E-219 - Basin Modeling: Thermicity, Maturation & Migration

5 days BAS/TEMIS
Level
Proficiency
Audience
  • Junior petroleum exploration geoscientists, multidisciplinary-team managers
Purpose
  • To provide 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
  • To understand source rock maturation and hydrocarbons generation
  • To assess most significant basin modeling parameters for regional basin model construction (with TEMIS1D™)
  • To understand hydrocarbon migration processes (with TEMIS2D™) and to evaluate the hydrocarbon potential of a given area
Ways and means
  • Afternoon sessions are devoted to case studies based on non-proprietary data provided by IFP
  • Use of the software programs TEMIS1D™ and TEMIS2D™, 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
