About the Workshop

Despite considerable improvements in seismic data quality and imaging algorithms, velocities and earth models remain the key challenge for depth prediction. In this workshop we focus on all aspects of reducing uncertainties in velocities, including applications in seismic imaging, velocity model building, pore pressure prediction, depth conversion and drilling. We would especially welcome case histories highlighting successes and failures.

Social Programme

Workshop DinnerTuesday 26 April 201618:00 – 21:00 hrsVenue to be announced soon.  Please refer to the event website www.eage.org.

Pre-workshop Short Course

Seismic Velocities & Depth Conversion18 - 22 April 2016, 09:00 – 17:00 hrsInstructor: Mac Al Chalabi

Course DescriptionThe offered course is intended to build up the

standard of the participant to a very high professional level in the field of velocities and depth conversion. The participant should then be able to handle velocities with full competence, rigour and insight for depth conversion purposes and over a wide range of seismic processing and other applications in ex-ploration and production.

EAGE Workshop on Velocities: Reducing Uncertainties in Depths 5

About the instructorDr Mac Al-Chalabi worked four years with the Iraq National Oil Company and nearly twenty years with BP in a wide range of mainly geophysical capacities in petroleum exploration and de-velopment and in research, in UK, The Netherlands, Tunisia, Sin-gapore and Venezuela. Since 1990, after leaving BP, Dr. Al-Chala-bi has been an independent consultant in petroleum exploration and particularly as a specialist in velocities and depth conversion methods. His activity in this specialty covers a wide range of in-terpretational and processing problems in exploration, develop-ment and production projects as well as an advisor and expert witness in issues of equity distribution and field unionization.

* The course has been limited to a maximum of 10 participants in order to war-

rant an interactive setting.

Post-workshop Classroom Laboratory

Gas Clouds and Beyond: Solving Difficult Depth Conversion Problems 28 - 29 April 2016, 09:00 – 17:00 hrsTutor: Alan Atkinson

Course DescriptionThis workshop covers intermediate-advanced

velocity analysis and velocity modelling techniques which are used for depth conversion, and which can also be used for build-ing preliminary depth imaging models. A structured approach is used to simplify hard-to-solve problems. The laboratory includes introductory lectures, case studies and practical problems which will be solved in small teams.

About the instructorAlan Atkinson has over twenty five years of exploration, field development, and production geoscience experience with op-erators in West Africa, South Asia and the North Sea.Specializing in the application of high end geophysics to struc-tural and stratigraphic seismic interpretation, his areas of ex-pertise are reservoir characterization (using pre-stack inversion, AVO analysis) and velocity modelling (pre-stack depth migra-tion and depth conversion).

* The class has been limited to a maximum of 20 participants in order to warrant

an interactive setting.
