CCS expertise and analogical reasoning

2023-09-07T20:18:23-06:00

LEE HUNT CARBON ALPHA, LHUNT@CARBONALPHA.COM ERIC STREET CARBON ALPHA GRAHAM HACK CARBON ALPHA We provoke the development of geoscientific expertise for the early stages of CCS through analogy with fields that geoscientists already command. Introduction Recently, there has been a tremendous increase of interest in the safe and permanent underground storage of carbon dioxide (CCS). This has been driven by governmental enactment of climate goals in many parts of the world. These goals have been powerfully manifested in several ways, including through penalties and incentives. Canadian efforts in this regard have included the Government of Canada’s (GOC) rapidly escalating carbon [...]

Lithium Exploration: Successes and Challenges into the 21st Century

2023-06-29T17:04:55-06:00

KATHLEEN DOREY, H.BSC. PETREL ROBERTSON CONSULTING LTD., KDOREY@PETRELROB.COM Introduction While many people think of lithium only in the context of batteries, it is a critical mineral supporting development of diverse new technologies in the 21st century. Global supply chains of years past must be rapidly expanded to meet new demands. Traditionally, lithium has been produced from both hard-rock mines and from highly saline brines brought to the surface and concentrated through evaporation. New mines can be developed, but surface concentration of lithium brines is limited to specific areas and is coming under increased environmental scrutiny. To address the demand, exploration [...]

Geophysics at the University of Alberta: A longstanding and vibrant tradition

2023-05-19T12:31:41-06:00

MIRKO VAN DER BAAN DEPARTMENT OF PHYSICS, UNIVERSITY OF ALBERTA, EDMONTON, ALBERTA, CANADA. MIRKO.VANDERBAAN@UALBERTA.CA Introduction Geophysical research at the University of Alberta has a long and rich history, starting in 1954, investigating both applied and fundamental questions such as: Why do the Earth and planets have magnetic fields? Can we forecast earthquakes? What was the climate like in the past? How did plate tectonics form the Rocky Mountains? How do we locate hydrocarbons and other resources underground? Does hydraulic fracturing cause earthquakes? Is geothermal energy an option for Canada? What happens to CO2 stored underground? The early years: The 1950s [...]

The Relationship between AVO and Petrophysics

2023-05-05T13:18:20-06:00

DAVID GRAY SVP INTEGRATED STUDIES, GEOMODELING TECHNOLOGY CORP, FDAVID.GRAY@GMAIL.COM Purpose The main purpose of this article is to provide geoscientists with one source which uncovers the connection between pre-stack seismic gathers and the petrophysical properties that cause amplitude versus offset (AVO) variations in them. There are many seismic AVO equations in the literature, all parameterized differently, e.g., Shuey (1985), Smith and Gidlow (1987), Verm and Hilterman (1994), and Gray et al (1999). This paper attempts to reconcile these parameterizations by presenting all of these existing equations using common parameters which are defined in Appendix A. Table 1 lists all the [...]

AVO, Seismic Inversion, Machine Learning and Predictive Modelling and the Economics of the Play – New Age for Oil and Gas Exploration

2023-03-30T16:43:21-06:00

BRIAN WM. SCHULTE SPROTT SCHOOL OF BUSINESS – CARLETON UNIVERSITY / SCHIEFER RESERVOIR CONSULTING, BRIAN.SCHULTE@GMAIL488.COM DAVID GRAY GEOMODELING TECHNOLOGY CORP. SENIOR VICE PRESIDENT INTEGRATED SOLUTIONS, DAVID.GRAY@GEOMODELING.COM RENJUN WEN GEOMODELING TECHNOLOGY CORP. CEO, RENJUN.WEN@GEOMODELING.COM   Abstract Proxy modelling using seismic attributes significantly speeds up our understanding of what is going on between wells, adding substantially to the value that geoscience brings to our businesses. One of the most valuable uses of seismic data is to extract fluid and lithological information for reservoir characterization. Amplitude versus Offset (AVO) analysis and seismic inversion (deterministic or stochastic) are valuable tools for doing this. To [...]
