Course will be held via Zoom: 11–13 August 2020, 8:00 am–12:00 pm (CDT)
The lecture content provides a summary of the fundamentals of deep marine systems. The principal goal of the course is to provide subsurface interpreters with a methodology and hands on experience in seismic, logs, and core interpretation of deep-water deposits.
The course is intended to generate instructive discussion among experienced professionals, moderated and guided by the tutor. Exercises will be assigned each day to reinforce the lectures and class participants will have until the following morning to complete exercises. Results will be reviewed by participants and instructor prior to the next morning’s lecture. Instructor will be available informally to answer questions throughout the day. Final course day exercises will be reviewed in a one-hour block of time on following the last day of lecture.
