Casing Design Loads
Introduction to Casing Design Loads (Collapse, Burst and tension Load)
1 Collapse Load
The design load case for collapse is based on a partial evacuation of the casing string.
For partial evacuation during the drilling phase, the internal pressure profile is based on mud losses to pore pressure. Full evacuation after a blow-out is evaluated as a special case.
For the production casing with gas lift facilities, full evacuation above the packer . . .
