drilling with said tubular casing string while the wear resistant connections shown in fig2 and 3 are useful for applications where the bend angle u03b1 is allowed to vary randomly in accordance with typical industry practice for manufacture and assembly of threaded and coupled casing connections in certain applications it is desirable to control the magnitude of said lateral reaction force in at least one interval of an assembled casing string which lateral reaction force is dependent on several design variables including casing flexural stiffness spacing between contacting bent connections axial load relative radial orientation of connection bends and radial interference of local bent section as controlled by the magnitude of the connection bend angle u03b1 to control of lateral load arising in an interval of a casing string it is useful to control the bend angle geometry and spacing along that string interval this can be done by surveying couplings and casing joints to determine the bend angle magnitude at a connection of selected ones of the couplings and casing joints and selecting the couplings and casing joints to be used in the string interval referring now to fig5 in an alternate embodiment of the present invention a bent wear resistant connection 101 largely as shown in fig2 is provided but where the center axis 6 x of the mill end box 6 and the center axis 8 x of the field end box 8 are offset out of alignment to form a bent coupling 103 having an angle u03b2 between axes 6 x and 8 x a wear pad 113 is positioned on the outer surface of.
