Mature Fields - Subsurface IssuesRMGT/MATFIELD

Who should attend?

  • This course provides a comprehensive and practical understanding of methods and issues related to the reevaluation of mature hydrocarbons fields (brown fields) in order to optimize the production and increase the reserves.
Audience :
  • Geoscientists, reservoir engineers, petroleum engineers and asset managers involved in managing and optimizing mature fields.

Level : Foundation
