1. Practical QI

Presented by Laurie Weston

Course Dates:

2 Full Days – 8:00 AM – 4:00PM MST

Tuesday, November 7th, 2023

Wednesday, November 8th, 2023

Location: TBD

Course Level: Fundamentals

Target audience: Seismic interpreters (geophysicists and geologists)

Special Requirements: Sound QI software will be provided on workstations (if available) or student laptops.

This course will encompass all elements of quantitative seismic interpretation, including assessing key data inputs (such as well information and pre-stack seismic data), covering key aspects of AVO, inversion and mathematical attributes, how machine learning provides ‘smart’ attributes, and, most importantly, how to combine all the elements into a coherent interpretation of geology. Participants will gain an understanding of why, how, when, and to what extent QI should be used to add value in an exploration or development environment for any subsurface imaging objective.

Topics covered include log and seismic data inputs and conditioning, rock physics modeling, AVO, inversion (all types), rock type classification, and, if time permits, an overview of advanced topics such as multicomponent data, time-lapse data, microseismic, and VSP’s, all in the context of contributing to an effective QI workflow.

Laurie Weston is the President and CEO of Sound QI Solutions Ltd., a Calgary-based QI consulting and software company she founded in 2007. Originally a physics/astronomy graduate from the University of Victoria, B. C., Canada, Laurie started her oil and gas career with Shell Canada doing seismic processing and interpretation in the central plains area of Alberta. Seeking adventure and travel, she took a position with LASMO plc in London, to work on various European, North African, and Middle East exploration projects. She later returned to Canada and began her consulting career, initially with short term interpretation contracts for a variety of companies. As her interest in the early days of QI grew, she started her own company to explore and contribute to this fascinating field.

Since then, Laurie has been ‘practicing’ QI for over 15 years – the latter half of her career as a geophysicist in the oil and gas business. Through her interpretation experience in many basins around the world, she is well aware of the combination of hard data, imagination, creativity, and collaboration that is necessary to be an effective and successful member of an exploration or development team, regardless of background. Laurie’s education in physics and astronomy, and her early career as a seismic processor have given her a respect (and healthy skepticism) of data and data analysis. The integration of all these aspects is her objective in the application of QI workflows.

Laurie has received numerous awards and honors for her work and presentations, including being selected as the 2017 CSEG Distinguished Lecturer. She has presented this course multiple times for the CSEG Doodletrain.

Laurie is an SEG, EAGE, and AAPG member, and an honorary lifetime member of the CSEG.

2. CANCELLED – Seismic Survey Field Operations: Data Quality, Efficiency, Cost-effectiveness, and Lowering Environmental Impact

Presented by Andrea Crook, Mostafa Naghizadeh, Michael Hons, David Simmons

Course Dates:

2 Full Days – 8:00 AM – 4:00PM MST

Monday, October 23rd, 2023

Tuesday, October 24th, 2023

Location: TBD

Course Level: Fundamentals

Target audience: Anyone interested in what actually happens between selecting geometry parameters and raw field data being delivered to a processor: geophysicists, geologists, engineers, technologists, managers, procurement personnel, students, etc. No knowledge of seismic acquisition or geophysics is required.

Special Requirements: Please bring a laptop or ensure they have a calculator to complete simple comparisons. If students are interested, OptiSeis will provide software and a demo project to help visualize field operations and equipment movement, but this is not necessary for completing course work.

This course will begin with the assumption that seismic acquisition geometry parameters have been selected and will cover what happens from this point onward until the data arrives at the processor. This includes preparation for government approvals, permitting, sending out bid requests, bid reviews including bid normalization, selecting acquisition contractors, contractor readiness, and field operations. The field operations will cover various types of seismic acquisition programs (e.g., explosive vs. Vibroseis, cabled vs. nodal, etc.) and will review important considerations when operating in different terrains (open farmland vs. forested, when heli-portable operations are required, etc.). Each aspect of field operations will be highlighted starting with front end (exclusion mapping, line clearing, surveying, and drilling) followed by recording (layout of equipment, efficiently moving equipment through the field, harvesting data). Additional topics will include considerations for acquiring high density Vibroseis programs and reducing the environmental impact of seismic acquisition. Participants will leave with a good understanding of program timelines, the amount and type of work involved, what input data is required for successful completion, and what output datasets are generated and should be archived.

Andrea is the co-founder & CEO of OptiSeis Solutions Ltd., where she leads a team focused on innovation and operational excellence, and has helped develop EcoSeis, a method for achieving a 50% land footprint reduction while safely acquiring high-quality subsurface data.

3. Carbon Capture and Storage with Carbon Management Canada Facility Visit

Presented by Marie Macquet, Don Lawton, Brendan Kolkman-Quinn, Hamid Behmanesh and CMC Team Members

Course Dates:

1 Full Day and 1 Full Day Field Trip

Wednesday, October 18th, 2023 –8:00 AM – 4:00 PM MST

Thursday, October 19th, 2023– 8:00 AM – 4:00 PM MST (approx.)

Location: TBD

Course Level: Fundamentals

Target audience: This course is directed to Geoscientists and Engineers who would like to learn the fundamentals of Carbon Capture, Utilization and Storage (CCUS) and the role that geophysics plays in the verification of secure, long-term storage of CO2 in the subsurface.

Special Requirements: A Google colaboratory account will be required. It is free (need a gmail account):

Climate change is now recognized as a global threat and rising global temperatures are attributed by climate scientists to increasing levels of greenhouse gases (GHGs) in the atmosphere. In particular, emissions of carbon dioxide (CO2) from the combustion of fossil fuels as well as from other industrial sources are considered to be major contributors to climate change. Carbon Capture, Utilization and Storage (CCUS) includes a range of technologies that can significantly reduce emissions of CO2 during the energy transition to low or zero-emitting energy sources. Carbon capture consists of the separation of CO2 from flue gases at large stationary emitters such as power stations, petroleum upgraders, steel and fertilizer plants, or even captured directly from the air. The captured CO2 can be converted to useful products, such as fuels and carbon fibre, as additives to other products such as cement, or utilized for enhanced oil recovery with a reduced carbon intensity of the produced oil. However, the greatest reduction in emissions that can be achieved in the short to intermediate timeframe is the geological storage of CO2. In this process, CO2 is injected into deep saline formations, depleted oil and gas reservoirs, and even mine tailings that can securely store the CO2 permanently. Canada is very well positioned for CO2 storage at a large scale due to its geology and technical expertise.

Key technical requirements for CO2 storage projects are injectivity, secure containment and conformance of the CO2, and the storage capacity of the injection reservoir; all of which include geophysical surveys for either baseline or time-lapse monitoring. We will review the steps necessary for having a successful CO2 storage project, with an emphasis on the role of geophysics to achieve it. The course will be illustrated with examples from the Carbon Management Canada (CMC) Newell County Facility. The site was developed in the South-East of Alberta by CMC and the University of Calgary, to develop and assess monitoring technologies for CO2 leakage detection. The second day will be a visit of the site.

Marie Macquet is the subsurface research and project delivery manager at Carbon Management Canada (CMC). She graduated with her Ph.D. in geophysics in 2014 from ISTerre laboratory, University Joseph Fourier (Grenoble, France). In 2016, she started with CREWES (University of Calgary) and CMC and began focusing on the geophysical monitoring of the subsurface applied to CO2 sequestration. Her focus is the use of passive seismic and electrical resistivity tomography to monitor carbon storage.

5.Introduction to AVO and Seismic Inversion

Presented by Brian Russell

Course Date:

1 Full Day – 8:00 AM – 4:00PM MST

Monday, November 6th, 2023

Location: TBD

Course Level: Intermediate

Target audience: Exploration Geoscientists

Special Requirements: None

The topics of seismic inversion and AVO (Amplitude Variations with Offset) have a long and interesting history in seismic analysis and interpretation. The two topics are now grouped under the term QI, which stands for Quantitative Interpretation. Their history dates to the 1960’s when post-stack inversion, which transforms stacked seismic amplitudes into acoustic impedance, was first developed. In the 1980’s, we discovered that pre-stack amplitudes could be used to infer fluid properties of the reservoir and this led to the development of AVO analysis, which simply fits a curve to the seismic amplitudes. The equations governing AVO were then extended to inversion, and the pre-stack inversion technique was developed to extract acoustic impedance, shear impedance and density from the pre-stack gathers.

In this course, I will describe the theory of post-stack inversion, AVO analysis, and pre-stack inversion, and will illustrate these techniques using both a simple numerical example, and real data examples from around the world. Before discussing these inverse techniques, I will introduce the topic of rock physics, which will set the groundwork (and the basic geological models) for our study of inversion. Although the primary focus will be on deterministic inversion, in the final sections of the course I will discuss more advanced techniques like stochastic inversion and inversion using machine learning.

Brian started his geophysical career with Chevron in Calgary as an exploration geophysicist in 1975 and subsequently worked Chevron Geosciences in Houston and for Teknica Resource Development and Veritas Seismic in Calgary before co-founding HampsonRussell Software with Dan Hampson in 1987. HampsonRussell is now a subsidiary of GeoSoftware, where Brian is Vice President, GeoSoftware.

Location: TBD

Course Level: Advanced

Target audience: Users of Advanced Quantitative Interpretation technology

Special Requirements: None

This course will cover the theory and basis that underlies elastic AVO and seismic petrophysical Quantitative Interpretation. These methods follow from the elastic moduli (Lambda, Mu) involved in Hooke’s law and elastic wave propagation in reflection seismology, for both isotropic and anisotropic media.

Through a mix of theory, application and case studies, this course will show that by inverting pre-stack reflectivity to various elastic moduli in terms of incompressibility (Lambda) and shear rigidity (Mu), offers a new understanding into elastic wave propagation and reflection seismology i.e. wave equation based AVO, to quantifiably characterize hydrocarbon reservoirs. Concepts of seismic petrophysics and rock physics will be discussed in detail to enable simple to more complex workflows for conventional and unconventional reservoirs.

Integrating seismic reservoir characterization workflows with other geologic and engineering data will be a primary focus.

11. Advanced Seismic Imaging

Presented by Samuel Gray

Course Dates: 2 Full Days

Monday, October 30th, 2023 –8:00 AM – 4:00 PM MST

Tuesday, October 31st, 2023- 8:00 AM – 4:00 PM MST

Location: TBD

Course Level: Advanced

Target audience: Processors and interpreters curious about seismic-wave principles; grad students in math, physics or geophysics; university faculty in math, physics or geophysics

Special Requirements: None

We will investigate several of the principles of wave propagation that form the basis of seismic imaging theory. These include Huygens’ Principle, the Born approximation, Green’s theorem, the principle of stationary phase, and others. We will see how these principles relate to the forward and backward propagation of seismic wavefields, and how they combine with an imaging principle to produce seismic migration. The principles will be explained pictorially; we will use math as little as possible but as much as necessary. Also, if time permits, we will investigate special topics such as resolution, least-squares migration, migration of multiples and more. The course will be highly interactive, with lots of questions and discussion items for the class.
