CREWES Overview

Advanced research and education in geophysical exploration in partnership

with the resource industry

Specifically, to develop seismic and logging methods to image and monitor

the subsurface and its fluids

CREWES People & Funding• 5 faculty investigators, 12 research

geophysicists and support staff• 32 graduate students• Supporters

– 30 industrial sponsors– NSERC (Gov’t of Canada)– Alta. Govt.

• Graduated over 85 M.Sc. & Ph.D. students, 6 start-up companies, numerous 3/4C seismic surveys, 3 SEG products

CREWES deliverables:Reports, software, data, course

Exploration needs and seismic methods

1) Subsurface structure

2) Lithology & fluids

3) Monitor changes

What are we trying to do, again?

• Provide better structural images of the subsurface

• Determine lithologic information (rock type)

• Describe rock properties (poro., fracs, perm.)

• Estimate fluid content

• Monitor reservoir changes

• Help find & recover underground stuff!

And now, presentations, papers, & posters on….

• Geophone/accelerometer theory & testing• Field and lab data acquisition• Wellbore (logs & VSP) geophysics• Wave propagation (mathematics & modeling)• Seismic data processing, imaging, & inversion• Interpretation & case histories
