Type Curve Builder Package

Build production profiles for entities, aggregate them to parent level, and then calculate their cumulative.

Usage

Set-up for running the workflows in this package consists of the following steps:

1. Create a hierarchy containing the wells you wish to use for building type curves. This hierarchy can consist of any number of parent entities of the same Entity Type (e.g., "Area"), with any number of wells as children. The production data for the child wells will be used to construct the type curves, which will be stored to the respective parents.
2. Set the workspace value TypeCurveBuilderHierarchyName to the name of the hierarchy created in step 1.
3. set the workspace value TypeCurveBuilderHierarchyParentType to the Entity Type of the parent entities of the hierarchy created in step 1.

After performing the set-up steps outlined above, you should begin the package workflows by running the workflow Type Curve Builder Entity Level using the schedule provided in the package.

Details

Type Curve Builder Entity Level

Type curves for the phases oil, gas, water, and condensate are calculated and stored in reference tables for the entity on which the production and forecast data is stored.

The logic creates two distinct reference tables:

• Type Curve (Active Time): The index of the reference table represents the time steps the entity was actively producing. The entity is considered producing if data is available for at least one of the phases.
• Type Curve (Absolute Time): The index of the reference table represents the absolute time passed since the entity started producing.

Type Curve Builder Parent Level

This aggregates type curves from one hierarchy level to the parent level. The type curves for all children of the specified entity are pulled and averaged. The averaged type curve is then stored on the parent entity.

Make sure to configure the placeholders in the workflow Type Curve Builder Parent Level correctly (i.e. specify the parent or parents to aggregate the type curves to, and specify the name of the hierarchy to use. This is configured in the TypeCurveBuilderHierarchyName workspace value). To aggregate type curves for several parent entities at once, select Every Entity Of Entity Type from the drop-down and set the value accordingly.

Type Curve Builder Cumulative

This calculates the cumulative type curves for the phases oil, gas, water, and condensate both for entity and parent level.

The logic creates two distinct reference tables:

• Cumulative Type Curve (Active Time)
• Cumulative Type Curve (Absolute Time)
