Technical Bulletin – Thread Compound Friction Factors

A thread compound traditionally has two primary functions when applied to a rotary shouldered connection (RSC) in a drill
string. The first role is the prevention of metal to metal damage (ie. anti-galling) of thread flanks and seal surfaces from the
extremely high local contact stresses in the RSC. The second role is to function as lubrication during spinup and makeup of
the RSC, reducing friction and thereby ensuring that makeup torque properly loads the seal faces and thread flanks of the
connection.

This bulletin seeks to define and educate operators on thread compound friction factors and their usage.
