1 FOOTNOTES TO COILED TUBING SPECIFICATION TABLES Specified Diameters (D) and Wall Thicknesses (t) are specified by Quality Tubing NOV. Many specified diameters and wall thicknesses appear in the API Recommended Practice RP 5C7 (Recommended Practice for Coiled Tubing Operations in Oil and Gas Well Services). Minimum Wall Thickness (tmin) in Un-repaired Sections of coiled tubing workstrings, is equal to the specified wall thickness minus 0.005 inches for all sizes and thicknesses.

tmin = t - 0.005 inches Minimum Wall Thickness in Repaired Sections of strings does not fall outside the minimum wall specified by the customer unless the customer so approves. For Hang-Off Strings, the minimum wall thickness is 87.5% of the specified wall thickness.

tmin = 87.5% t This may occur at flaw-removal areas. Calculated Inside Diameters (d) are equal to the specified outside diameter (D), minus twice the specified wall thickness.

d = D - (2 x t)

Theoretical Plain End Mass in US Customary units is based on specified dimensions of coiled tubing and calculated with the following formula:

mpe = 10.69 x (D - t) x t (lb/ft)

Pipe Body Yield Load and Tensile Load for new coiled tubulars are based on specified outside diameter, specified wall thickness and either the minimum specified yield strength or tensile strength as appropriate. The values are rounded to the nearest 10 pounds, in accordance with API practice, or to the nearest 10 kg. Caution is advised when working with worn strings, because both the yield load and tensile strengths may diminish. Calculated Internal Yield Pressure and Hydrostatic Test Pressure for coiled tubing workstrings are based on specified minimum wall thickness (tmin), specified minimum yield strength, specified outside diameter and the Barlow formula. The internal yield pressure is rounded to the nearest 10 psi, in accordance with API practice, or to the nearest 0.1 MPa. The hydrostatic test pressure is rounded to the nearest 100 psi, in accordance with API practice, or to the nearest 0.1 MPa.


www.nov.com

Hydrostatic Test Pressure for New Tubing is defined as the minimum test pressure (80% of the yield pressure) for a string, calculated from the Barlow formula and using the thinnest wall section in the string. Mechanical Data Common to all Grades: Flow Areas, Internal Capacities, External Displacement, Free Point data, and the external minus internal displacement, using specified values for coiled tubing, and without allowance for the presence of internal flash. Internal Flash: Flash does not exceed the wall thickness or 0.090-in whichever is smaller. This should be borne in mind when running gauge balls. Cautionary Notes 1. The performance properties and test pressures shown apply to as-manufactured coiled

tubing and do not take in to account additional deformation, axial load, residual stresses or ovality caused by spooling or service cycling. The Collapse Pressure Section of the Technical Resource Manual provides details of the effects of tensile loading, torsion, ovality, and suggested corrosion derating factors on the collapse pressure for used coiled tubing.

2. Quality Tubing NOV recommends that working pressure and working loads should be based on appropriate safety factors. It is not the responsibility of Quality Tubing NOV to determine operating safety factors. The hydrostatic test pressure is internally specified, and should not be considered as a working pressure.

3. Quality Tubing NOV advises its customers that the Yield Strength of any coiled tubing product may be slightly reduced over the first few cycles of use.

2 COMMONLY USED COILED TUBING ENGINEERING DEFINITIONS Specified Outer Diameter (D) The outer diameter as specified in this publication. This quantity is reported to 0.001-in. The tolerance on the specified outer diameter is 0.010-in. for new coiled tubing. Measured Diameter (Dmeas) The outer diameter as measured with a calliper. This quantity is also reported to 0.001-in. It is measured and recorded for the tensile test samples, and during any NDE prove-up. Specified Wall Thickness (t) The wall thickness as specified in this publication. In the case of True-Tapered sections, the specified wall thickness at a location in the tapered section may be taken as the average of four (4) equally-spaced wall thickness readings taken with a suitably calibrated compression wave ultrasonic unit at the same axial location, but not including readings taken on the flash line. These quantities are reported to 0.001-in. Measured Wall Thickness (tmeas) The wall thickness at a specific location, as measured by micrometer or suitably calibrated compression wave ultrasonic gauge. This quantity is reported to 0.001-in. It is measured and recorded for tensile test samples, and during any NDE prove-up. Calculated Inside Diameter (d) The calculated inside diameter is the value calculated from

d = D - 2 x t

The measured inside diameter (dmeas) may be different from the calculated value because of inside flash, slight ovality, and neither the measured outer diameter (Dmeas) nor the measured wall thickness (tmeas) being identical with the specified values.


www.nov.com

Minimum Wall Thickness (Coiled Tubing tmin) The minimum permitted wall thickness during the manufacture of a new coiled tubing string is t - 0.005 in. (t - 0.13 mm) at all locations including welds. This arises because of engineering tolerances. For wall thicknesses in excess of 0.110-in, this is tighter than the tolerance stated in API RP 5C7. The measured wall thickness of in-service strings may be less than tmin due to wear, abrasion, corrosion, etc. Quality Tubing will consider removing an imperfection up to, but not exceeding a remaining wall of 87.5%. If such an imperfection is removed a non-conformance report is generated. Minimum Wall Thickness - Hang Off and Line Pipe The minimum wall thickness of downhole hang off and coiled line pipe strings is 87.5% of t, unless otherwise specified by the customer. Pipe Metal Cross-Sectional Area (A) The pipe metal cross-sectional area (A) is calculated from

A = x (D t) x t and is given to 3 decimal places. This formula does not include the effect of internal flash, when present. Plain End Mass per Unit Length (mpe) The mass per unit length is calculated from

mpe = 10.69 x (D t) x t and given to 3 decimal places. This formula does not cover the presence of internal flash. Earlier catalogues used 10.68 instead of 10.69. Tables published by others may give the result to 2 decimal places.


www.nov.com

Pipe Body Yield Load and Tensile Load The Pipe Body Yield Load (Ly) is the axial tension load (in the absence of pressures or torque) which produces a stress in the tube equal to the specified minimum yield strength (SMYS) in tension:

Ly = x (D - t) x t x SMYS Where: SMYS = Specified Minimum Yield Strength D = Specified Outside Diameter (in.) t = Specified Wall Thickness (in.)

The pipe body Tensile Load (LT) is calculated by substituting the Specified Minimum Tensile Strength for the SMYS. Both are rounded to the nearest 10 lb. Internal Yield Pressure (Coiled Tubing) Internal Yield Pressure (Pr) is the internal pressure required to produce a stress on the ID of a tube with a minimum wall thickness equal to the specified minimum yield strength (SMYS). This calculation is based on the method detailed in API Bul. 5C3:

Pr = 2 x (SMYS) x tmin/D Where: SMYS = Specified Minimum Yield Strength D = Specified Outside Diameter (in.) tmin = Specified Minimum Wall Thickness (in.)

Hydrostatic Test Pressure (Coiled Tubing) The Hydrostatic Test Pressure (Pt) for coiled tubing is defined as the maximum internal fluid pressure recommended in testing the tube integrity, based on 80% of the internal yield pressure:

Pt = 0.8 x Pr Where: Pr = Internal Yield Pressure (psi).

Thus the hydrostatic test pressure is also based upon tmin. Except by special agreement, QT will not exceed an internal hydrostatic test pressure of 15,000 psi (103.4 MPa) Note on Duration of Hydrostatic Tests Unless otherwise agreed, Quality Tubing NOV will hydrotest each string to the pressure given for a minimum of 15 minutes. Longer periods and different pressures are mutually agreed during contract review.


www.nov.com

Collapse Pressure The collapse pressure (in the absence of axial stress) for as-manufactured coiled tubing is calculated using the appropriate formula from the API Bulletin on Formulas and Calculations for Casing, Tubing, Drill Pipe and Line Pipe Properties (API Bul. 5C3) for (a) Yield Strength collapse, (b) Plastic collapse, (c) Transition collapse and (d) Elastic collapse pressure. These values are then adjusted for the effect of ovality. In section 2 of the Technical Resource Manual download, collapse pressures for axial and torque loading, and for ovalled coiled tubing are also calculated. The results are extended to in-service coiled tubing. Values calculated from the formulas in API 5C3 are conservative for new tubing, since they represent a 95% confidence level that the material will collapse at a higher pressure. Torsional Yield Strength Torsional Yield Strength (Tf) is defined as the torque (in the absence of axial stress or pressure) that will stress the OD of the tube to the Specified Minimum Yield Strength (SMYS). Torsional Yield Strength is calculated from:

Tf = (SMYS) (D4 - d4) 105.86 x D Where: d = Calculated Inside diameter. Calculated values are rounded to the nearest 10 ft-lb.

Flow Area The flow area is calculated from

Flow Area = x (d/2)2 and given to 3 decimal places. d is the calculated inside diameter. This does not account for the possible presence of internal flash. Internal Capacity Internal capacity (Vi) in Gal/1000-ft. is the unit volume within the tube.

Vi = 40.8 x d2 External Displacement External Displacement (VD) in Gal/1000-ft. is defined as the volume of fluid that is displaced by the cross-sectional area of a tube body, in gallons per 1000 ft.

VD = 40.8 x D2

5 COILED TUBING, DRILL PIPE AND CASING STRETCH DATA When a pulling force is applied to oil well tubulars, they stretch by a predictable amount. In other words, tubulars are said to have elastic behavior when pulling forces acting on them are less than the materials yield strength. This behavior was discovered by Robert Hooke (1635-1702) who observed that the amount of distortion, or strain, was proportional to the stress or force applied, as long as the elastic limit (or more commonly, the yield strength) is not exceeded. The factors affecting the amount by which a tubular material will stretch are: (1) the length (in the direction of pull), (2) the amount of the pulling force or stress, (3) the cross-sectional area of the material, and (4) the materials elasticity constant (in engineering terms the Youngs Modulus or Modulus of Elasticity). General Stretch Formula

EALFS*

12**= Where: S = Stretch, inches F = Pull Force, pounds L = Length, feet E = Modulus of Elasticity, psi; for steel, E 30,000,000 psi A = Pipe metal wall cross-sectional area, in2.

Note: A common misconception is that the amount of stretch for an oil field tubular material is affected by the grade of steel (e.g., J-55, L-80, etc.). This is not true, because the modulus of elasticity remains the same. Higher grades of steel have greater yield strengths, and hence greater elastic limits. This means higher strength tubulars can be pulled to higher loads and therefore correspondingly stretch farther before reaching their elastic limits than the lower grades.

6 DETERMINATION OF THE FREE POINT The Free Point Constant makes it possible to determine very easily the length of pipe being stretched, commonly referred to as determining the free point in a string of stuck or anchored pipe, when the amount of pull force and amount of stretch is known. Refer to Free Point Constant from the table, Coiled Tubing Dimensions, Areas & Volumes - US Units, located in this document for the tubing involved, and use in the following formula:

FPCFLL *=

Where: L = *minimum length of free pipe, or length being stretched, feet. L = stretch, in. F = pull force, kips (1000 lb.) FPC = Free Point Constant (from par. 4 above).

NOTE: Because of friction forces, which cannot be determined readily, the actual length of free pipe may be longer than calculated. The formula necessarily assumes complete absence of friction. For example: Determine the minimum length of free pipe being stretched when a string of 1.50" OD x 0.095" wall coil tubing stretches 36 inches with an applied pull of 8,000 lb.

Procedure for Determining the Free Point for Stuck or Anchored Tubing There is a specific procedure for measuring the pull force and amount of stretch in the tubing for obtaining an accurate determination of the Free Point. The following procedure is used to ensure weight of any slack in the tubing is not added to the pulling force:

1. Either pick-up or snub the tubing so the injector load-indicator reads zero (the injector is neither pulling nor pushing the tubing through the striper).

2. Pick up the amount of the weight of the free tubing and there is no slack in

the string. Note: The weight of the free length of the string could be estimated. If the weight cannot be estimated, a good first assumption is half the weight of the total string length.

3. Mark the tubing (using marker pen or chalk) at the top of the preventer or other convenient non-moving reference point below the injector.

4. Pull on the tubing. Note: the combined pick-up load and pulling force

should not exceed the rated yield load for the tubing (refer to the Tubing Data table for the grade of tubing being used).

5. Mark the tubing at the top of the preventer or reference point again. The

distance between the first mark (made after the initial pick-up load) and the final pull is the D L used in the Free Point calculation.

6. Use the difference between the pick up load and the final load indicator

reading for the pulling force in the Free Point calculation.


www.nov.com

Calculating the Free Point Constant For any tubing size not included in the General Tubing Data Table, the Free Point Constant can be calculated as follows:

FPC = 2500 x Aw

For example: Determine the Free Point constant for 3.5" OD x 0.203" wall tubing: Determine the cross-sectional area of the tubing wall:

Aw = x (3.50 0.203) x 0.203 Aw = 2.1026 in2 FPC = 2500 x 2.1026 FPC = 5,257 ft.
