Custom Load (Tube)
Custom Load has tabs you use to specify density, pressure, and temperature profiles inside and outside the current string that are not available from any of the standard load types. Use the String tab to specify profiles inside the string and the Annulus tab to specify profiles outside.
On the String tab, the Tubing Profile group box, located on the left, is used to define tubing density or tubing pressure profiles. On the Annulus tab, it is the Annulus Profile group box, and it is used to define annulus density or annulus pressure profiles.
The Tubing and Annulus Temperature Profile group boxes are defaulted to undisturbed temperatures. Enter the temperature profile your want to model as final temperature for this load. Entries are assumed linear between the entered depths, and values should be entered at the top and base of the string.
Fracture Screen-Out
This load case models the high injection pressure encountered at the end of a fracture operation. The prior load case (usually an injection case) is recalled for temperatures, internal densities, and external conditions (such as casing pressure).
Fields and Controls
Pump Pressure
Pressure applied at the wellhead.
Operation or Load
This drop-down list box has the names of all loads or operations defined for the current string that can be linked to other loads. Selecting one of these items allows the code to use the temperature profile from the item as final temperature conditions for the current load case.
