Network Well Constraint
The network well constraint table describes time-based constraints to apply to well 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 "maxPressure" variable set to 2100 psi, that constraint will continue to apply until a future record is added with a different value for "maxPressure".
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 Well Constraint table rows is sourceId + name + date
Variable | Data Type | Unit of Measure | Is Nullable? | Default Value | Description |
sourceId | String | - | No | - | Source ID for the well/date constraint. This sourceID enables upsert functionality from client source systems of record |
name | String | - | No | - | Well name. This must match the well name in the network definition and the "Well" table |
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 |
maxDrawdown | Double | psi | Yes | - | Maximum drawdown constraint (Reservoir pressure - bottomhole pressure) |
plannedDowntime | Double | % | Yes | - | Planned downtime in percent (100% == 24 hours) |
