Edit Network Topology

navigation once you save a new network or open an existing network from the dashboard, you will automatically be redirected to the network editor there are 5 main elements in the network editor breadcrumb the breadcrumb at the top of the page shows the active group and network clicking on the xecta logo (x icon) will navigate back to the landing page equipment list as you add equipment to the network, it will appear in this list, which has search and filter functionality clicking on an equipment will zoom and focus the editor to that equipment design canvas equipment is placed, organized, and connected on the canvas toolbar the toolbar contains a selection tool, equipment creation tools, a zoom tool, and undo/redo tools hovering over an icon will spawn a tooltip describing that tool settings panel by default, you will see network level settings when no equipment is selected when equipment is selected, the content of this panel will change to be specific to the selected equipment adding equipment equipment can be added by selecting a specific tool from the toolbar and clicking on the canvas to drop that equipment injection networks have the following tools available well, pipe/edge, joint, and compressor any equipment additions, deletions, or location changes are saved automatically add a compressor in this example, we're creating a gas lift injection network the first step is adding a compressor click on the compressor icon in the toolbar and place the compressor on the design canvas after placing the compressor, switch back to the selection tool and select the newly added compressor adjust compressor settings once selected, the settings panel on the right changes to display injection compressor specific content here you can change the name and add any known constraints in reality, the only compressor specific contraint is the max gas lift injection rate; however, to facilitate ease of use, system level injection system constraints are also specified in the start node compressor for injection networks these include max oil rate, max gas rate, max water rate, and max liquid rate for this example, we're going to rename the compressor to "centralized injection compressor" and set a max gas lift injection rate of 4000 mscf/d click "save" to submit your changes add wells next, we will add wells by default, only prodx wells can be added select the well tool and click on the design canvas to bring up the well selection list the well selection list is the same hierarchial well selection tool found in prodx that allows groups, filtering, and searching you can add multiple wells at a time in this example, we will select all wells in the "storm cf2" central facility click "add wells" to place them on the canvas adjust well settings then, if you switch back to the selection tool and pick any one of the wells, you will see the settings panel on the right update with well specific settings wells linked to prodx have a read only name, but the link to prodx can be adjusted as needed optimization mode allows you to select whether the well is "fixed" or "optimize" (default is optimize) for gas lift injection networks, fixed would indicate the optimizer cannot modify the injection rate of the well optimize would allow the optimizer to adjust the injection rate of the well constraints allows you to set any well level constraints the optimizer should respect the min and max gas lift injection rates will be pulled from prodx gas lift performance settings when a scenario is ran (and are not shown in this form) when reconciling final min/max gas lift injection rate constraints the minimum of this form's max injection rate and the prodx max injection rate and the maximum of this form's min injection rate and the prodx min injection rate are selected oil, water, gas, and liquid constraints only populate from this form add joints network nodes (wells, separators, compressors, etc) only support one connection joints allow multiple connections to be made in this example, we're going to simulate two pads of wells connected to a single compressor to accomplish this, we will create one joint per pad and one central joint to connect both pads to the compressor first, add two joints to the network above the wells like this we can then select these joints and give them a meaningful name in this example we'll use "pad 1" and "pad 2" we can also create the third joint to connect the pads to the compressor we'll call that one "compressor joint" add edges and pipes now that our joints are placed, we can switch to the "pipe/edge" tool to start connecting equipment in this example, the direction of connection is important gas flows from the compressor to the wells first, select the "pipe/edge" tool from the toolbar, then click on the compressor, which will trigger the connection to start click again on the "compressor joint" to end the connection repeat the process twice more to connect the "compressor joint" to "pad 1" and "pad 2" note when connecting a joint to another joint, a pipe will be created instead of an edge in the case of injection networks and specifically a "multi well gas lift" scenario in this example, the pipe is purely representative the pressure drop will not be considered however, for simulation, calibration, and optimization scenario types, pressure drops across pipes will be computed finally, connect each pad to its respective wells following the same process at this point, the network has been completely designed and is ready to be imported into a scenario deleting equipment if you need to delete any equipment, you can click the purple " " icon to the right of the equipment on the canvas moving equipment to move any equipment in the network, use the selection tool to select the item (a purple dashed box will appear around it) then you can click and drag to place the item in an alternate location
