RESERVOIR GEOPHYSICS
 
Location: Dubai, UAE.
 
Course Dates: June 23-27, 2019
 
Instructor: Prof. Jose Regueiro S., Ph.D., Colorado School of Mines / Geophysicist / Professor / Consultant / Instructor.
 
Who should attend: 
This course is intended for geophysicists, geologists, and reservoir engineers, with some intermediate knowledge of the seismic reflection method.
 
Course benefits;
At the end of this course, the participants should we able to work, and contribute, as much as the data quality allows, within a reservoir characterization team, by providing important information obtained from the detailed analysis of the seismic data. At the end, helping to generate the best possible reservoir model.
 
Objective:
To describe the principal processes by which seismic data can be incorporated in the definition of a reservoir model.
 
Duration: 24 hrs. (theory and examples) + 16 Hrs. workshop
