Date Triggers:

1. Flat: From As Of Date to Econ Limit
2. FPD : Begins at First Production Date
3. As Of : Begins at As Of Date applied in Dates section
4. Maj Seg : Begins when main phase starts prod
5. End Hist : Begins when well switches from actual historical data to forecasted data
6. Dates : Begins on scheduled date
7. Oil, Gas or Water Rate: Begins when prod crosses the threshold set for that one product.
8. Only “Gross Well Head” can be selected in this tab.
9. Monotonic or Non-Monotonic, is how variable production is treated with former not allowing rate changes on subsequent threshold crossings
10. Monotonic: Only decreases trigger changes. If forecast increases, no changes will be made to the value.
11. Non-Monotonic: The values look back up the schedule and vary with prod, up or down.
    

1. NGL Yield coincides with Gas Shrink since volume reduction occurs in the gas due to removal of the NGL.  The yield can be represented in one of two ways:
2. Unshrunk Gas (default): This is the measured BBL of NGL divided by the Produced Wellhead Gas.
3. Shrunk Gas: This is the measured BBL of NGL divided by the Gas sold .
   

Drip Condensate

1. Oil Shrink is % volume fluid remaining caused by reduction in temperature and by the liberation of light ends as pressure is decreased.  Distinct from any oil losses occurring through other means.  This deduction affects only “Oil” and not “Drip Condensate”.
2. Gas Shrink coincides with NGL Yield since gas volume reduction is due to NGL removal. Usually calculated by sales gas divided by the wellhead gas produced (thus, % remaining, not % lost) at some aligned interval not including gas loss or flaring. If loss or flaring is transitory or measured separately, it should be reflected in the Loss/Flare Section.

1. Oil Loss - Volume % remaining after losses by anything other than normal shrinkage.  This reduction affects only “Oil” and not “Drip Condensate”.

BTU Content

1. Unshrunk Gas (Wet Gas) impacts only variable expense
2. Shrunk Gas (Residue Gas) impacts revenues and possibly expenses depending on dropdown selectio

Custom Stream Properties

1. Users can define set a % remaining for any indicated company/project level custom stream to adjust Gross Wellhead Volumes to Gross Sales Volumes
   
2. From the Stream Properties assumption's Advanced View, all created custom streams will be displayed under the 'Key' dropdown
   
1. Custom stream stream property settings cannot be defined from standard view.
3. After selecting a custom stream in the 'Key' cell, make sure to indicate:
   
1. The stream type (Company/Project Custom Stream) in the 'Category' column
   
1. Deductions cannot be broken out into different categories (ie shrink vs. loss) like default streams can
2. The criteria (flat, time series, or relative time from your effective date) and corresponding period
