Network Pipe Constraint
The network pipe constraint table describes time-based constraints to apply to pipe elements in a network for network optimization and forecasting defaults.
Constraints will apply from the last date they were set. For example, if a record is added with date 2023-01-01T00:00:00+0000 with the "maxOilRate" variable set to 1200 STB/d, that constraint will continue to apply until a future record is added with a different value for "maxOilRate".
A NULL value for a particular constraint effectively makes that variable unconstrained. With this in mind, it is important to take care to manage constraints appropriately if various constraint variables are changing on different time horizons, as it could be easy to reset constraints unexpectedly with NULL values.
The unique constraint on the Network Pipe Constraint table rows is sourceNetworkId + sourceId + date
Variable | Data Type | Unit of Measure | Is Nullable? | Default Value | Description |
|---|---|---|---|---|---|
sourceNetworkId | String | - | No | - | Source ID of Network Header |
sourcePipeId | String | - | No | - | Source ID of Network Pipe Definition |
sourceId | String | - | No | - | Source ID for the pipe/date constraint. This sourceID enables upsert functionality from client source systems of record |
date | DateTimeOffset | - | No | - | Date at which the constraint becomes applicable. Datetime offset (with timezone) in ISO 8601 format. Example: 2022-09-27T16:28:37+0000 |
maxPressure | Double | psi | Yes | - | Maximum pressure constraint |
minPressure | Double | psi | Yes | - | Minimum pressure constraint |
maxOilRate | Double | STB/d | Yes | - | Maximum oil rate constraint |
maxGasRate | Double | Mscf/d | Yes | - | Maximum gas rate constraint |
maxWaterRate | Double | STB/d | Yes | - | Maximum water rate constraint |
maxLiquidRate | Double | STB/d | Yes | - | Maximum liquid rate constraint |
maxCFactor | Double | - | Yes | - | Maximum C-factor (pipe roughness coefficient) |
