Chapter
Lafayette Society of Petrophysicists And Well Log Analysts
 The Lafayette Chapter holds its regular meetings on the second Thursday of the month from September through May. We meet at the Lafayette Petroleum Club. The cost per meeting is detailed below with lunch included in the cost. There is no annual fee to join the Lafayette SPWLA, however, anyone interested in joining the parent organization is urged to do so by clicking on the New Member link under Quick Links.
Next Meeting : The first meeting of the 2010-2011 session will be held Thursday September 9th at 11:30
Speaker : Roland Chemali, Halliburton - Houston, TX
Roland Chemali is Distinguished Speaker SPWLA 2004 and 2008 and Distinguished Lecturer SPE for 2010-2011. Chief Petrophysicist for Sperry Drilling, Roland earned engineering degrees from the Ecole Polytechnique of Paris and from the French Petroleum Institute and a Master’s in Mathematics from LSU. Roland has co-authored over 50 papers and patents in the area of formation evaluation and geosteering. He has received the Technical Achievement Award from SPWLA and is currently serving as VP technology for SPWLA.
Topic : Formation Evaluation and Structural Dip Determination Using Tilted Coils LWD resistivity
Laminated formations exhibit a peculiar resistivity pattern whereby electrical current finds it easier to flow along the layered surfaces rather than perpendicular to them. This phenomenon is known as electrical resistivity anisotropy. The word anisotropy is hard to say but easy to understand.
Resistivity anisotropy has two major sets of applications in formation evaluation. For reservoir evaluation in turbidites for instance, depending on the relative contrast between the sand laminations and the shale layers, resistivity anisotropy helps evaluate with greater accuracy the hydrocarbon content. This application is valued by the petrophysicists and was initially pioneered by Thomas Steibert. The second type of application regards the determination of structural dip. By identifying the preferential orientation and direction of current flow, it is possible to estimate the relative dip of the layered formation with respect to the wellbore.
In order to fully exploit the measurement of resistivity anisotropy it is important to determine both resistivity components, namely Rh parallel to the bedding, and Rv perpendicular to the bedding. It is also important to identify the inclination and azimuth of Rv. Azimuthal deep resistivity LWD coil arrays with tilted receivers have that capability but only for a restricted range of high relative dip angles. A newly developed sensor with both tilted transmitters and tilted receivers is expected to cover a much broader range of applicability from vertical wells to high angle wells.
President's Message :
Welcome to the 2010 - 2011 SPWLA season! I hope everyone had a safe and enjoyable summer vacation. The first order of business for the Lafayette SPWLA is the 2010 Golf Tournament on Friday, October 8, at Spanish Trail Golf Course. We will only have one chapter meeting before the tournament this year, so we are trying to get the word out early. Jeff Smith of Weatherford is our new Golf Tournament Chairman, and has done a great job of getting a date and sponsors for the tournament. What we need now are teams! Get your team registered as soon as possible. Entry fee remains at $300 for a 4-person team. This is our major fund-raising activity for the Scholarship Fund, so we need everyone’s participation. I realize that conditions are not optimal in the industry right now, so it may take a little extra “boss management” effort to get approval.
Our first Lafayette chapter meeting will be on September 9, at the Petroleum Club. We will begin at 11:30 and be finished before 13:00. Lunch prices remain the same, $20 with reservation and $25 without reservation. Continuing our Lafayette SPWLA tradition, students eat free.
The Lafayette Chapter board for 2010-2011 looks a lot like it did in 2009-2010, with some key additions. As mentioned above, Jeff Smith has taken on the Golf Tournament Committee responsibilities, assisted by Brent Labat, Jeff Danby, and Kenny Inzerella. Returning officers include: Tom Stafford – VP Technology, Rick Goode – VP Membership, Dr. Asad Hayatdavoudi – Academic Advisor, Joe Beck – Secretary/Treasurer, Jon Hebert – Webmaster, Lauri Hardwick – Reservations & Newsletter, and Jeff Prilliman – President. Leading the Scholarship Committee will be Bob Peatross, assisted by Joe Beck and Dr. Hayatdavoudi. Returning to active status is Carlos Contreras – Director.
Be sure to check out the new and improved SPWLA website at http://www.spwla.org/chapter/lafayette. Thanks to John Hebert and Lauri Hardwick for their hard work in creating our new chapter page. There was more new work than “cut and paste” to put this new website together, so be sure to thank John and Lauri. The Formation Water Resistivity information is in Excel rather than a scanned PDF which makes it searchable and much smaller to download. All the links we had in the previous web page have been restored.
Our talk this month will be delivered by Roland Chemali who is currently with Halliburton in Houston. His talk will discuss formation evaluation and structural dip determination using tilted coils LWD resistivity. Resistivity anisotropy has been a well-known formation characteristic for many years, but can still be difficult to understand. Roland will give us a clear explanation of the vertical and horizontal components of the resistivity measurement and demonstrate some innovative uses of these values.
Please make reservations by noon on Wednesday prior to monthly meeting. For reservations please
contact Lauri Hardwick via e-mail or by phone at PathFinder Energy (337) 572-2224.
