The Interpreter’s Guide to Depth Imaging

Scott MacKay

Duration  Four, half-day webinar course Summary An interpreter-oriented approach to the theory, practical application, and interpretive aspects of depth imaging. The course begins with understanding the nature of velocities and reviews time-to-depth conversion as a prelude to understanding the limits of time migration. Next, is an intuitive overview of migration theory, Kirchhoff (ray) versus RTM (wave) algorithms, tomographic velocity updates, and advances in full-waveform inversion for the near-surface model and velocity updating. This course introduces

Seismic Diffraction – Modeling, Imaging and Applications

Tijmen Jan Moser

The course covers both the forward and inverse problems of seismic diffraction imaging. The imaging of seismic diffraction is a rapidly emerging technology. This course will focus on the forward problem, extending from the discovery of the phenomenon of diffraction and the basic formulations of Fresnel and Kirchhoff to the evolution of modern seismic diffraction modeling. Diffraction imaging will be covered from the early works in the 1970s up to the present state of the art.

Introduction to Applied Depth Imaging

Ruben Martinez

This course provides an understanding of the basic concepts and practical aspects used for building velocity models and generating seismic images. Hydrocarbons are increasingly more difficult to find because conventional and unconventional reservoirs are often present in areas with complex structural and stratigraphic characteristics. The geological complexity has motivated a significant paradigm shift from time imaging towards the extensive use of seismic depth imaging. Seismic depth imaging improves the definition of structural and stratigraphic frameworks

Full Waveform Inversion

Mrinal K. Sen

This course is designed for technical personnel of the oil and gas industry who are engaged or expected to be involved in seismic imaging, accurate velocity analysis and interpretation. Seismic Inversion plays an important role in building reservoir models by integration of different data types. Duration One to two days Intended Audience Intermediate level Prerequisites (Knowledge/Experience/Education Required) The course is designed to be followed by anyone with some background in seismic processing including imaging. Basic

Concepts and Applications in 3D Seismic Imaging

Biondo Biondi

The primary objective of this course is to provide a broad and intuitive understanding of seismic imaging concepts and methods that enables geoscientists to make the appropriate decisions during acquisition, processing, imaging, and interpretation projects. Seismic images are the basis of crucial exploration, development, and production decisions. Optimal use of these images requires a full understanding of the seismic imaging processes that create them, from data acquisition to the final migration. The primary objective of

An Introduction to Migration and Velocity Model Building

Ian F. Jones

The course will commence with an overview of different migration schemes, and cover the motivations for building detailed velocity models, and briefly discuss the inherent limitations on our ability to build a detailed model. Current-day practice will be covered, exemplified via many case-studies, and we will briefly discuss the less well known and emerging techniques. The approach will mostly be non-mathematical, and will rather try to concentrate on an intuitive understanding of the principles, and

Acoustic & Elastic Seismic Modeling and Imaging (Reverse-Time Migration)

Phil Bording

This course deals with the analysis and application of the acoustic and elastic wave equations in exploration seismology. In particular, the course focuses on the finite-difference modeling of the full wave equation and its application to forward modeling and migration. Duration Two days Intended Audience Entry level to Intermediate Prerequisites (Knowledge/Experience/Education Required) The course will show many examples for the seismic modeling and migration some with animations. The addition of elastic modeling and migration will

A Practical Understanding of Pre- and Poststack Migration

John C. Bancroft

The first course is three days and covers the basic algorithms of poststack migration then discusses issues related to migration such as topography, frequency content, or parameters, to build a foundation for the following prestack course. The second two-day course deals with the prestack nature of migration and its superior capability of imaging the subsurface. Duration Two to five days Intended Audience All levels Prerequisites (Knowledge/Experience/Education Required) This course is designed to be followed by
