MSc university University of Calgary

William Nicholas (Bill) Goodway obtained a B.Sc. in geology from the University of London in 1977 and a M.Sc. in geophysics from the University of Calgary in 2001. Prior to 1985, Bill worked for various seismic contractors in the United Kingdom and Canada. Since 1985, Bill has been employed at PanCanadian Petroleum within the Geophysics department in various capacities from geophysicist to being the team lead of a seismic analysis group. Following the PanCanadian and AEC merger to form EnCana in 2002, Bill has worked in the Frontier and New Ventures Group and more recently in Canadian Ventures and Gas Shales, as an adviser for seismic analysis. In this position, Bill is involved in virtually all aspects of applied seismic exploration from acquisition design and processing to experimental special projects and new interpretation methods. He has presented and coauthored a number of papers at CSEG, EAGE, and SEG conventions and research workshops on seismic acquisition and processing, borehole geophysics, anisotropy, multicomponent recording, and AVO. Bill received CSEG's annual Best Paper Award both in 1994 and 1997, the CSEG convention Best General Paper award in 1996, and the CSEG convention Best Technical Paper award in 1997. In 2008, Bill was the recipient of the CSEG Medal, the Society's highest award. He is a member of CSEG, SEG, EAGE and APEGGA as well as the SEG Research Committee. In addition, Bill was elected vice president and president of the CSEG for the 2002/2003 term

SEG Reginald Fessenden Award 2016 [1]

William Nicholas (Bill) Goodway is being recognized for his development and promotion of lambda-rho-mu inversion technology. Because of his efforts, this seismic inversion concept has become a valuable exploration tool resulting in documented cases of improved drilling success. The popularity and widespread use of Goodway’s inversion procedure justifies his being acknowledged with the Reginald Fessenden Award.

Bill Goodway’s oil and gas career began with his graduation from University College London with a degree in geology. His first foray into the oil and gas industry was in the North Sea acquiring marine seismic data. He moved to Canada in 1982 where he was immediately at the forefront of seismic technology. In constant pursuit of improving seismic exploration techniques, Bill would leave no stone unturned in his analysis of seismic data. He eventually turned his sights to amplitude variations with offset and its interpretation. At PanCanadian, he was given the opportunity to delve into the finer points of exploration geophysics. This fortunate combination of managerial foresight and Bill’s passion for knowledge led to one of the cornerstones of what is known as quantitative interpretation.

The first investigation of lambda-mu-rho, or LMR, was done internally at PanCanadian in 1996 and presented at the 1997 CSEG convention. During this time, Bill pursued postgraduate studies where his thesis, “Elastic-wave AVO methods,” summarized the early learnings and applications of LMR. While developing the framework for LMR, the application of the method was soon prevalent at PanCanadian. Drilling locations were scrutinized and high-graded. The LMR workflow gave seismic data not only the ability to map geomorphology, but also brought forth the ability to estimate lithology, porosity, and hydrocarbon presence — something not commonly seen in the last part of the previous century. From onshore exploration and development of clastic and carbonate reservoirs to offshore exploration, the use of LMR increased success rates and helped in discoveries in the Western Canadian Sedimentary Basin, offshore Nova Scotia, and the Gulf of Mexico. Since that time, LMR technology has been applied to many different exploration and development plays worldwide. With the advent of unconventional resource plays, LMR has still proved to be valuable as it interfaces well with geologic, petrophysical, and geomechanical applications.

LMR is a result of Bill’s passion for seismology, and is only a part of what has been a distinguished career. Bill is always willing to partake in discussions and explore new ideas and concepts. He has championed geophysics as an important role in the industry and was an early advocate for its use with the emergence of unconventional shale gas. Bill has been a mentor and teacher to many and has been generous with his time communicating his ideas and theories. Perhaps the greatest contribution of LMR was in the conversation it has initiated. In the face of controversy, Bill has presented his findings at technical conferences, elicited many debates on the application, and, as a result, forwarded a deeper understanding of reservoir characterization from an elastic property perspective. The understanding of reservoir characterization from seismic data has been enhanced, and Bill has been a leader in this regard. Receiving the Reginald Fessenden award commemorates Bill’s work and the advances he has pioneered.

The Magic of Lamé

The most common parameters measurable in seismology are VP and VS, being the propagation velocities of compressional P-waves and shear S-waves in elastic media. However, these measured quantities are composed of the more fundamental rock parameters of density and two moduli termed lambda and mu, introduced and named after the 18th century French engineer, mathematician, and elastician Gabriel Lamé. Lamé also formulated the modern version of Hooke's law relating stress to strain in its general tensor form, thereby creating the basis for the science of materials, including rocks. Interestingly and most notably, only Lamé's moduli lambda and mu appear in Hooke's law and not Young's modulus, the bulk modulus, or any other common modulus.

The application of seismology to measure or describe rocks and fluids is based on the physics used to derive propagation velocity that originates with the elastic wave equations. These wave equations equate Hooke's law, providing the Lamé moduli, to Newton's second law that provides density and their solutions form the basis for AVO used to describe attributes of the propagating medium. The result gives relations between propagation velocity VP and VS and the intuitively simple Lamé moduli of incompressibility, lambda, and rigidity, mu. Consequently lambda and mu afford the most fundamental and orthogonal parameterization of elastic seismic waves to extract information about rocks within the Earth.

The historical development of seismology at widely different scales has led to the use of a large and confusing array of parameters, which are usually complicated functions of the Lamé moduli. This includes Poisson's ratio, Young's and the bulk modulus, as well as standard AVO attributes such as intercept and gradient, that arise as a result of the media's form and its measurement environment. For example, the same rock will deform volumetrically as a function of the bulk modulus, or longitudinally as a function of Young's modulus, or as a function of the nameless P-wave propagation modulus (lambda + 2mu) in the Earth. Extracting the Lamé moduli from these mixed parameters provides insight into their physical meaning, because Lamé moduli are intrinsic and invariant properties of elastic media. Examples of this from the fields of earthquake seismology, AVO, and passive microseismology will be presented.
