Burst loads 1. Burst during drilling
Burst loads can occur during the drilling phase due to displacement of the borehole to hydrocarbons. There are, however, a number of special cases to be considered. The base case and the special cases will be addressed in this section.
1.1 Internal pressure profile
The worst-case internal pressure loading is that following a complete loss of primary control corresponding to full displacement of the casing to gas and the well closed-in at surface. The internal pressure profile is based on a gas gradient taken from the pore pressure . . .
