An Introduction to Onshore Seismic Data Acquisition

Learn how to plan successful onshore seismic acquisition projects and how to work with contractors to execute these projects.

Description

Participants will learn the steps necessary to plan successful onshore seismic acquisition projects and will also learn how to work with contractors to ensure that projects are executed safely and according to plan.

Duration and Logistics

Classroom version: A 1-day classroom course comprising a mix of lectures (90%) and exercises (10%). An optional workshop where a client’s project data may be reviewed can be added. The manual will be provided in digital format and participants will be required to bring a laptop or tablet computer to follow the lectures and exercises. Multiple choice quizzes will be utilized to reinforce learnings.

Virtual version: Two 4-hour interactive online sessions presented over 2 days (mornings in North America and afternoons in Europe). A digital manual and exercise materials will be distributed to participants before the course. Some reading and several exercises are to be completed by participants off-line. Multiple choice quizzes will be utilized to reinforce learnings.
