Field Description Tubing ID (in) Tubing inner diameter Grade Tubing material grade (e.g., L80)
Field Description Reservoir Temp (°F) Bottomhole temperature Producing Wellhead Temp (°F) Wellhead temperature while producing Static Wellhead Temp (°F) Wellhead temperature when shut-in
Field Description Pump Depth (MD-ft) Measured depth to pump
Field Description On Production Casing Pressure (psi) Casing pressure while producing On Production Tubing Pressure (psi) Tubing pressure while producing
Field Description Overpull Required at Surface (in) Target tubing stretch Additional Load for Pump on Tap Case (lbs) Extra load allowance Desired Tension at Anchor (lbs) Target tension at anchor
Output Description Surface Pull Required (lbs) Total pull needed at surface Expected RIH String Weight in Water (lbs) String weight during run-in Loss of Tension due to Thermal Exp. (lbs) Tension loss from heating Loss of Tension due to Piston Effect (lbs) Tension loss from pressure differential Gain in Tension due to Ballooning (lbs) Tension gain from pressure effects Additional Tension Required (lbs) Net additional tension needed Required Tension on Tubing Hanger (lbs) Final hanger tension
Visual gauge showing the calculated surface pull with class rating indicators (Class I/II through Class V).
Determine proper tubing hanger tension
Prevent tubing unseating during thermal cycles
Account for pressure-induced forces
Ensure adequate tension for anchor engagement
