Duration: two days
This course is designed for geologists and geophysicists with interests in potential fields and regional tectonics. Presented as a two-day seminar, we concentrate on fundamentals for the first day and tackle advanced topics during the second day. Attendees with little previous experience in gravity and magnetics will find the pace comfortable and the concepts quite accessible. Attendees who have already worked with potential field data will find the first day to be a helpful review of basic concepts and the second day to be quite challenging and thought-provoking.
The course will include formal lectures, extensive presentation of case histories, computer-based modeling demonstrations and qualitative interpretation of mapped gravity and magnetic data. The students will have an opportunity to work with the computational software during the workshop period. The course is limited to 30 attendees in order to facilitate group discussion and interaction.

It’s all about how to spot a nut, detect hidden whisky, and fail to find oil with sexual emanations”.
A central goal in exploration geophysics is to provide quantitative estimates of subsurface rock properties in 3D to construct reservoir models. This workshop addresses geophysical inversion in reservoir characterization as it is practiced today and as it will be practiced in the future. It will look at existing and emerging inversion techniques, the impact of new data acquisition, appreciation of uncertainties, and interdisciplinary integration. Full waveform inversion, repeat measurements, such as time-lapse seismic and controlled-source electromagnetic data all offer significant uplift in reservoir characterization, but the challenge of integrating across scales and disciplines remains. We therefore welcome oral and poster presentations addressing the following and other topics in reservoir characterization and rock property and fluid content estimation:
28 February – 1 March
This course will provide information related to recent advances in data acquisition technology, equipment and the methodologies that are being utilized to improve data quality and, in many cases, reduce the cost of 3D survey acquisition. The course is appropriate not only for geophysicists involved in survey design and acquisition, but also for those involved in data processing and interpretation who wish to better understand the potential improvements that can be made. Both marine and land applications will be discussed.

Brazilian Geophysical Society (SBGf), supported by the Society of Exploration Geophysicists (SEG) and the Latin American Geophysical Union (ULG) are organizing in 2010 a Forum to focus discussions on the application of non-seismic methods for Oil and Gas Exploration.
Modern geophysics was born with non-seismic methods when Conrad Schlumberger conceived the revolutionary idea of using electrical measurements to map subsurface rock bodies in 1912.
Almost 100 years later non-seismic methods are still revolutionizing the geophysical world with new ideas and methods to help understand and explore the Earth.
Today, the oil industry emphasizes the use of geophysical techniques that have the least environmental impact. Also, as the large reserves are harder to find and produce, the industry looks for new technologies that can provide crucial information for the exploration and production of these areas in an efficient and more cost-effective way.
We invite examples from offshore and onshore applications of non-seismic methods from South America, Gulf of Mexico, North Sea, Middle East, Russia and others.
The Organizing Committee expects to receive 150 delegates from Brazil and abroad.

Mapping reservoirs based on resistivity and induced polarization derived from continuous 3D magnetotelluric profiling: Case study from Qaidam basin, China

In Sanfu, Qaidam basin, China, traditional geophysical methods have failed to find subtle hydrocarbon reservoirs. In an attempt to predict anddelineate gas reservoirs, we used a type of magnetotelluric (MT) profiling called 3D continuous electromagnetic profiling (CEMP). Electric logs indicate that gas-bearing formations have high resistivity relative to nongas-bearing formations.

This paper presents analytical modeling results for a triaxial frequency-domain electromagnetic-induction (EMI) sensor over a homogeneous earth containing a long linear conductor. Although the conductor studied is intended to represent an underground wire or pipe, it can represent any subsurface, linear geologic structure that can channel current.

Three-dimensional (3D) inversion of magnetic data to recover a distribution of magnetic susceptibility has been successfully used for mineral exploration during the last decade. However, the unknown direction of magnetization has limited the use of this technique when significant remanence is present. We have developed a comprehensive methodology for solving this problem by examining two classes of approaches and have formulated a suite of methods of practical utility.
Leveling HEM and aeromagnetic data using differential polynomial fitting

We introduce a new technique to level aerogeophysical data. Our approach is applicable to flight-line data without any need for tie-linemeasurements. The technique is based on polynomial fitting of datapoints in 1D and 2D sliding windows. A polynomial is fitted to data points in a 2D circular window that contains at least three flight lines.

A major difficulty in electrical resistivity imaging is the identification ofthe lithologic units, especially in the sedimentary environments. The geologic interpretation generally is realized by visual inspection of the final resistivity section. Although sharp boundary inversion techniques based on a local linearization could allow the delineation of interfaces between geologic units, these techniques will succeed only if an initial model already close to the best solution is available.
The Misadventures of Interpreter Sam (SEG Geophysical Monograph Series No. 15) is a collection of the first six years of “Interpreter Sam” columns from THE LEADING EDGE. It contains commentary on both the humorous and serious sides of an interpreter’s day from the point of view of the fictitious Interpreter Sam, our Everyman of interpretation. Sam introduces each chapter with a caricature of himself (an interpretation of his own “reflection,” if you will, created by the talented artist David Carman), and in the epilogue, he offers a special gift to his friends in data processing. This book can be read and enjoyed by anyone who has ever interpreted even a single seismic line, by eager students who aspire to be interpreters, and by nongeoscientists who presume that they know how interpreters think.
The Society of Petroleum Engineers (SPE) and the Society of Exploration Geophysicists (SEG) have formalized an agreement for intersociety cooperation to benefit their global membership through joint events, programs and services. “This is an exciting opportunity for both societies to build on an already strong relationship to enhance technical knowledge exchange globally that will benefit our members and serve the upstream oil and gas industry,” said Behrooz Fattahi, 2010 SPE president.
