A threaded oilfield tubular connectionincludes a pin memberhaving a first external tapered threadand a second external tapered thread. A box member includes a first internal tapered threadand a second internal tapered thread. Helical torque shouldersare provided on the pin member and the box member, and an axially spaced between the respective first and second threads. The helix of each torque shoulder includes a plurality of revolutions with compression flanks on both the pin member and the box member.

Oilfield tubular connection with increased compression capacity

A thread form having improved strength and fatigue resistance. The root of the thread may be cut on multiple cutting radii having displaced centers. At least two of the root surfaces formed by cutting radii may have lengths that are greater than the root truncation. The threads may be used in a double start configuration to increase the connection strength and reduce makeup and breakout rotations.

Fast make-up fatigue resistant rotary shouldered connection

A thread form having improved strength and fatigue resistance. The root of the thread is cut on multiple cutting radii having displaced centers. At least two of the root surfaces are formed by cutting radii having lengths that are greater than the root truncation. The threads are used in a double start configuration to increase the connection strength and reduce makeup and breakout rotations.

The present invention includes a downhole component adapted for transmitting downhole data. The downhole component includes a threaded end on a downhole component. The threaded end furthermore includes an interior region, and exterior region, and a mating surface wherein a cavity is formed. A data transmission element is disposed in the cavity and displaces a volume of the cavity. At least one passageway is formed in the threaded region between interior and exterior regions. The passageway is in fluid communication with both the interior and exterior regions and thereby relieves pressure build up of thread lubricant upon tool joint make up.
