While the primary objective of the course is to prepare reservoir engineers and/or geologists to validate and use existing results, it will be invaluable to those faced with the responsibility of formulating a special core analysis programme for a new well or field.

The potential savings in avoiding expensive programmes yielding unreliable or questionable results are significant.
