Course Description

The material is organized into 6 lectures and 2 student problems for a total of 16 hours

The first lecture introduces the life cycle of reservoir management, what economic drivers are important in each cycle and how geophysics adds value. This includes concepts of uncertainty and value of information (VOI) calculation.

This is followed by a lecture on the role of specific geophysical applications in discovery and delineation including the introduction of key well information, geological facies modeling and well ties. A case history is presented showing the difference between 2D and 3D AVO for delineating an oil discovery. The third section is a student hands-on problem for choosing well locations for delineating a deep water sub-salt discovery. Post-stack and pre-stack 3D seismic data are included. The actual delineation results are shown.

The following section is presented on the role of geophysics in development. This concentrates on the value of seismic attributes (inversion, spectral decomposition, quadrature, …) showing their application to reservoir development projects.

The fifth section covers production and the application of geophysics. This includes seismic response to field production, a workflow for 4D, and reservoir monitoring case histories.

This is followed by a second student problem of a continental shelf project. The problem is presented with production drilling history and an initial 3D survey showing production effects in an oil reservoir. The students are asked to locate infill wells. Results are shown including a second time-lapse 3D survey and actual infill results.

The seventh section is a description of reservoir geophysics in heavy oil environments. Production problems unique to heavy oil are discussed along with geophysical technologies to address them, including time-lapse seismic, cross-well seismic, and cross-well electromagnetics. The final section covers reservoir geophysics in carbonates. This includes reflection systems in carbonate facies, property estimation of carbonate reservoirs from seismic data. Case histories are presented including 4D reservoir monitoring of CO2 injection.


William L. (Bill) Abriel is a geophysical consultant at Orinda Geophysical LLC., Bill began his work in the industry with Chevron in New Orleans in 1978, and was the geophysical lead for Chevron in many oil and gas basins around the world for over 37 years. His expertise lies in the application of new technology to active projects including geophysical acquisition, processing, interpretation, integration, team building, project management and strategic research.

Abriel has participated in a variety of SEG activities and is currently the president elect. He has performed editorial work for GEOPHYSICS, TLE and INTERPRETATION, served on numerous SEG committees, including Development, Membership, Research, Global Affairs, and Distinguished Lecturer, was the SEG Spring Distinguished Lecturer in 2004, and the Distinguished Instructor in 2008. Abriel is a founding and past board chair of the SEG Advanced Modeling Corporation (SEAM). He was named a life member of SEG in 2007.

Bill received a B.S. in geosciences and an M.S. in geophysics, both from Pennsylvania State University, where he was a founding member of the SEG student section and earned four varsity letters in lacrosse
