Topics: Quantitative Seismic Interpretation/Applications

Seismic Attributes – from Interactive Interpretation to Machine Learning

Kurt Marfurt

In this course, we will gain an intuitive understanding of the kinds of seismic features that can be identified by 3D seismic attributes, the sensitivity of seismic attributes to seismic acquisition and processing, and of how ‘independent’ seismic attributes are coupled through geology. We will also discuss alternative workflows using seismic attributes for reservoir characterization as implemented by modern commercial software and practiced by interpretation service companies. Participants are invited to bring case studies from

Reservoir Geophysics: Applications

William Abriel

The objective of the course is to demonstrate how and why geophysics adds value in reservoir management using examples from multiple geological environments (deepwater turbidites, onshore fluvial, near shore deltaics, carbonates). The course is designed to examine and illustrate the dependencies of geology and engineering data on geophysical applications during reservoir management and to expose participants to the variety of geophysical tools used in reservoir work. The participants will become familiar with the application and

Petrophysics and Geophysics Relevant to CO2 Enhanced Oil Recovery

William Harbert

In this SEG course the basic physics relevant to CO2 are presented, including the descriptions of gas, liquid and super critical phases (scCO2). Enhanced oil recovery (EOR) was a natural development in the production of hydrocarbons. In this course topics relevant to the utilization of CO2 to enhance oil recovery are presented. CO2 is an especially appealing EOR injection agent. In this SEG course the basic physics relevant to CO2 are presented, including the descriptions

Integrating Seismic, CSEM and Well Log Data for Reservoir Characterization

Lucy MacGregor

This course will concentrate on three contrasting methods: surface seismic, marine controlled source electromagnetic (CSEM) and well-log data. Improved reservoir management and production optimisation demands require accurate characterisation of reservoir properties and their changes through time. Advances in geophysical data acquisition and interpretation have led to significant improvements in the remote imaging of earth structure and properties. However, when only a single data type is considered, ambiguities in the interpretation can remain. Integration of disparate

Geophysical Applications of Time-Frequency Analysis

Marcílio Matos

This course shows how basic knowledge of joint time-frequency (JTF) analysis theory associated with pseudo computer programming can help geoscientists to take full advantage of their real world applications. Several JTF exploration geophysics applications are detailed, like spectral decomposition, data compression, filtering, etc. Starting from Fourier theory review, advanced time-frequency techniques are introduced by showing practical applications and by hands on introductory computer programming.

Dynamic Reservoir Characterization: Multicomponent 4D

Steven Roche and Thomas Davis

Purpose of the course is to provide real case studies of multicomponent seismic applications towards an actual dynamic reservoir problem. Course participants will view real data and learn from the experiences gained within the Reservoir Characterization Project at Colorado School of Mines. Topics include geology, reservoir characteristics, rock physics review specific to the problem, multicomponent overview, and details of multicomponent (9-C) seismic data acquisition & processing. Main part of the course will be the integration

Construction of fractured reservoir models for flow simulation incorporating geology, geophysics, and geomechanics

Reinaldo Michelena, Chris Zahm, and James R. Gilman

Objectives Flow models have the purpose of explaining and forecasting reservoir performance that can help plan the development and exploitation of the resource. Conventional and unconventional naturally fractured reservoirs are particularly difficult to model due to the interconnectivity of matrix and fracture properties. Unconventional reservoirs pose the additional challenge of accounting for natural fractures that can become conductive during hydraulic stimulation. This class explains the steps necessary to build fractured reservoir models using sound stratigraphic

AVO: Seismic Lithology

Mike Graul and Fred Hilterman

The concept of using amplitude variations with offset (AVO) for the direct detection of hydrocarbons was first reported to the geophysical industry in 1982 by Bill Ostrander. Since then, the interest in this technique has continued with multiple sessions at the SEG Annual Meeting, special issues of The Leading Edge, dedicated seminars, and specialized processing and interpretation packages. While there have been many significant technical advances and improvements in our understanding of this subject, there is

A Practical Understanding of Inversion for Exploration Geophysics

John Bancroft

The course will present the basic methods of seismic inversion in a simple manner and use diagrams and figures to illustrate the principles.  Some mathematics will be used and explained with images where possible.  The course will begin with simple examples of inversion processes and end with a short discussion on Full Waveform Inversion (FWI). Inversions are often approximated with processes that are referred to as transpose processes. A number of related topics will be
