Essential Wireline Formulas

Hydrostatic Pressure (HP)
HP = 0.052 × MW × TVD
HP = 0 psi
Pressure Gradient (PG)
PG = 0.052 × MW
PG = 0 psi/ft
Formation Temperature
Tf = Tsurf + (Gt * Depth)
Tf = 0 °F
Buoyancy Factor (BF)
BF = 1 - (MW / 65.5)
BF = 0
Cable Stretch (Rochester)
ΔL = (W × L × K) / 1000
Stretch (ΔL) = 0 ft
Pipe Capacity
Cap = ID² / 1029.4
Cap = 0 bbl/ft
Free Point Constant
FPC = (As × 2500) / W_pipe
FPC = 0
Annular Volume
Vol = (IDh² - ODp²) / 1029.4
Vol = 0 bbl/ft
