From the "Projects" Tab you may open an existing project by clicking on the name on the left hand list on the page. This will take you to the Network View of the Project. You may also create a new Project from the Top "Project Menu" or Start running a New Project Wizard from the list of Wizards on the right hand side of the "Projects" Tab.

Add wells and facilities

The easiest way to add new wells and facilities is from the "Network" Tab and use the "New Well" and "New Facility" Buttons on the top of the network view. If you have an existing well you can use the "Copy Asset" button to create a complete copy of that asset along with any pipelines. New wells and facilities can also be added from the "Asset" Menu.

Connect wells and facilities (Refer to Creating a Flow Network for more detailed information)

 On the "Network" tab, select a source well or facility by left clicking on it, then on the right hand side, press the small "add" button to add a pipeline to that asset. Then use the drop down box just below the “add” button to select a target (destination) for the pipeline.

You may add more than one pipeline, and specify which products go down each line, or specify one product and set the last pipeline to use “remaining” as the product. You can specify maximum flow rates (volumetric model) , and dimensions (pressure model).

Pipelines can also be added in the "Pipeline" 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 of the network can be changed over time.  

You can refer to the Pipelines section in data entry for more detail on how pipelines work in WellSpring.


Forecasting Production

From either the "Decline/AOF" dialog or the "Decline" tab you may enter Decline (volumetric model) and Pressure data (pressure model) for your wells.   The decline you are entering is the defined  "Rate-Cum" relationship for the well, these may be curtailed by the optimizer if there are capacity or other production constraints in the network.  See also Decline and Production Forecasting

Production Constraints are entered in the "Constraints” dialog, and can include such things as maximum water rate, maximum H2S content, Maximum GOR, maximum flow volume etc.

On the "Decline" tab you have access to a fully capable graphical production forecasting system, including best fit to historic production and manual adjustment. Please see the Decline section of the help for more information on using the Graphical decline functionality.

Enter Capital and Operating Costs (See Capital Expenditure and Operating Costs)

Economic input data such as Capital, Operating Costs, Processing Fees, are all entered in the data Dialogs specific to each type of input.  All input data associated with specific Assets, so you must select an asset before entering the data dialogs.

You can view all of the data for the current asset at one time by going to the Data tab.   From here each specific type of data can be edited by selecting the edit link on the side of the data. Use the "Add Opcost" or "Add Capital" buttons to create another row in the tables.

Economic data is always entered in “Real” terms, and then escalated at the rates specified in the Escalation Set which is selected in the "Project Data" dialog.  This is accessed by clicking on the project name at the top right of the main screen.

Enter Company Interest  and Reversion data (See Land)

Land data is entered in the “Land” dialog. By default all assets inherit their land data from the project. This means that if all of your assets share a common working interest etc, you may click the "goto linked asset" and edit the land data at the project level for all of your assets.

Land Reversions may be either active for each individual asset or act as a group with respect to reversions. This enables modeling of block level or ring fence reversions.

Calculate economics and see the results (See Calculations)

Press the "Calculate" button just below the menu at the top of the screen.

Press "Ctrl-S" to view a project summary report at any point. Other results may be viewed on the "Report" tab, on the "Graphs" Tab, or on the bottom of the "PlanView" tab.   

Right clicking on any asset in the Network view will bring up the selected report or graph.  Select this report in the drop down on the bottom right corner of the Network Tab

Other calculation options are available from the "Calculate" menu and the "Pressure" menu when running the pressure model. It is a great idea to use the "Pressure ---> Run First Step Only" menu item  to tune a complex pipeline pressure model for history matching before calculating all of the timesteps.

Graphically change the production start date for my wells (See Planview - Working with Scenarios)

From the "PlanView" tab, you may drag and drop the wells and facilities. This will change the well's start date as well as shift any attached Capital or Operating Costs that have not be designated as "Fixed Date".

There is a check box at the top of the "PlanView" tab that indicates whether you want the project results to be automatically re-calculated after each drag and drop operation.

Loading Production history data for wells on the decline tab

 Customers may import a ".AXP" export file in the "Merak" production history format from the "Projects" tab. On the right of the screen clicking on the "Import Production Data" will start the process.  From the "Decline" tab, a user may link a well to an existing well by pressing the "Select Well" button.

See the “Production History” page under the “Decline and Production Forecasting” page of this help system for more details.
