摘要： Systems and methods for managing equipment in a workspace such as an oil rig are disclosed. Objects are given zones which are physically larger than the objects. A monitoring system is capable of monitoring the objects and the zones for each object. When zones intersect, a collision is possible and the monitoring system can take action to prevent the collision or mitigate damage in the case of a collision. Further, systems and methods for ensuring the moving components are handed-off properly from one support to another are disclosed.

摘要： A plug assembly includes an expandable assembly and a locking ring. The expandable assembly is adapted to be deformed radially over the locking ring. The plug assembly is used with an untethered object, which is adapted to contact an inside surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause further radial deformation of the expandable assembly, and penetration of an internal surface of the tubing string at least at one point with a gripping portion of the expandable assembly.

摘要： New apparatus and methods are provided for positioning and attaching centralizers to the inside sidewalls of a wellbore. One or more centralizers are maintained in the interior of a pipe that is transported downhole into a well for deployment. Preferrably, the pipe is also the wellbore 's casing and the centralizers are deposited in a top-down manner as the casing travels downhole. The centralizers of the present invention are constructed to have an at least partially circular structure with a central hole. The preferred centralizer has an expanding circular structure wherein the diameter of the centralizer is substantially uniform so as to form an annular construction. Once deployed, the annular centralizer expands to engage the wellbore sidewall with the central hole expanded for passage of the well casing.

摘要： A constant force device has at least a first non-constant axial force driving the first set of arms and a second non-constant axial force driving the second set of arms, where the two sets of arms are offset from one another by 900. Each of the non-constant axial forces is converted to a radially extending force by the interaction of a force guide and actuator. The force guide is attached to the inner mandrel of the constant force device and is shaped to produce an essentially constant radially extending force through the entire range of motion of the arms. Typically each arm of the pair of arms has a pivoting arm and a telescoping arm where the joint between the pivoting arm and telescoping arm has one or more wheels to reduce friction as the constant force device moves through the tubular.
