摘要： A method for logging in a well is disclosed. The method includes securing a passive logging while levitating (PLWL) assembly to a bottomhole assembly (BHA) to form a logging assembly and running the logging assembly into a wellbore of the well. The method further includes detecting a deviation in the wellbore, detecting a fluid flow direction around the logging assembly in the wellbore, activating the PLWL assembly based, at least in part, on the deviation in the wellbore and the fluid flow direction, and levitating the logging assembly in a center of the wellbore. The method also includes determining whether the logging assembly has reached a target depth and performing logging in the well while the logging assembly is levitating in the center of the wellbore.

摘要： A device for hydraulically operating a drive wheel of a wellbore tractor has, in certain embodiments, at least one cam and a rotatable assembly arranged to be rotatable with respect to the cam about an axis of rotation. The rotatable assembly has at least one piston. The device also has a chamber and at least one supply port for supplying hydraulic fluid from the chamber to the piston for energizing the piston, the supply port being arranged to be moved between first and second positions relative to the cam. In the first position, the piston can connect to the supply port and be energized to impart force against the cam for producing forward rotation of the assembly. In the second position, the piston can connect to the supply port and be energized to impart force against the cam for producing reverse rotation of the assembly. Related distributor assembly, wellbore tractor, and method are also described.

摘要： A modular mobility platform has extendable and retractable tractor treads for engaging the walls of a downhole environment. The extendable and retractable tractor treads allow the platform to successfully navigate longitudinally through the downhole environment. The platform is composed of a plurality of different modules removably interconnected together longitudinally. Each module has at least one specific function, such as sensing, navigation, mobility, control, communication, power, or a combination thereof. The platform has longitudinally-directed detectors for detecting the forward or reverse direction through which the platform is to travel. A system and method use the modular mobility platform.
