E-263 - Advanced Carbonate Reservoir Characterization

5 jours RES/ADVCARB
Niveau
Expertise
Public
  • Experienced geologists, geophysicists, petrophysicists, reservoir engineers involved in carbonate reservoir characterization
Finalité
  • To deepen understanding of ways and means for describing carbonates from cores/outcrop analogues, logs, and seismics; and, ultimately, integrating data efficiently for reservoir characterization and static modeling
Objectifs
  • To assess steps followed to characterize carbonate reservoirs and build a static geological and petrophysical model
  • To appreciate the contribution of carbonate sedimentology and sequence stratigraphy to the model
  • To assess the significant impact of carbonate diagenesis on pore-space
  • To understand the complexity of carbonates’ Phi-K properties and link geological observations and petrophysics
  • To review about rock-typing processes integrating sedimentology and petrophysics data
  • To develop skills in building efficient workflows for carbonates reservoir characterization
Les + pédagogiques
