Casing landing practice is concerned with the transferral of casing weight to the well head or casing hanger after cementing. The operator is primarily interested in obtaining maximum protection and performance from API casing in overcoming the various active stresses that are present during completion and future production of the well. These stresses consist primarily of tension, collapse, burst and longitudinaal compression. Casing is design to withstand three principal mechanical forces, viz., internal pressure, external pressure, and longitudinal or axial tensions.
- General landing practices
- Landing in tension at the freeze point
- Unstressed landing at the freeze point
- Landing in compression at thee freeze point
- Buckling criteria
- Wellhead loads
