A method, apparatus and system for locating external apparatus mounted to a tubular in a wellbore. The identification of apparatus, such as cable clamps, enables other tools in the string to operate more precisely. A computer model is used to locate the apparatus from acoustic images, which images are acquired using a downhole device having an acoustic sensor or acoustic array. The model may be a classifier, which may be machine trained to classify whether an apparatus is present, its location and its orientation. Automating this locating enables very long wellbores to be processed quickly.

The method of providing a clamping connection comprising providing one or more clamping hubs, providing two or more clamping segments to engage the clamping hubs, constraining the clamping segments to move approximately radially with respect to the clamp hubs, providing a tension band around the clamping segments which slides circumferentially relative to the clamping segments, and adjusting the ratio of the contact area of the tension band to the clamping hubs and the area of the clamping hubs to compensate for the difference in loading on the clamping hub due to sliding friction between the tension band and the clamping hubs.

A casing rotation system permits rotation of a casing string through a telescoping ring that selectively engages a casing hanger. When the telescoping ring is in a first axial position, it engages the casing hanger such that rotational force is transmitted from a running tool to the casing string. When the telescoping ring moves to a second axial position, it disengages the casing hanger such that rotational force is no longer transmitted to the casing string. The casing rotation system may include an inward-biased locking ring disposed about the casing hanger and optionally a bearing surface that reduces friction on the hangar.

A method of monitoring a condition of a connection between two bodies which are connected using a connector. The connector has a sensor assembly which provides an output representing a degree of movement of one or both of the two bodies. The method includes installing the connector and the two bodies in a use position in which the connector joins the two bodies, and using the output from the sensor assembly and a numerical model to determine a force on one or both of the two bodies or of the condition of the connector. The numerical model is a record of test forces applied to a test element secured to the connector or of a test connector having a same configuration as the connector and a corresponding output from the sensor assembly of the connector or of the test connector during and/or after the application of each test force.

A system includes a quick access casing coupling, a drill string, a whipstock, a lateral entry locator, a logging tool, and a drill bit. The quick access casing coupling has an inner profile and is installed on a tubular body. The whipstock has a whip face and is removably connected to the drill string. The lateral entry locator is connected to the whipstock and includes an outer surface designed to engage with the inner profile of the quick access casing coupling. Engagement of the outer surface and the inner profile orients the whip face towards a planned location of a lateral. The drill bit is connected to the drill string and is configured to kick off from the whip face into a portion of the circumferential wall adjacent to the planned location to drill the lateral.

Present embodiments relate to a riser bolt torque device that is configured to couple a first riser joint to a second riser joint to form a riser of a subsea drilling system. The riser bolt torque device includes a first arm and a second arm, multiple torque tools supported on the first arm and the second arm, and one or more actuators configured to drive the first arm and the second arm to pivot relative to one another from an open configuration to a closed configuration to enable alignment between the multiple torque tools and a flange of the first riser joint.

A unitized wellhead assembly includes a lower wellhead housing and an upper wellhead housing interconnected by internal and external threads and pressure sealed via a housing seal that creates a unitized body. The unitized wellhead assembly accepts casing and tubing hanger assemblies containing a plurality of individual retainer segments that engage mating grooves in the unitized body and also retains the casing and tubing hangers in place while containing the wellbore pressure. By eliminating the porting for external actuation devices that pass through the wall section of a wellhead housing, the potential for accidental release of wellbore gasses or fluids to the atmosphere and creation of a potentially hazardous or deadly situation is eliminated. Additionally, the configuration of the segmented retainers reduces high stresses when the retainers are forced outward and eliminates the potential to yield a retainer ring beyond the point of being able to return to its original shape.
