- 2. Agenda g Workshop Overview SEISMIC STRATIGRAPHY What is it How do we use it This course provides a thorough overview of seismic interpretation, How does it relate to geology especially as used in the oil industry. We will help seismic interpreters to learn to build an effective workflow to cope with the increasing data volumes, as well as the increasing complexity in the SPECTRAL DECOMPOSITION data itself. The topics range from calibration of seismic data using What is it well logs to quantitative interpretation, the principles of volumetric How do we use it interpretation and visualization techniques to reveal geological Gas absorption features inside a 3D volume, using more physically meaningful slides and intuitive concepts rather than concentrating on the mathematics. Examples of seismic interpretation used in reservoir DAY 2 | 7th October 2009 characterization will also be shown. This course is designed for geoscientists and for anyone who would like to interpret seismic data and to understand the potentiality and limitations of using WELL LOG, PETROPHYSICS, ROCK PHYSICS AND seismic data. Attendees should bring with them their laptops INVERSIONS with Excel. IHS software will be provided with a limited license as well well-log data to model. You are also welcomed to bring your own data for modeling purpose. ROCK PHYSICS AND PETROPHYSICS Linear approximations to Zoeppritz equations Acoustic Impedance DAY 1 | 6th October 2009 Reflection Coefficient at zero offset. Reflection Coefficient at different incidence angles Well logs Conversion of resistivity to sonic logs SEISMIC Upscaling Rock properties that can be derived from well data (porosity, SEISMIC DATA saturation) Creating seismic well logs (EI, Lambda-rho, Mu-rho) Seismic Acquisition; Review Gardner’s equations, vs. equations, etc Parameter selections for acquisition such as fold, offset, etc. Velocity and Density of rocks Land, TZ, and marine acquisition Seismic Synthetics Cost versus quality versus time (Project Management) (Upon request attendees will get a better version of this rock Survey/navigation calculator.) Field QC and early stages of processing General conclusions about the different classes of AVO Nyquist and filtering Examine well logs, Vertical Seismic Profiles, check shots how Phase and issues with phase does well data tie to seismic Seismic Processing Formation Tests What is a wavelet Exercise: Using IHS software and well data provided build Fourier Transform an AVO synthetic offset model, and do Biot-Gassmann fluid Stationary versus Non-stationary substitution. Examine the stacking responses of nears, and fars Processing general work flows and ERG Potential problems in seismic processing and seismic data Exercise: Build a rock calculator in Excel and model different Seismic velocities classes of AVO Importance of Automatic high density, high-resolution seismic velocities INVERSION Discuss how velocities can be used for basin analysis and understanding seals Definition Offset dependent tuning Different types NMO stretch and higher order moveout Elastic Look at some case histories illustrating these concepts Lambda Rho Mu Rho Simultaneous Inversion – Density SEISMIC GATHERS, STACKS AND REFLECTIVE ATTRIBUTES Estimating net to gross with inversion Problems with inversions What is a seismic gather Exercise: Do Lambda rho and Mu rho crossplots of well data What is a stack with IHS software What is AVO Different classes of AVO PITFALLS IN AVO Analyze the stacking responses and the AVO attributes Examine how stacks can be used for AVO Guidelines to AVO anomalies Review some case histories Fizz gas Understanding AVO and the need to build AVO models CROSS PLOTTING Examine cross plots Define seismic background, fluid factor, etc Discuss how interactive crossplots work

DAY 3 | 8th October 2009 ABOUT YOUR COURSE FACILITATOR INTERPRETATION Brian Schulte is the owner of GeoPsi Consulting, which specializes in solving technology issues such as AVO modeling, 4D SEISMIC OR TIME LAPSE AVO interpretation, pore pressures and petrophysics. He is a petrophysicist, AVO and pore pressure expert with 20 years of What is 4D industrial experience. What are the criteria for 4D to work Reservoir Simulation Brian was Chief Onboard Processing of Schlumberger. He Multi-component scrutinized the quality and integrity of the seismic field data being Use of AVO with development of a field and field monitoring recorded in multi-million dollar seismic surveys. He was also a senior staff onboard the vessel which made major decisions which PORE PRESSURE AND AVO influenced the overall project. Understanding elementary pore pressure concepts Using pore pressure to analyze seal When he was with BP, Apart from the Upstream Technology Group Understanding the relationship of AVO anomalies to pore as a seismic processing/AVO advisor, Brian brought together BP/ pressure AMOCO technology with ARCO technology to obtain superior results vUtilize a pore pressure calculator to understand pore pressure in seismic processing. He also contributed ideas, concepts and suggestions to the various global networks within BP. Brian worked DIFFERENT STAGES TO A HYDROCARBON DEVELOPMENT extensively with a program called AVEL. This program produced high resolution residual velocities and flattens gathers for AVO analysis. Exploration – generation of a prospect He represented BP at many conferences and trainings, such as BP Drilling – dangers and completion No Drilling Surprises Conference, BP Seismic Quality Conference Appraisal – is it economical to produce and volumetric and and BP 4D Rock Properties course. Brian shared many of his booking reserves experiences, including prestack interpretation and cross plotting Production – Reservoir Drive mechanism, artificial lift, EOR AVO attributes showing the rock physics behind the cross plots. VISUALIZATION In addition, Brian has consulted clients such as Chevron, Stone and EPL in seismic processing, regional AVO analysis and prospect Voxel geo generation.

You will receive a comprehensive set of course documentation to Interpreters enable you to digest the subject matter in your own time. Geologists Technical Support Personnel Seismic Processors Exploration and Data Processing Managers Program Schedule Data Acquisition Managers Academics (Day 1 - Day 3) 08:30 Registration WHY YOU SHOULD ATTEND 09:00 Morning Session Begins 10:40 - 11:00 Refreshments & Networking Break Exploration companies need to be willing to accept and implement 12:45 Luncheon new technology at a faster pace. The slow pace of adoption of 14:00 Afternoon Session begins technology caused many companies to lose competitive edge 15:30 - 15:50 Refreshments & Networking Break over their competitors. High drilling costs force the need for more accurate seismic interpretation techniques. With the increasing 17:00 Course Ends exploration data volumes, interpreters struggle with them, and increasing the need for better interpretation techniques like quantitative interpretations and volumetric interpretation that gives much-admired accuracy to interpreting exploration data. This workshop will help you overcome these important issues with the latest practical interpretation techniques and useful workflows, using practical case studies and exercises to help. The course materials and knowledge shared provide a reference library that you will use throughout your career life.
