Pipelines

To add a pipeline to your network, select a source well or facility by clicking on it. On the right hand side of the screen, press the small 'Add' button to add a pipeline to that asset. When you press the 'Add' button, the pipeline will initially be dangling (it is actually flowing to the Scenario). Use the drop down box just below the 'Add' button to select where the pipeline flows to complete the connection.

If you have not named your new facility, it will still be listed as 'New Facility'.

Split Flow

Split flows are created by adding extra pipeline connections in-between wells or facilities. They can be input into the system either by importing a CSV load files or by manually adding the split node in the system. To manually add the split node in the system, simply select the upstream asset and click 'Split' for the desired pipeline.

Advanced Pipe Addition

Pipelines can also be added from the Pipeline Connections dialog accessible from the Data tab, the Data menu, or the Network Tab. A pipeline can be assigned a start and end date so that the construction of the network can be changed over time.

Selecting Pipeline from the Network tab provides a detailed data entry screen as below:

Effective Date

On this screen the effective date of the pipeline can be added (start and end date). These dates are used to model future pipelines that will be constructed. The dates can be either Absolute, or they can move with the upstream project. Typically they will be absolute dates. Enersight displays future pipelines with a dotted line.

An asset with a future pipeline will still "flow" to the scenario by default. If you have a future pipeline, you must also put an initial constraint of zero to ensure that the asset does not flow prior to the pipeline connection. See Constraints for more information on constraints.

Product Stream

The product stream specifies which products are sent down this pipeline. To add multiple products, use multiple pipelines. You can also set it up to flow oil down one pipeline and everything else down another pipeline using the "REMAIN" function.

Flows To Target

This is used to connect the upstream asset to the downstream asset. Select the upstream facility then flow the pipeline to the downstream facility.

Maximum Split Percentage

Often times you will want one product to flow to two or more different targets. This can easily be done by assigning a Maximum Split Percentage to a pipeline that divides the total product flow into parts. The Maximum Split Percentage of multiple pipelines should sum to 100.

Maximum Daily Rate

The allowable capacity of the pipeline can be specified here. Constraints can also be put in at the facility level via the "Constraints" menu item. Putting a maximum flow rate of 20,000 mcf/day will curtail any production above that until the limit is reached.

We recommend that any constraints be entered via facilities to be easily managed and reported. If you have a constraint on a pipeline, simply create a facility to represent that pipeline. See Constraints for more information on entering constraints for facilities.

Priority

Where there is more than one flow path for a stream, pipeline priorities can be established. 1 is the highest priority, while 10 is the lowest. There are 10 levels only to provide enough resolution to prioritize should you have many pipelines. For example, consider a flow of 150 mmcf/day through a plant that has two sales points. Pipeline A produces to a contract of 100 mmcf/day, and Pipeline B flows to a spot market, then setting pipeline A's priority to 1, and B's to 2 would result in a flow of 100 mmcf/day to A, with 50 mmcf/day to B.
