Note: These are OEM values that may vary with actual values due to mill tolerances, IPC tolerances, OEM rounding, and other factors. Pipe is purchased at a guaranteed 95% RBW. IPC is applied to a nominal thickness of 0.009''. Pipe will have an ID of 4.72'', which is smaller than pipe purchased at 87.5%.

Standard vs. Extended MUT for Delta™

Delta™ is the fourth generation of double shoulder connection developed by Grant Prideco™. As

part of the connection development cycle, customer feedback regarding past connections as well

as lessons learned were incorporated. There was a concerted effort to create a product that

meets customer demands for performance while being easier to operate, and providing a

reduced total cost of ownership. Grant Prideco recognizes there are limits to rig capabilities and

any new product offering must be usable without substantial investment while having the ability

to support the needs of future wells.

Delta has been designed with a standard maximum recommended make up torque (MUT) which

is provided as a part of our documentation when ordering. The standard maximum MUT is at or

slightly above those seen on most XT™ connections with the same OD and ID. This provides

existing rigs the ability to transition from one connection to the other without making a

substantial investment. Grant Prideco does recognize however that wells of the future, and even

some existing challenging wells now, do require a maximum MUT above those seen with XT

today. As such Delta, by default when purchased, can utilize an extended MUT to further increase

the product torque output but makeup to this level is not required by default.

An example is shown below for reference:

For Delta™ 544 6.625 x 4.0 (130,000 psi tool joints)

Standard Maximum MUT: 50,300 ft-lbs with 1.0 friction factor

Extended Maximum MUT: 58,700 ft-lbs with 1.0 friction factor

Both the standard and extended MUT values can be adjusted as well. Please note the maximum

friction factor allowed is 1.15 which yields the below results:

Standard Maximum MUT: 57,800 ft-lbs with 1.15 friction factor

Page 2 of 2 ©2017 NOV | Proprietary and confidential PR-43.0-2017Jan26-EXT

Extended Maximum MUT: 67,500 ft-lbs with 1.15 friction factor

This option of a standard and extended MUT provides users confidence to purchase a product

which will support them now and in the future. Please contact Grant Prideco for more details

regarding the performance of the Delta series of connection and what it can provide.
