Deterministic  vs.  Probabilistic planning method

Clearer overview of well costs’ division gives a higher level of confidence for the investment decision to be made by the management.

The ability to show the management that the calculated well costs are based on realistic operations and prices for services is essential.

There is some confusion as to what the difference is between probabilistic and deterministic planning.

The normal deterministic approach allows for only one course of events. This approach makes it very hard to address all of the possibilities that may arise during an operation.

Using probabilistic planning based on a simple spreadsheet offers benefits of ranges for time and cost, it is, however, difficult to enter information on the different paths.

By applying AGR’s P1™ software, the drilling teams are able to achieve a comprehensive understanding of the time-cost risk spread in well projects.

This can help provide detailed answers to the three basic questions in managing well investment decisions:

– What is the likelihood of overrunning the budget? – What is the level of exposure associated with any overrun that may occur? – Where do the individual risks lie?
