SEG's J. Clarence Karcher Award 2003
The J. Clarence Karcher Award is being given to Edward Jenner in recognition of his contributions to the technology of exploration geophysics in the area of azimuthal 3D seismic processing with emphasis on the relationships of azimuthal variations of AVO attributes and velocity to reservoir properties.

There are many technical and business chasms to transcend in our industry. One class of chasm that is hardest to cross is the one involving moving well reasoned theory and laboratory experience into effective production and finally economic impact. Edward Jenner has accomplished this crossing with techniques to observe and interpret azimuthally varying Pwave properties in reflection seismic data, an anisotropy problem that turns out to have been plaguing processing and interpretation since the dawn of reflection seismology.
In short, Ed discovered a way to analyze and linearly fit traveltimes for azimuthally varying NMO and was then able to separate and linearly fit amplitude variation with offset and azimuth (AVOA) using his own recognition of linearity in Rüger’s 1996 formulation of AVOA. In addition Ed recognized the induced coupling of the azimuthal AVO to the azimuthally varying NMO inherent in the current techniques for azimuthal analysis. (See his 2001 articles in THE LEADING EDGE for detail.) He also demonstrated the analysis conundrum when dealing with both structure and azimuthal anisotropy within the same data set.
Ed started his education in astrophysics and followed this path until he made the decision to take an internship at BP in 1994. Although Ed’s experience had not trained him for the opportunity, he found that he loved the work. In 1994, Ed started on his path as a geophysicist working on reflection profiling of the earth’s crust at the University of Leeds, where he received his master’s in Exploration Geophysics. Ed then attended the Colorado School of Mines (CSM) where he worked under the masters of theoretical seismic anisotropy.
There, he became familiar with the language of anisotropy from not only his professors (Ilya Tsvankin and Vladimir Grechka), but also from his predecessors Andreas Rüger and Tariq Alkhalifah. He made the decision to concentrate his PhD in the applied aspects of reservoir geophysics under Tom Davis. However, Ed did not leave behind the anisotropy. Instead he planned on leveraging anisotropy to explain the reservoirs he was researching. The only question was the how.
In his final year at CSM, Ed joined AXIS Geophysics for the summer. His project on a BP 3D data set was to analyze a reservoir for fracturing using AVOA. Within a matter of weeks, Ed discovered the significance of the azimuthally varying velocities, and how to correct the seismic data for the time distortions. Also within this time, he coded the linearized solutions for both NMOA and AVOA that led to the first nonazimuth sectored data volumes of both properties ever created. On his return to CSM, his PhD in reservoir fracture analysis quickly progressed with the use of his new techniques. He graduated in 2001 having made great contributions to the Reservoir Characterization Project on Weyburn oil field in Canada. Ed also built a foundation from which many of the other students in the Reservoir Characterization Project could follow toward a much deeper understanding of fractured oil and gas reservoirs.
Ed has now started his career in geophysics as one of the new masters in anisotropy working with GMG/AXIS (a business unit of Input/Output Corporation). He is active in the SEG and his local chapter, the Denver Geophysical Society, and he participates in assisting the geophysics students at CSM through mentoring and lectures. Ed and his wife Lucy enjoy both a new house in Denver, Colorado, and a new son, Graeme. Ed thrives on the outdoors where he rock climbs, hikes with his family, and mountain bike rides all with the same enthusiasm he puts into geophysics.
