Improving Seismic Data Quality by Reprocessing and Redesign of a 3D Survey in an Area of Chaotically-scattered Source-generated Noise

Norman Cooper, Yajaira Herrera-Cooper, Eduardo Trinchero, Luis Vernengo, Raúl Stolarza

The purpose of this paper is to propose a two-fold solution to a complex noise problem in the Gulf of San Jorge Basin in Argentina. Irregularly shaped intrusive bodies scattered at shallow depths over large areas above the reservoir generate a severe signalto- noise problem that masks deeper reflection signals…

How Geoscientists are Making Potash Mines Safer

Craig Funk, Janelle Appleyard, Jennifer Braun, Jodi Derkach

Within the vicinity of Saskatoon, Saskatchewan, potash is conventionally mined by three operating companies at five different mines. Continuous boring machines (borers) cut the potash out of the seams at about one kilometer depth. The stratigraphy of the roof above the mined-out rooms (salt-beam) in the Saskatoon area mines consists of…

Case Study of Mineral Deposits in the Yukon Using High Resolution Resistivity Induced Polarization Techniques

Melvyn E. Best and Isaac Fage

During 2013 and early 2014 a test program was carried out to evaluate a multi-electrode, High Resolution Resistivity/ Induced Polarization (HRRIP) system over 9 mineral deposits within the non-glaciated region of the Yukon. The HRRIP system was chosen over conventional resistivity/IP systems used in the mining industry for the following…

Data Interpretation and Integration from a Seismic Perspective – The Excitement of Innovation

Laurie Weston Bellman

It’s a little cliché to say, but technology is changing so fast that it’s difficult to keep up. Computer storage, processing speeds and visualization capabilities continue to grow exponentially; “integration” (however difficult it is to define) is the dream of most geoscience departments and generic “big data” analysis techniques are…

Techno-economic Assessment of Solar Technologies in Canadian Housing Stock

Sara Nikoofard

Being one of the least densely populated countries in the world, Canada’s rigorous climate, the energy intensive nature of the country’s industries, and the large distances between population centers result in a relatively high per capita energy consumption. In 2013, for example, Canadians consumed 7.2 tonnes of oil equivalent per…

Scanning Calgary’s ‘Water Towers’: Applications of Hydrogeophysics in Challenging Mountain Terrain

Craig W. Christensen, Masaki Hayashi, Laurence R. Bentley

Among hydrologists, mountains are popularly referred to as the “water towers of the world.” Though only covering approximately 25% of the world’s land surface, they account for anywhere between 32% (Meybeck et al. 2001) and 60% (Bandyopadhyay et al. 1997) of water flow in all rivers. Moreover, a disproportionate number…
