Types of CasingTypes of Casing

Conductor Isolation, shallow gas protection, structural support. Surface Isolation of ground water, pressure control, build section coverage. Intermediate Borehole stability, isolation of low pressure or producing zones. Production Isolate producing zone, tubing leak protection, injection, gas lift. Liners Local isolation and protection. Tiebacks Convert liners to full strings to the wellhead.

Not all strings see loads during entire service lifeNot all strings see loads during entire service life--drilling and intermediate stringsdrilling and intermediate strings

Production strings are primary pressure vesselsProduction strings are primary pressure vessels

Principal Load TypesPrincipal Load Types

Load Type Cause Axial tension / compression

Running, changes in temperature, slack off or pickup after cementing.

Pressure Burst or collapse due to kick, pressure test, shut in, cementing, injection, circulation, evacuation, etc.

Bending Axial load due to buckling or doglegs. Torsion and shear

Normally not considered in casing design unless the liner will be rotated while cementing, for example.

Loads always occur in combination!Loads always occur in combination!
