Title: METHOD AND APPARATUS FOR CONNECTING WELL EQUIPMENT
Abstract:
A wellbore equipment assembly and components for a wellbore equipment assembly are disclosed along with a method of connecting wellbore string components. In some embodiments, the assembly includes a first component and a second component with an end portion received in an end of the first component defining a connection or a joint. The first and second components include corresponding threads that together define a threaded region of the joint or connection. The first and second components also include corresponding interface surfaces that together define an interface region of the joint or connection that is spaced apart from the threaded region. The interface surfaces are sized such that the interface surface of the second component is urged into frictional engagement with the interface surface of the first component to bear at least part of a torque applied to the assembly.
