E-128 - Basin Modeling: Thermicity, Maturation & Migration

5 days GEO/TEMIS
Level
Proficiency
Audience
  • Junior petroleum exploration geoscientists, multidisciplinary-team managers.
Purpose
  • This course provides an in-depth and practical understanding of thermal basin modeling in a comprehensive workflow, including modeling of oil maturation and hydrocarbon migration, and leading to the assessment of hydrocarbon potential of an exploration block or a prospect.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • understand source rock maturation and hydrocarbons generation,
  • assess most significant basin modeling parameters for regional basin model construction (using the 1D module of TEMISFLOW™),
  • understand hydrocarbon migration processes (using the 2D module of TEMISFLOW™) and evaluate the hydrocarbon potential of a given area.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Afternoon sessions are devoted to case studies based on non-proprietary data provided by IFP.
  • Use of the software program TEMISFLOW™ (maximum 2 participants per workstation).
  • By the end of each afternoon, participants generate short reports which are assessed the following day.
  • Participants have the alternative of using their own data.
  • Upon request, the course can make use of a company’s regional dataset, provided the latter is made available in advance.
