Casing scheme selection
The output of this process is a preliminary well configuration specifying the minimum casing diameter and the minimum casing-shoe setting depth for all strings. This serves as input for the detailed design phase.
- The casing diameter is mainly determined by the availability of downhole drilling equipment, logging tools and production requirements. The casing-shoe setting depth is usually a function of the strength of the formation to be drilled through and the wellbore loading during the drilling operation.
- Selection of the optimum (most cost-effective) casing scheme for the anticipated . . .
