Abstract: An integrated casing joint, casing assembly, and method is disclosed. The integrated casing includes a tubular portion and a pair of tubular joint ends. The pair of tubular joint ends are positionable at opposite ends of the tubular portion. At least one of the pair of tubular joint ends includes an upset end integrally formed with the tubular portion. The upset end has equivalent mechanical strength with the tubular portion, and is matably connectable to one of the pair of tubular joint ends of an adjacent casing joint to define an integrated casing connection therebetween whereby casing performance is optimized.

Abstract: The current invention provides a drill pipe of standard weight with an integral wear pad. The drill pipe with integral wear pad provides increased durability while retaining the strength, flexibility, lightweight, and other performance characteristics of standard weight drill pipe. The current invention also provides methods for making a standard weight drill pipe with integral wear pad.

Abstract: A heavy weight drill pipe member is disclosed for use in drilling high angle and horizontal well bores in a corrosive environment. The heavy weight drill pipe member consists of a tubular member with a longitudinal bore therethrough, and includes connectors or tool joints attached at each distal end for connecting additional heavy weight drill pipe members. The tubular member and tool joints are preheated, water quenched and tempered to obtain a unique combination of hardness, a yield strength and impact strength for improved resistance to stress corrosion cracking and hydrogen embrittlement in a hydrogen sulfide environment. The tubular member includes a plurality of wear pads or protectors equidistantly spaced along the longitudinal axis of the tubular member to reduce bending stress in the pipe by limiting the degree of bend when the pipe is placed in compression in a high angle well bore.
