Abstract: A modular reamer shoe for connection to an end of a tubular structure, such as a casing or liner, for deployment in a wellbore includes a body configured for connection to the tubular structure (casing or liner). The body includes a first section and an adjacent second section. The first section is connected to the second section such that torque can be transmitted between the first section and the second section. The first section defines a starter reamer defined by a plurality of first cutting elements and second cutting elements spaced from the first cutting elements. The reamer shoe has a plurality of actuatable blades disposed within the second area of the first section. The plurality of blades moves between extended positions and retracted positions. A nose is connected to the first section of the body. The second section is actuatable and can move in an axial direction so as to move the body, including the nose, in forward/rearward directions.

Abstract: A stage cementing differential valve tool includes a body extending from a first end to a second end. The body may include one or more ports that may be configured to circulate a cement slurry, an external sleeve may be slidably coupled to an outer surface to the body, and an internal sleeve assembly may be slidably coupled to an inner surface to the body. The external sleeve and the internal sleeve assembly may be configured to open and close the one or more ports. The stage cementing differential valve tool may also include a sealing element extending from the outer surface of the body that is configured to swell in a downhole fluid environment and a plug having shoulders with break-off points that is configured to actuate the internal sleeve assembly.

Abstract: A casing head support system (CHSS) for a casing head includes a casing head support unit (CHSU) having a tubular body with a support unit top end (SUTE) and a support unit bottom end (SUBE); a first conductor string extension joint coaxially fastened to the SUBE; and an internal load profile machined into an inner circumferential surface of the CHSU. The SUTE forms a coaxial connection with the casing head. The internal load profile supports a corresponding load shoulder on a conductor hanger. The CHSU contains a CHSU top preparation machined into the inner circumferential surface of the support unit. The CHSU top preparation is located at the SUTE. The CHSU top preparation mates with a corresponding casing head support unit running tool (CHRT) bottom preparation.
