The IPR tab contains the following elements:

• Open inflow model editor (  ) – inflow model editor. To make changes to the selected model;
• Reservoir pressure correlation – well reservoir pressure correction relative to the weighted-average reservoir pressure;
• Main inflow model parameters in the upper part of the tab.
• Plot of bottomhole pressure versus liquid flow rate in the lower part of the tab.

The inflow model editor has 4 areas.

The control panel contains the following elements:

• Name of the selected completion;
• Match pressures – automated matching of reservoir pressure to well test data;
• Match coefficients – automated matching of the productivity coefficient to well test data.

Input parameters contain the following fields:

• IPR type – drop-down list. The following types are available: for oil wells – Vogel, No flow boundaries, Transverse vertical fractures; for gas wells – Forchheimer, C and N, Forchheimer with pseudo pressure. The set of parameters differs for each type;
• set of input parameters depending on the selected IPR type.

The "Well test data" area contains the following elements.

– Add. Adding new rows for entering data;

– Delete. Deleting the selected row;

– copy to clipboard. Used to copy and save data in external tables;

– paste from clipboard. Used to paste values from external tables. For correct paste, select the required cell in the table; the entire copied value range is pasted starting from the selected cell.

The table contains the following data:

• liquid flow rate. You can paste a single value from the clipboard, type it from the keyboard, or set the value using the spinner in the cell while editing;
• bottomhole pressure. You can paste a single value from the clipboard, type it from the keyboard, or set the value using the spinner in the cell while editing.
