Brief
Enhancement Tracking is a workflow to track and evaluate the benefits of the Enhancements.
As a result Enhancement Tracking provides a Scorpion Plot which is $/bbl metrics of the Enhancements.
Math and Physics
The incremental oil recovery (IOR) for the given Enhancement is:
where:
- V2 - production increase due to Enhancement,
- V1 - production loss due to downtime,
- V3 - production loss due to decline rate.
IOR is calculated to selected Enhancement lifetime or economic limit.
Decline Curves are used to model base (before) and enhanced (after) decline rates.
Scorpion Plot
The Scorpion plot graphically illustrates total program split by individual events and ranked by success. The curve initiates from the origin at a low scope (low $/bbl) and increasing until running to a vertical asymptote (money spent with no gain in production) and possibly even a negative portion (money spent and production lost as a result of the intervention). This effectively displays program performance ($/bbl), total volume, total cost, and success rate [1].
