Compensating Missing Source Points: Minimizing loss of coverage in 3D seismic surveys for areas where sources cannot be deployed, yet geophones may be planted

Gijs J.O. Vermeer

In 3D seismic acquisition it may happen that in some areas sources are not allowed whereas geophone planting is permitted. Examples of such areas are nature reserves, parks, lakes, and other sensitive areas. Often, it might be possible to circumvent the problem by using weaker sources or using buried sources…

Magnetotellurics in Exploration for Geothermal Targets

José Antonio Rodríguez, Mehran Gharibi, Oliver Kuhn

The increasing demand to develop renewable energy resources has driven a surge in interest in geothermal sources, both for power generation and for direct use of heat, or for a combination of both.

Risk-Based Design of Site Characterization and Measurement, Monitoring, and Verification Plans for Carbon Capture, Utilization, and Storage Projects

Marcia L. Couëslan, Wade Zaluski, and Brody Loster

Renewed interest in carbon capture, utilization, and storage (CCUS) has exploded in the last 12 to 18 months in both the United States and Canada. This has been precipitated by the 45Q Carbon Capture Tax Credit in the United States and the federal carbon tax and Clean Fuel Standard in…

Evidence for Strike-Slip Faulting from 3D Seismic and HZ Well Strip Logs and its Impact on Hydrocarbon Distribution at the Worsley Charlie Lake LL Pool

Rainer Augsten

Faults have always played a major role in the trapping of hydrocarbons, usually by creating structural traps. Faults with associated vertical displacement or folding are often visible on seismic data. Strike-slip faults with no vertical displacement, on the other hand, are notoriously difficult to detect on seismic data. This article…

Integrating Pore Pressure and Lithology Prediction from Well and Seismic Data to Characterize Abnormal Pressures in the Compartmentalized Volve Oil Field, Central North Sea

Draga Talinga and Carl Reine

Pore-pressure distribution within the clastic and carbonate Mesozoic sequences at the Volve oil field in the Central North Sea is particularly interesting due to the presence of two distinctive pressure regimes within the Jurassic sandstones: one hydrostatic and one moderately overpressured.

Effective Technical Talks

Stewart Trickett

Being an expert in your field is not enough. You must communicate your knowledge and findings effectively. Although natural aptitude varies, communication skills can be studied, practiced, and refined like any other. You need only apply yourself.

The Prevention and Cure for Tube Waves

Allan Campbell

In recent years, vertical seismic profiling (VSP) has become an important tool for geophysicists involved in the exploration for oil and gas. VSP’s can provide precise time-depth relationships for seismic reflections. VSP’s frequently have better resolution (wider frequency bandwidth) than surface seismic. Unlike most surface seismic, the VSP corridor stack…

Useful Mistakes, Cognitive Biases and Seismic

Lee Hunt

We come to conventions and Symposia to hear about success and bask in the glory of our awesome, successful colleagues. But mistakes may also lead to useful learning opportunities. After all, we often mistakenly look upon our successes as if they are the result of some intrinsic property of ourselves,…

Depth Imaging – Above and Beyond Reflections: The Why and How of Your Pre-stack Depth Migration Project

Svetlana Bidikhova and Mike Hall

When I was a student, I learned the magical, melodic word “migration” but not in relation to butterflies, birds or wildebeests. Since then, I have dedicated several years of my post-graduate research work to migration, only to understand the brilliance of the Socratic Paradox that, "I know that I know…

Focus Introduction: Potential Careers in Sustainability and Renewables

Keith Hirsche and Joan Embleton

There are many who do not believe renewables will provide solutions to our energy needs. Some feel that the Paris Accord is based upon a fundamental misconception of climate history and science and the push to meet its requirements are mistaken. They feel strongly by moving towards renewables, electrification (electric…

Geophysics for an Energy Transition

Kathleen Dorey

As the world is slowly transitioning to non-traditional forms of energy use and consumption there are a number of energy related projects that still require high level geophysical applications in Canada and around the world. In the last few years projects outside the traditional oil and gas space have still…

Geothermal Energy – A Sustainable Alternative to Well Abandonment

Jeremy Boak, Alan J Cohen, Salah Faroughi, Hamed Soroush and Maria Richards

Geothermal energy has the potential to supply more energy than the global total of oil and natural gas combined. It is renewable, stable, and has a minimal carbon footprint. Geothermal power plants can produce electricity consistently, constantly, and without regard to weather conditions.

Transitioning from Mining to Solar

Adam Yereniuk

When I left the mining industry in 2015 to start a business in the solar energy industry, I knew little about solar or business. It was a very scary shift, but in my heart, it felt like the right move for my long-term career. What I lacked in knowledge; I…
