density than with other elastic properties, such as P- and S-wave velocity. Therefore, improving the accuracy of density estimates in oil-sands reservoirs has become one of the most important goals in quantitative interpretation.

Applications of DC Resistivity and Magnetotelluric Methods in Exploration

The Schlumberger brothers were the first to use the direct current (DC) resistivity method for exploration, in oil well boreholes in Russia during the 1920’s. A unique phenomenon, now referred to as induced polarization (IP) chargeability, was noticed at the time, but not understood until simultaneous developments in both Russia and North America in the 1950’s. This lead to the development of the time domain and frequency domain IP methods.

Abstract: Muon Geotomography: A Novel, Field-Proven 3D Density Imaging Technique for Mineral Exploration and Resource Monitoring

Muon geotomography is a novel density measurement technique based on the absorption of cosmic ray muons in the ground. Naturally occurring cosmic ray muons emanating from the upper atmosphere lose energy as they penetrate the earth. These muons are absorbed at a rate that is proportional to the density of the material they pass through.

Abstract: Seismic Acquisition Innovations Applied in Canada

Over the past 10 years, land seismic acquisition has changed significantly. Nodal/cable-less systems have broadly replaced cabled systems, vibroseis sources have replaced explosive sources even in areas with difficult terrain, and high-density seismic programs are becoming commonplace.

GeoConvention 2018 Report
GeoConvention 2018 Report

On the heels of a very successful GeoConvention 2018, we would like to thank all of the individuals who attended and the companies who supported the convention by exhibiting, sponsoring and supporting their employees’ attendance. GeoConvention 2018 saw increased attendance, a larger number of exhibitors and greater sponsorship than in 2017.

CSEG Foundation Mentorship program

The CSEG Foundation Mentorship program, just completed its 9th year, and it was a year of challenge, change and progress. 2017/2018 saw membership in the program drop steeply from over 50 pairings in previous years to 33 pairings this year. Although it was smaller, the Mentorship program continued to strengthen its national and international reach with ten ‘distance’ pairings.

Abstract: From X-ray Fluorescence (XRF) to mechanical profiling for better well completion. Valuable analytics for the exploration toolbox!

.The fast pace of drilling and completion of unconventional reservoirs in North America is challenging engineers, geoscientists and petrophysicists who have to make prompt and reasonable plans for drilling completion strategies. One of the main issues is understanding the physical rock properties, such as clay and organic content, and mechanical properties or stress behaviour, in these often highly anisotropic reservoirs.
