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…

Sayer’s Outlook for 2017 Oil & Natural Gas Mergers & Acquisitions Activity

Alan W. Tambosso

In spite of prolonged low commodity prices, 2016 turned out to be an average year for mergers and acquisitions activity (“M&A”) in the Canadian oil patch. While the nature of transactions may change somewhat, with the worst of the price onslaught apparently behind us, 2017 could end up being a…

APEGA Legislative Review: Summary of Consultations

Neda Boroumand, Rachel Newrick and Ken Mitchell

The APEGA Legislative review was an initiative that began in 2015 and was prompted by the Government of Alberta (GOA) in 2014. The objective of the review was to update the Engineering and Geoscience Professions Act (EGP Act) and General Regulation to reflect today’s industry practice and ensure that the…

Introduction To March Focus: Back to Basics

Nicole Willson

The idea for this FOCUS came from a member who replied to one of the CSEG’s member surveys concerning the RECORDER. So, thanks to that member who let us know, and who gave us the great title “Back to Basics.” Many other members also asked for technical content that was…

Datums, Projections and Coordinate Systems

Adam Thomas

Accurately describing locations on Earth is essential to exploration geophysics. The interpretation of fault zones, the surface and bottom locations of a well, and the position and orientation of seismic ground control points and receivers are all dependent on being able to accurately describe where they are. Unfortunately the latitude…

Discovering A Supermodel – A Rock-Physics Tutorial

Carl Reine

Quantitative interpretation (QI) involves making predictions of rock and fluid properties from seismic amplitudes. Within the QI workflow, a number of components can greatly benefit from rock physics, which itself is an incredibly diverse field. Rock physics covers the measurement of rock properties in the lab, the empirical and theoretical…

Knowledge True and False: Scientific Logic and Climate Change

Henry Lyatsky

This scientific “truth” was drilled into me, a young geology undergrad in Calgary, by esteemed professors in basic courses at the beginning of the 1980s. In the 1970s the media were abuzz with global-cooling scares. Cooling was supposedly a scientific fact. Thankfully, the old fears of an impending new ice…

Two Workflows for Image-Based Near-Surface Modeling for Statics Corrections and for Circumventing Velocity Uncertainty in Subsurface Imaging of Complex Structures

Öz Yilmaz

In exploration seismology, the most common type of the near-surface is defined as the depth interval below the topography, composed of a low-velocity, unconsolidated, heterogeneous soil column and weathered rock layer. As such, raypaths are close to vertical incidence within the near-surface – a requirement for statics corrections to be…

Introduction To January Focus: Geostatistics. Big Data. Analytics.

Neda Boroumand

The branch of statistics, “Geostatistics”, the term “Big Data” and the scientific process of “Analytics” have been around for a while. However, their application on data acquired for subsurface evaluation and resource development is becoming increasingly important. The present day Geophysicist/ Geoscientist is having to make sense of more and…

Incorporating Big Data in Geostatistical Modeling for Making Bigger Decisions in the Face of Even Bigger Uncertainty

Jeff B. Boisvert and Clayton V. Deutsch

The main purpose of generating geostatistical models of reservoir properties is to use them to calculate quantities of hydrocarbons or make decisions on how/if to produce the resource. In today’s data rich environment there is increasing data available for building these models; however, it is often difficult to convert this…

Data Analysis of Induced Seismicity in Western Canada

Hoda Rashedi and Alireza Babaie Mahani

Due to the recent increase in the rate of seismicity in western Canada and central eastern US from oil and gas activities, there is a high demand for data from seismographic networks to understand ground motion variability and assessment of seismic hazard to the critical infrastructure. In western Canada, efforts…
