*Buoyancy factor is used to compensate for loss of weight when steel tubulars are immersed in fluid.Applicable only when tubing or casing is completely filled with fluid.Actual hook load = length of string (ft) x weight of string (lb/ft) x Buoyancy Factor.

Tubing Movement FormulasChanges in temperature and pressure cause contraction orexpansion of a tubing string as covered in detail in the BakerPacker Calculation Handbook. For ready reference, theformulas for calculating the forces developed by this contrac-tion/expansion are given below:

F1 (piston effect) = (A p - A i) Pi - (A p - A o) P oF2 (buckling effect) = usually negligibleF

3(ballooning effect) = .6 ( P

iaA

i- P

oaA

o)

F4 (temperature effect) = 207 A s t

The above forces are in pounds and the equivalent tubingmovement can be obtained from the stretch charts in anothersection of this handbook or can be calculated using the formula

L (stretch or contraction in feet) = F x LE x As

where F = force in pounds

L = tubing length in feetE = elasticity factor of steel = 30,000,000

A s = cross section area of tubing in sq. inches

Terms used in the force formulas are defined below:A s = cross section area of tubing in square

inches = A o - A iA p = area of packer bore in square inches

A o = area of tubing OD in square inches

A i = area of tubing ID in square inchesP i = change in tubing pressure at packer in pounds

per square inchP o = change in annulus pressure at packer in pounds

per square inchP ia = change in average tubing pressure in pounds

per square inch
