摘要： A well drilling tool has a tubular member connected into a casing string that serves as a drill string. A load shoulder is located within the bore of the tubular member. The load shoulder has a torque transferring portion that extends from a lower terminus to an upper terminus. The load shoulder has an axial force transferring portion that faces upward. A bottom hole assembly is lowered through the casing string and lands on the load shoulder. The bottom hole assembly has a mating profile to the load shoulder so that it will be supported by the load shoulder and will receive torque transferred from the load shoulder.

摘要： A cement float collar can be positioned downhole and used in a wellbore completion operation after drilling a wellbore with casing. The cement float collar is made for pumping downhole and into engagement with a groove formed in the casing, called the profile nipple. As such, no restriction is needed in the casing for accepting or latching the float collar and the portion of casing including the groove can be installed at the start of the drilling operation. In addition, the profile nipple can be used to engage other drilling tools and, therefore, can already be in placed when the final well depth (TD) is reached.

摘要： A method for securing a wellbore string device to a wellbore liner tubular employs a swelling elastomer to frictionally grip a gap between the wellbore string device and the liner tubular. The swelling elastomer is positioned between the wellbore string device and the wellbore liner tubular, then activated to cause it to swell to engage the wellbore string device with the wellbore liner tubular. The wellbore string device may be a centralizer, a wear band or a torque ring.

摘要： A cement float collar is disclosed that can be positioned downhole and used in a wellbore completion operation after drilling a well-bore with casing. A wellbore drilling and completion method is also disclosed. The cement float collar is made for pumping downhole and into engagement with a groove formed in the casing, called the profile nipple. As such, no restriction is needed in the casing for accepting or latching the float collar and the portion of casing including the groove can be installed at the start of the drilling operation. In addition, the profile nipple can be used to engage other drilling tools and, therefore, can already be in place when the final well depth (TD) is reached.

摘要： Centralizer includes a body formed of a first material and an outer shell formed of a second material. The outer shell is installed to resist destructive damage and longitudinal creep of the portion formed of the first material. The outer shell covers the entire exterior surface of the body, including ribs that protrude from the exterior surface. The outer shell material is more durable than the material of the body. The outer shell material may be steel and the body material may be a polymer. The ribs and exterior surface of the body bond to the outer shell. The centralizers fit on well pipes to centralize them within boreholes.
