Operating sequence

Inputs become a decision through controlled handoffs.

  1. Normalize the asset set

    Owner: Engineering / data
    Inputs
    Well identifiersProduction historyOwnershipOperating status

    Output: A controlled population of producing and undeveloped cases

  2. Build production forecasts

    Owner: Reservoir engineering
    Inputs
    Decline assumptionsType curvesDowntime and constraints

    Output: Forecast volumes by product and case

  3. Apply economic assumptions

    Owner: Planning / evaluation
    Inputs
    Benchmark curvesBasis and quality adjustmentsCostsTaxesCapital schedule

    Output: Monthly revenue, cost, tax, and cash-flow streams

  4. Compare and govern cases

    Owner: Management / reserves
    Inputs
    Scenario outputsRiskingClassification rules

    Output: A decision case with traceable assumptions

Failure modes to test

  1. A benchmark curve is current but the basin differential is stale.
  2. Forecast changes and economic assumptions cannot be traced to an owner or review date.
  3. A desktop or spreadsheet handoff creates two competing versions of the portfolio.
  4. A bulk run succeeds technically while silently dropping or mis-mapping cases.
