Introduction to April Focus: Data & Data Management

Brian Schulte

Welcome to the printed GeoConvention edition of the RECORDER. The focus is “Data and Data Management”. It is amazing how many articles were gathered by Special Coordinator Trudy Curtis and Technical Editor Kristy Manchul. Trudy and Kristy began gathering material for this back in October. As with all our editions,…

New Canadian Well Identifier System

Floy Baird and Sue Carr

It’s 1965, and a new standard is being rolled out in the Canadian petroleum industry. Designed by industry, for industry and adopted as a standard by the Canadian Petroleum Association (CPA), it became known as the CPA UWI (unique well identifier). In 1965, Lester B. Pearson is the Prime Minister…

Google Your Way to Maximimum Geoscientific Value

Marc J. Boulet

Although there is an exponential increase in data collection within oil and gas companies, access to the data for meaningful subsurface interpretation is constrained by the limited toolkits many geoscientists have at their disposal. We propose some methodologies and open-source software tools that can provide more efficient access to structured…

E&P Companies, Different Types of Data, Fairway Mapping and Geomodels

Brian Wm. Schulte

E&P companies are looking at data differently than they did in the past. The reason why they are doing this is because data drives big economical decisions, including the sanctioning of a new play, which is when the Board decides to spend a large amount of money on the development…

Geophysical Data Compliancy – Utilizing Technology

Sue Carr and Trish Mulder

Geophysical data compliancy means only using data you are entitled to use for an implicitly defined purpose and timeframe. Geophysical / seismic data is complex, as it is an image of a defined position on the earth. That representation is multi-dimensional, multi-faceted and geographically based consisting of raw and interpretation…

The Future of Data and Data Management Trudy Curtis

Trudy Curtis

Attenuation refers to the degradation of signal strength as it decays over time, across distance, or through interference. Working out what causes attenuation takes lots of time and patience. But it’s worth the effort to solve the problem, because doing so strengthens customer trust and loyalty.

Ocean Bottom Seismometer Instrumentation in Canada

Mladen R. Nedimović

Canada belongs to an elite club of a handful of countries that successfully developed and used autonomous ocean-bottom seismometers (OBSs). Yet, with the decommissioning of the Canadian short period OBS pool in 2015 due to old age and retirement of researchers with OBS knowledge, Canada was on the verge of…

Atlantic Rifted Margin Studies from the Edge: Geophysical Research at Memorial University

J. Kim Welford, Alison E. Malcolm, Colin G. Farquharson, and Jeremy Hall

Located in Canada’s easternmost province of Newfoundland and Labrador, researchers at Memorial University are ideally positioned to undertake geophysical research along the country’s Atlantic margins where offshore exploration is still very much at the frontier stage, spurred on by world-class discoveries and production in the Jeanne d’Arc and surrounding basins.…

Exploration Initiatives, Offshore Regions, Newfoundland and Labrador, Canada

Deric E.L. Cameron, Erin Gillis, Victoria Mitchell, and Richard Wright

Exploration initiatives over the past decade have led to renewed interest in exploration in the slope and deep-water regions of offshore Newfoundland and Labrador, Canada. New multi-client regional 2D seismic surveys (2011-2018), guided initially by satellite slick mapping, have provided approximately 170,000 line kms of long offset, broadband 2D seismic…

Frontier Exploration: Considerations When Developing a Predictive Rock Physics Framework

Nick Huntbatch, Alsing Selnes, Neil Whitfield

Exploration in frontier basins is challenging; subtle targets, large seismic datasets, sparse well penetrations, and many unknowns. There is an obvious requirement for interpretations to be robust, but also delivered on a commercial timeframe.

Building a Geological-Pressure Model Incorporating Global Analogues

Sam Green and Alexander Edwards

To de-risk a frontier area properly requires establishing the geological framework, and this is where seismic data can provide important controls on the basin framework by helping to understand features such as stratigraphic thicknesses, large-scale structural features such as faults and folds, and vertical and lateral velocity variations. To help…

Repositioning Seismic Technologies and Services in a Dynamic Upstream Oil and Gas Industry

CAGC Executive

In September of 2018 the upcoming winter season quickly went from decent to dreadful. With the widening of the Oil Differentials, potential projects were cancelled and the outlook for 2019 began to look like the bottom experienced back in 2016. The CAGC commissioned the following op-ed in order to look…

An Unconventional View of Geoscience

David Gray

hale oil and gas production and “fracking” are with us to stay. We geoscientists need to understand how we can contribute to the “shale revolution.”

Skeletonization and Empirical-Mode Decomposition of 2-D Potential-field Images

Le Gao and Igor B. Morozov

The volumes of modern gridded data collected by the geophysical exploration industry are often large and can benefit from methods for image decomposition, pattern analysis, and interpretation. Automated pattern-recognition methods can be useful for both seismic and potential-field images. In both of these cases, it is important to extract quantitative…

Mechanics of Seismic Q

Igor B. Morozov

Seismic- wave attenuation and dispersion are studied in most geophysical curricular and broadly used in both academic and applied research. Applications of these concepts include identification of gas reservoirs and chimneys from frequencydependent seismic amplitudes, analysis of frequency dependent P- and S-wave velocities, interpretation of the effects of porosity and…

CCArray and EON-ROSE: Emerging Pan-Canadian Multidisciplinary Research Initiatives

David W. Eaton, Katherine Boggs, Thomas S. James, Jason C. Droboth, Pascal Audet

The Canadian Cordillera – the mountainous regions of western Canada – represents a world-class natural laboratory for exploring the interconnected Earth systems that are critical to our understanding of major scientific grand challenges. The Canadian Cordillera Array (CCArray) is a proposed international scientific initiative, spearheaded by the creation of a…

Impact Craters in Seismic Data

Amanda Obodovsky

Since the acquisition of seismic data in the 1960’s, impact structures have been seen in seismic data. These are structures that were created earlier in the Earth’s history from a meteorite impact and have since been buried underground. While many of these unique structures are known to be located in…
