Defining wells for simulation input

The Wells form (simulate > IMEX or GEM or STARS > Wells) is used to create, modify and connect well data and tubing tables for the simulation input.

The following options and settings are available on the Wells Form, Panel 1

1. The Wells view can be opened by clicking the Edit wells button. This view displays the well data for the current simulation case, which can be reviewed and modified as needed.

2. Optionally, you can connect historical production or injection data to the wellbores assigned to your simulation case.

   Production data set (PDS)  Selects the observed production data set (PDS) to be used.

   Link columns  Use this table to map the column names from the Wells View > Wells tab, to the corresponding property names defined in the production data set (PDS) file. You can also define a filter for this mapping. For example, you can enter the name used in the PDS file for WHP or BHP, and it will be automatically detected.

   Connect production data  Creates connections between wellbore perforations and the historical production or injection data.

3. Update wells from model

   View wellbores  Opens the Well Table for editing.

   Update from model  For each connected well, updates the tables on the Perforations tab and the Well Constraints tab.

4. Edit or import lift tables

   Edit tables  Opens the Production Well Tables / Injection Well Tables view. Inspect data and edit if necessary.

   Import tables  Click Import tables to open the data selection import window.

5. Edit well groups If you wish to create well groups and assign the wells in your simulation case to specific well groups, you can follow the steps below:

   1. Make sure you have selected the correct simulation case on the Simulation case form.
   2. On the Wells form, click on the Edit groups button under the Edit well groups section. This opens the Well Group table in the simulation view.
   3. In the Well Group tab, create a new well group by specifying the group name, associated parent group and the date/time when the group is defined. Check box in the active column to indicate if the group is active. You can specify the group configuration, constraints and group cycling rules in the subsequent adjacent tabs.
   4. To assign the wells to a well group, open the Wells view. In the Wells tab, select the well group from the drop down in the WellGroup column.

More functionality is available by clicking the Next – Wells (2/2) shortcut at the bottom of the form.

The following options and settings are available on the Wells Form, Panel 2

The second form of the Wells functionality is used to create or modify tubing tables. Note that each step in this panel is optional; the simulation will run without any further data specified here.

1. The black oil correlation may be defined in this table. By right-clicking in the table you are able to choose the units and format you want displayed. Each of the fluid types is described in the sections below.

2. Well geometry must be defined for the THP correlations, if the PVT correlation is defined.

   Well Path  Selects a wellbore from the static model.

   Reference depth  Depth of the wellbore to be used in the THP calculations.

   Diameter  Diameter of the wellbore to be used in THP calculations.

   Roughness  Pipe wall roughness of the wellbore to be used in the THP calculations.

3. In the THP table, tubing head pressure or lift table correlations can be used to create deck sections. Three types of THP tables can be produced: Oil Producer, Gas Producer and Injector. The 'Table Type' parameter of the table indicates which type of table to produce. The Production Well Table will look different depending on which table type is selected. See the section Using the THP table for further information.

4. A tubing table can be created from THP correlations or open the tubing table view for editing.

   Create table(s)  Use parameters defined in steps 1-3 to create a THP table.

   Edit table(s)  Opens the Tubing Table view for editing.
