Course Description

  This course provides an overview of how to conduct SCAL studies from practical point of view. On the other hand, how to follow-up SCAL study done by laboratories. The course emphasizes the practical aspects of reviewing SCAL reports and how to identify reliable SCAL data, how to prepare SCAL program, how to QC laboratory measurements and refine SCAL data to be used in simulation studies.

Course Objectives

  • Learning about how to review SCAL studies and identify reliable SCAL data
  • Understanding how to collect and preserve core to conduct SCAL study
  • Learning about the preparation of SCAL program for new SCAL study
  • Understanding how to QC laboratory SCAL measurements
  • Gaining insights into  refining SCAL measurements before using the data in dynamic     

Who Should Attend?

  • Reservoir Engineer who are following/involving in special core analysis laboratory (SCAL) studies
  • Reservoir geologist and engineers who is interested in how to prepare and review SCAL program
  • Reservoir simulation engineers who are following/involving in special core analysis laboratory (SCAL) studies
