More than three-quarters of current additions to the world's reserves come from better management of existing reserves. Core-based measurements offer the most tangible and direct means of determining critical reservoir parameters. Core analysis can play a vital role in field equity or unitization and is often considered to be the ground truth to which other measurements are compared, e.g. wireline logging. Using a multidisciplinary approach, participants are taken through the steps necessary to obtain reliable core analysis data and solve formation evaluation problems. Throughout the course, participants are given hands-on problems and practical laboratory and field examples, which reinforce the instruction. * Laboratory visit with core analysis measurement demos (where feasible).

Reservoir engineers, exploration and development geologists, core and log analysts, geophysicists, drilling and completion engineers, and oil company research and development staff.

You will Learn:

Participants will learn how to:

  • Design coring programs and maximize recovery
  • Preserve core to minimize rock alteration
  • Take and analyze sidewall cores
  • Use cores to estimate porosity, permeability, and fluid saturation (basic core analysis)
  • Understand special core analysis, e.g., wettabililty, relative permeability, capillary pressure, and reservoir fluid distribution for reservoir engineering and petrophysical evaluation
  • Prevent/spot errors in core analysis vendor reports (quality control)
  • Select samples for special core studies
  • Correlate core and log data
