DESIGNED FOR

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 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

ABOUT THE COURSE

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)
