Brief
Enhancement Tracking is a workflow to track and evaluate the benefits of executed Enhancements.
As a result Enhancement Tracking provides a Scorpion Plot which answers those questions:
- How much was spend on each campaign?
- What is the incremental oil recovery for each well and campaign total vs plan?
- Which campaign has better $/bbl performance?
- Which enhancement has better $/bbl performance?
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) well 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].
