The Magic of Lame’ By Bill Goodway

Seismic Analysis Adviser EnCana Corportation, Canada

Abstract: The most common parameters measurable in seismology are VP andVS, 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 Lame’. Lame’ 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 Lame’’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 Lame’ moduli, to Newton’s second law that provides density, and their solutions form the basis for AVO used to describe the attributes of the propagating medium. The result gives relations between propagation velocity VP and VS and the intuitively simple Lame’ 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 Lame’ 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 + 2 mu) in the Earth. Extracting the Lame’ moduli from these mixed parameters provides insight into their physical meaning because Lame’ moduli are intrinsic and invariant properties of elastic media.

President’s Corner by Eric Zimmermann

First, I want to thank everyone for their incredible participation and hard work on the different events that we have had this year. I am proud of the work of the society, and the commitment from all of the officers and members is a major reason why we have had such a successful year. As we move into the next part of the year, I want to give everyone some things to think about.

• Newsletter: if you have news to be shared, send it to our editor, Mary Wildman, whose email address is [email protected]

• December meeting: This is an Honorary Lecture, and attendance at these meetings helps us get future SEG speakers.

• Future meetings: We should soon have a list of the speakers for the coming year. • Golf tournament in the spring! • Elections for next year: We need to identify future leaders. Please contact any of your SGS

officers if you are interested in helping run our geophysical society. I count many successes so far this year. The Northshore social and meeting were a great way to expand our service to our geophysical community. The Technical Symposium was a great success, and I think that teaming with the API was a good combination. Our membership push has been very successful, and the introduction of accepting membership payments through PayPal has been beneficial. Our fall social at the House of Blues did not generate the attendance that we had hoped for, so we may reconsider our presentation of that event in the future.

Biography of Bill Goodway, December Speaker

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 being a geophysicist to being the team lead in a seismic analysis group. Following the Pan Canadian 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 advisor 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 co-authored papers at CSEG, EAGE, and SEG conventions and has conducted research workshops on seismic acquisition and processing, borehole geophysics, anisotropy, multicomponent recording, and AVO. Bill received CSEG’s annual Best Paper Award in both 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 served as vice president and president of the CSEG in 2002 and 2003.


Dear Members of the New Orleans Oil and Gas Community, Next April 11th to 14th, The New Orleans Geological Society (NOGS) will host the 2010 AAPG Annual Convention and Exhibition at the Ernest N. Morial Convention Center. This is a tremendous opportunity for The New Orleans Oil and Gas Community to demonstrate our importance as an Industry hub and as an important part of our local community. For example, at the AAPG Convention and Exhibition this past June in Denver, the AAPG website reports there was a total attendance of 7,452, with 260 exhibiting companies. Also, as a reminder of AAPG’s international influence, 85 countries had representative attendees. Some of the countries with the highest attendance representation included the following: Country Attendees United States 6,359 Canada 269 United Kingdom 166 Norway 54 Brazil 52 Columbia 36 China 35 Saudi Arabia 31 France 31 Australia 29 Netherlands 29 Also, the majority of the post-show survey respondents indicated that they would attend the 2010 Annual Convention and Exhibition in New Orleans. To date, financial support for the convention has been robust in spite of financial difficulties faced by many of our industry colleagues. Currently, AAPG is at over 62% of the necessary sponsorship commitments needed to support the essential convention services, but the deadline is approaching for the high visibility sponsorship recognition associated with the printed convention portfolio. We need your financial support to make the 2010 Convention a success. Now is the time, as members of the New Orleans Community and the Oil & Gas Industry, to publicly demonstrate your commitment to bringing the high quality technical program and exhibition that the AAPG has to offer to its members, through your generous financial contributions as sponsors. On behalf of AAPG and NOGS, thank you in advance for your generous support.

What to Do When There’s Nothing to Do______________________________By Tim Maciejewski Local interests/hobbies: Are you getting bored over the weekends? Tired of going to parades and music/food fests? How about attending a local class or meeting to enhance you “hobby’ing” skills. Here is a list of a few local societies or classes I have either attended or know about from others. I am sure a simple web search can bring you in contact with others that I did not mention. New Orleans Gem and Mineral Society: These folks have been around for many years ( now, I am talking about the society, not the members, well… you will see ). The society meets once per month in the Geology department of UNO. Every month they have a speaker, either someone from the club or someone who has expertise not found within the society. They talk about rocks ( of course ), but also about collecting locals, jewelry making, silver‐smithing, beading, faceting… the list goes on. If there is enough interest from the members, they hold classes on beading, jewelry, or whatever there is interest in. About once a month ( or once every two months, depending on the weather ), the club will have a field trip. These will go to nearby locations to look for rocks, minerals, arrowheads, etc. A couple of the trips go to local businesses who deal with stone to see samples from all over the world and to learn how that company uses them. Glass blowing and lampworking: There are at least two locations in the New Orleans area where you can take classes in blowing glass and/or lampworking. It is not as easy as they make it look so don’t be fooled. It took me over an hour and about 10 tries to make a simple glass bead that was round. After a while, you get the hang of working with molten glass, but you will need a lot of practice to make the fine intricate work that I have seen. Once you see what goes into a fine glass art piece, you will see why they charge so much for them. I have never taken a glass blowing class, but we have been in the same room as them and it looks like fun. The location we attended has an open house once or twice a year and they invite anyone who is interested in watching a glass blowing show from the master glass artists. Other local hobbies and interests: Wine and Art: You don’t make the wine; you drink it while the teacher walks you through step by step in creating your own work of art, this may make for some interesting art at the end of the class. Local book stores will have artist signings and readings. Glass stores can have classes on stain glass creation. Liquor places hold classes and tastings from beer to scotch. There are some restaurants in the French Quarter that hold cooking classes. Go to Oktoberfest and ask about the local zymurgy club. There is a lot of interesting hobbies you can become more familiar with if you look around. Now go out and get a new local hobby! Regards, Tim M… [email protected]

December 1, 2009 Here’s hoping everyone had a nice Thanksgiving. The SGS Auxiliary plans to taste the wines of South America at their next get-together on the 11th of December at Ed and Rosemary Austin’s house in Harahan. I look forward to meeting some of these sweet ladies, having spoken to one or two of them on the telephone from time to time. I am trying to get adept at manipulating photographs to include in the newsletter each month, but I have a ways to go before I consider myself good at it. Regardless, I will take some pictures, and maybe one of these times, before my tenure in office expires, I will learn to include some captions! Stay tuned. Speaking of photographs, I’d like to thank Art Christensen for the camera work that he does at nearly all of our functions. This involves traveling from the distant Northshore and getting to our meetings in downtown New Orleans. He sends me his fine pictures in jpeg format, and with very little know-how and a lot of luck, I can usually manage to insert them into the newsletter. Art has not yet “gone digital.” He is a purist, still using film. His pictures really add a lot to our newsletter, and we ALL appreciate the time and trouble to which Art goes in order to provide us with these! We also appreciate all of those companies who re-upped with their advertising in our newsletter. We have generated a little bit of new advertising this year, but our mainstay is our old, faithful, established advertisers. Please browse their ads and call on them for their services and products. Names, phone numbers, and email addresses are often included in their advertisements.

Wishing each of you health and serenity during the holiday season and into the New Year,

Mary
