About the speaker:

   Dr. Bj?rn N.P. Paulsson received a Fil.Kand. Degree in Geology from U. of Gothenburg, Sweden, in 1976 and a Ph.D. in Geophysics and Rock Mechanics from the University of California at Berkeley in 1983. For his Ph.D. thesis he developed a time lapse seismic technique to characterize and monitor a fractured rockmass for the storage of high level nuclear waste.

He founded Paulsson, Inc. (PI) in 2009 to continue his work developing and applying his unique borehole seismic technology onto the reservoir imaging problems in the oil and gas industry. He founded Paulsson Geophysical Services, Inc. (P/GSI) in 1997 as a spinoff company from Chevron Oil Field Research Company to commercialize a unique downhole seismic source he developed while at Chevron. At Paulsson Geophysical he invented and developed large seismic receiver array technology for boreholes. Paulsson Geophysical was the first company to introduce large, over 100 3C levels, borehole seismic arrays to the geophysical industry for the recording of large 3D VSP and cross well surveys. Between 1984 and 1997 he was a Senior Research Geophysicist with Chevron Oil Field Research Company (COFRC) introducing borehole and time lapse seismic technology to Chevron Corporation.

Between 1983 and 1984 he was a postdoctoral fellow at University of California at Berkeley. Between 1977 and 1981 he was a Senior Research Engineer with Lawrence Berkeley Laboratory at Berkeley developing borehole seismic imaging technology for the safe storage of high level nuclear waste.

Bj?rn's interests include time lapse monitoring of fracture rock masses, high resolution characterization and monitoring of oil and gas reservoirs and monitoring and characterization of earthquake zones. He holds 8 patents on borehole seismic instrumentation and has published more than 50 papers and reports on various aspects of borehole seismic imaging and instrumentation. Bj?rn received Chevron's Chairman's award for his development of a powerful non destructive downhole seismic vibroseis source for cross well and reverse VSP imaging. He was an SPE distinguished lecturer from 1990 to 1991. Bj?rn has been very active in SEG and organized the first SEG Development and Production Forum in 1991. From 1992 to 1994 he was the chairman of the SEG D&P committee. Bj?rn also organized the first joint SEG - SPE forum on reservoir geophysics.
