2008 BAGS Meeting:
Passive: Microseismic Opportunities over an Oilfield's Life

Passive seismic, especially microseismic monitoring, is to conventional
seismic as a stethoscope is to a sonograph. It is continuous 4D. It is
accomplished by listening carefully to the sounds emanating from the
earth and then diagnosing what is happening down there. Passive seismic
techniques not only can create an image of the reservoir and its
plumbing, but also shed light on how the fluid is flowing through the
Grasping the completeness of the passive science, one can see that it
provides the opportunity to contribute over the lifetime of an oilfield
from discovery to abandonment. Passive seismic can accomplish
reconnaissance 3D exploration at an attractive cost and lead to new
discoveries. Microseismic monitoring of a hydrofrac can and does
provide valuable information on completion and development strategy.
Gas or fluid injection operations for primary or secondary recovery are
prime candidates for passive monitoring to prove regulatory compliance,
validate reservoir conformance, and estimate recovery efficiency.
This lecture will present a view on the history and development of
passive seismic techniques, a discussion of state of the art through
case histories, and a vision on where this technology will play a role
in the smart oil field of the future.
Peter M. Duncan is founding President of
MicroSeismic, Inc., a Houston based geophysical service company. He
holds a Ph.D. in geophysics from the University of Toronto. He began
his career as an exploration geophysicist with Shell Canada before
joining Digicon Geophysical, first in Calgary then in Houston. In 1987,
he helped Digicon found ExploiTech Inc., an exploration and production
consultancy. He was named President of ExploiTech when it became a
subsidiary of Landmark Graphics in 1989. In 1992, he was one of three
founders of 3DX Technologies Inc., an independent oil and gas
exploration company where he served as Vice-President and Chief
Geophysicist. Duncan was 2003-2004 President of the Society of
Exploration Geophysicists (SEG).
