Enhancement Tracking

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:

$IOR=V2\ - V1\ - V3$

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 .

Workflow

1. Upload required data
2. Completions check
3. Group Reservoirs to Objects if needed
4. Review the Performance Plots
   1. History Plot
   2. Cumulative Production Plots
   3. Reciprocal Rate Method Plot
   4. WOR vs Np Plot
   5. VRR Plot
   6. VRRcum Plot
   7. P/Z plot
5. Identify Reservoirs / Objects with performance gaps
6. Apply the Mature Water Flood Analysis if needed
7. Identify the actions required to enhance Reservoirs / Objects production and recovery
8. Calculate the Reservoirs / Objects production and recovery forecasts
9. Execute
