Course Description

This course is designed to cover comprehensive carbonate & fracture evaluation methodologies, from log analysis to full well test integration. Holistic plan of action for the acquisition and integration of carbonate petrophysical data, highlighting problems and their solutions are presented throughout the course. Daunting prospect of managing fractured carbonate 'complex' reservoirs is fully covered. 

Course Objectives

  • Comprehending fractured carbonate reservoirs and their data response implications
  • Detecting and handling of extreme pores, vugs, fractures and oil wetness occur in carbonates 
  • Identifying and treating fractures in carbonate reservoir  
  • Troubleshooting fractured reservoirs well tests and other critical data 
  • Identifying errors that has impact on results 
  • Acquiring and integrating key drilling, mudlog, core, special log and well test data
  • Evaluating carbonate log data and integration of log data to other data types such us core data, capillary pressures with logs

Who Should Attend?

  • Petrophysicists
  • Geologists
  • Operations Geologist
  • Engineers or core analyst who uses or creates petrophysical results for carbonate or 'complex' reservoirs.
