Detailed Design and Analysis
In the detailed design phase, the casing designer determines the material grade and casing wall thickness for each section of the casing scheme selected, which will allow it to withstand all realistically expected loads throughout the life of the well.
Selection of relevant load cases
Before design calculations can be performed for a given casing section, the casing designer must decide which load cases can realistically be expected to occur.
The design loads for the load cases selected are determined and compared with the resistances to burst or collapse . . .
