Course objectives

Upon completion of the course, will know the basics of acquiring and processing borehole seismic data. They will also be familiar with the latest borehole seismic techniques in:

a) High resolution imaging using 2D and 3D VSP surveys
b) Anisotropy determination and fracture analysis
c) Reservoir monitoring using time lapse VSP and crosswell seismic
d) Alternative acquisition schemes such as SWD and DAS

Participants will have a better understanding of the role of borehole seismic techniques in hydrocarbon exploration and production. They will be able to more knowledgeably participate in the design, planning and execution of advanced surveys and be comfortable with the interpretation of these surveys.

Participants' profile

The course is targeted toward those who have a basic understanding of surface seismic acquisition and processing, but only limited knowledge of borehole seismic. The course is designed to help participants identify borehole seismic solutions to common seismic interpretation problems.

The course will also be useful for those geophysicists needing higher resolution images than surface seismic can provide, and those geophysicists who need to validate seismic processing parameters and imaging models using borehole seismic.

The course is also relevant for geophysicists wanting to learn how to use borehole seismic as a cost-effective reservoir monitoring tool.



We assume participants have knowledge of seismic response to earth reflectivity. Participants should be aware of common well logging services.


About the instructor

Allan CampbellGraduated 1984 from the Northern Alberta Institute of Technology in Edmonton with a diploma in Earth Resources Technology and, after a spell in Dresser Atlas, in 1990 from the University of Calgary with a BSc with a major in Geophysics.

In 1990, Allan started his 25-year career at Schlumberger in Calgary. Skills were developed in borehole seismic processing starting from basic check-shots up to the most complex 3D VSPs.

In 1997, Allan moved to Houston Texas, to open a new borehole seismic processing center. The center rapidly evolved into a global center of excellence for VSP processing. Allan helped Schlumberger fully develop 3D VSP processing capabilities.

2010 to 2015 saw the development of many innovative techniques. The integration of borehole seismic data into the processing of surface seismic, to improve the resolution and depth control in seismic images, was finally realized. VSP is now routinely used to detect and characterize fractures, to estimation of the elastic properties of rocks, and to monitor the changes in reservoirs due to both enhanced recovery methods and storage of CO2.

From 2016 to the present, Allan has been working as a geophysical consultant with VSP Consultants LLC. Projects have included work for major operators and service companies, supervising VSP processing projects. Interesting work is also being done on drill bit seismic in hard rock mining environments. VSP Consultants is also offering borehole seismic training courses to the oil and gas industry.
