Economics - Capital Expenditure Package

Allocate capital expenses for wells based on a capital expense schedule.

Usage and Configuration

To perform the calculations run the workflows from this package starting with the workflow Economics - Capital Expenditure. The schedules may be adapted to use different contexts.

Follow the steps given in How do I configure packages pulled from Datagration's package repository to change the configuration of the package.

Use the workspace values EconomicsEffectiveDate and EconomicsAnalysisMonths to specify the start and the duration of the scope Economics. This scope will be used during the calculations.

Use the workspace value EconomicsHierarchyName to define which hierarchy to use during the calculations. Make sure this hierarchy exists and contains all wellscapital expenses shall be calculated for.

Use the workspace value EconomicsParentEntityType to define the entity type of the parents used for retrieving input values to well level.

If needed, set a yearly inflation rate using the workspace value YearlyInflationRate.

Preparations

  • Input all required static signals for parent- and child-entities using the data views Economics - Capital Expenditure (Parent) and Economics - Capital Expenditure (Child). These data views store the information in the scenario Economics - Capital Expenditure Base by default.
  • Define capital expenditure schedules per economic well type and scenario using the reference table Capital Expense Schedule. If no schedules are provided, the entire capital will be expended at the first time step of the used scope

Details

Workflow Economics - Capital Expenditure Delete Reference Table Data

This step deletes existing data in the reference table Allocated Capital Expenses. This table is used to store the calculated operating expenses for each processed entity and scenario.

Workflow Economics - Capital Expenditure

The P# script used in this workflow allocates capital expenses for wells based on the Capital Expense Schedule reference tables of their parents and saves the results to the Allocated Capital Expenses reference table.

Data Requirements

The following data is required on parent level:

capital expense factor
start of production offset for development wells
start of production offset for evaluation wells
start of production offset for rework wells

The following data is required on child level:

economics well type
capital cost
date of first production
