The PTech+ connection provides increased torque while still maintaining a streamline geometric design. Torque capacity averages 65% †80% greater than API connections of the same OD and ID dimensions and 10% †30% greater than most proprietary high torque connections of the same OD and ID dimensions.
The combination of a slow taper and large radius thread root allows each PTech+ connection to have smaller OD’s and larger ID’s and still maintain a balanced connection. The large single root radius considerably reduces peak stresses in the connection and reduces the connections stiffness.
Comprehensive testing includes: FEA, Torsion to Failure, Repetitive Makeâ€Up and Breakâ€Out, and Comparative Fatigue.
â— A 3D Method was used to evaluate an overall connection peak stress and SCF (Stress Concentration Factor). The PTECH+ Design Models were numerically analyzed using ANSYS® X64ed. V12.1 to show the stress in the connection at both minimum and maximum internal gap tolerances due to makeâ€up torque.
â— 100 Make and Breaks were accomplished without galling on either the pin or box connection.
The PTech+ Connection provides turns to makeâ€up similar to API… and fewer turns to makeâ€up than certain other proprietary connections.
◠PTech39+ Connection †7.5 Turns
NC40 Connection †6.5 Turns
◠PTech55+ Connection †8.8 Turns
◠PTech59+ Connection †9.3 Turns
5â€1/2 FH Connection †9.8 Turns
◠PTech68+ Connection †8.4 Turns
6â€5/8 FH Connection †9.8 Turns
Results of extensive field use demonstrate the costâ€saving opportunity with the PTech+
connection. Cost of ownership and repair is less than other high torque products in the marketplace.
â— A string was used for 18 months to drill 16 wells (average 21,105 feet per well) in the North Dakota Bakken, before some of the string began to require replacement.
â— DSâ€1 Service Category 5 inspection frequency was every 4th well drilled.
