You can begin adding capex items through:

1. + Row: adds an empty line that you can model accordingly
   
2. + Lookup Row: adds a line where you can reference an Embedded Lookup Table (ELT). For more info on ELT, visit the "ComboCurve: Embedded Lookup Tables" article. 
   

1. Category
   
1. Capitalized investments generally access *new* prod such as moving to different zones.
   
2. Expensed investments facilitate, enhance or re-establish prod from previously completed zones.
   
3. Depletable investments are usually initial purchase of asset.
   
2. Tangible
   
1.  Tangible describes possible tax treatment such as: rigs, equipment, pipe, etc.
   
3. Intangible
   
1.  Intangible describes possible tax treatment such as: crews, employees, chemicals, supplies, etc.
   
4. Criteria Option
   
1. FPD: Begins at First Production Date
   
2. As Of: Begins at the As Of Date in Dates section
   
3. Disc Date: Begins at the discount date in Dates section
   
4. Maj Seg: Begins when major phase starts prod
   
5. Economic Limit: Begins when economic limit reached (like P&A)
   
6. Date: Begins on hardcoded date
   
7. Oil, Gas, Water or Total Fluid (Oil + Water) Rate - Rate triggers handy for workovers that occur at a certain rate.  Note that these are always monotonic and require a declining forecast.  Warning: If current rate is below the trigger, it will be treated as "already happened" and not trigger.  It must cross the given rate.
   
8. From Schedule (requires input of "Criteria From Option" - As long as you have a schedule selected for this well in the scenario page, you can refer to any of the populated dates generated from that schedule.  Null dates throw away the Investment. 
   
9.  From Headers - Pick any of the header dates to use to trigger CAPEX.  Null dates throw away the Investment.
5. Criteria From Option
   
1. This only needs to be populated when using a criteria "From Schedule" or "From Headers"
   
6. Criteria Values
   
1. Number of offset days from the referenced date in the Criteria Option
   
2. A positive number is days after the reference date
   
3. A negative number is days before the referenced date
   
7. After Econ Limit
   
1. No: the cost will not incur after economic limit 
   
2. Yes: the cost will incur after economic limit
8. Calculation
   
1. Gross values are total cost
   
2. Net is WI portion of total cost
   
9. Escalation
   
1. A dropdown here allows you to select any escalation model built in that tab to apply a particular investment in this row
   
10. Escalation Start Option
    
1.  Apply to Criteria: Begin using the escalation model at the timing selected to trigger the investment in "Criteria" (plus/minus any offset used there)
   
2. FPD: Begin using the escalation at the first production date for this well
   
3.   As Of Date: Begin using the escalation model at the current As Of date for this well
   
4.  Econ Limit: Begin using the escalation model at the Shut In  of the well (Econ Limit).  i.e. to escalate abandonment cost known at the time of shut-in to the delayed actual abandonment
   
5. Date: Begin using the escalation model at a hardcoded date
   
6. Note: none of the items above will reset the escalation but rather just begin applying it at that time.  
   
11. DD&A
    
1. A dropdown here allows you to select any depreciation depletion and amortization model built in that tab to apply a particular investment in this row
12. Paying WI / Earning WI
    
1. Multiplier of WI for carried CAPEX. Default is 1 for no carry.  This generalized multiplier can be used in a variety of ways to adjust or risk CAPEX by any fraction.
   

Drilling & Completion Cost Models

1.  $/ft TVD
   
1. $/ft multiplied by TVD to get cost of vertical portion of the well to heel
   
2. Note: you need to have the True Vertical Depth header populated
   
2. $/FT PLL
   
1. Cost per foot multiplied by the perforated lateral length to get cost for the horizontal portion of the well
   
2. Note: you need to have the Perf Lateral Length header populated
   
3. Fixed Cost
   
1. Additional cost to the $/ft amount
   
4. Unit Cost 
   
1. $/ft of perf lateral length for each scheduled proppant intensity. Used to get completion cost for well horizontal
   
2. You can add multiple rows to interpolate on Prop/PLL to get a $/ft
   
5. Tangible %
   
1. Percentage of the total cost allocated to tangible cost
   
2. 1 - % will be allocated to intangible cost
   
6. Calculation
   
1. Gross values are total cost
   
2. Net values is WI portion of the  total cost
   
7. Escalation
   
1. Dropdown to select any escalation models
   
8. DD&A
   
1. Dropdown to select any depreciation, depletion, and amortization models
   
9. Paying WI / Earning WI
   
1. Multiplier of WI for carried CAPEX. Default is 1 for no carry.  This generalized multiplier can be used in a variety of ways to adjust or risk CAPEX by any fraction.
   
10. Cost Schedule
    
1. Cost schedule begins via the trigger mechanism selected (use negative values to offset before date trigger) and set by % of cost on each row to total 100%.
   
1.  FPD: Begins at First Production Date
   
2. Disc Date: Begins at discount date
   
3. Maj Seg: Begins when major phase starts prod
   
4. Schedule Start: Begins on date of your first schedule step
   
1. You'll need to have a schedule applied in the scenario
   
5. Schedule End: Begins on the date of your last schedule step
   
1. You'll need to have a schedule applied in the scenario
   
6. Date
   
1. Begins on the hardcoded date
