¶ WCD Collapse Level 1
This load evaluates the collapse load during uncontrolled flow to seafloor. Temperature and pressure assumptions for this load are:
- Internal pressure - seawater hydrostatic at the mudline casing hanger seal, hydrocarbon gradient below to the depth of interest
- External pressure - fracture gradient at the prior casing shoe (1) plus original mud hydrostatic to the Hydraulic Isolation Depth (HID), pore pressure below HID and (2) minus original mud hydrostatic above prior casing shoe.
- Temperature - a choice of Undisturbed Temperature, Influx Temperature, or a thermal simulation temperature profile.
The form provides an input field for influx depth. This is the depth at which the influx temperature will be calculated, based on the Undisturbed Temperature data.
