Abstract: A pipe coupling device includes a body configured to connect a first pipe segment to a second pipe segment, a sealing device carried by the body, and an activation unit. The sealing device includes a circumferential element including a first material and a peripheral element connected to an edge of the circumferential element and including a second material that is different from the first material. The activation unit is configured to adjust the sealing device to an activated state in which the sealing device extends radially from the body to form at least a portion of a seal with a pipe that surrounds the body, such that the seal fluidically isolates a first annular region between the first pipe segment and the pipe along a first side of the seal from a second annular region between the second pipe segment and the pipe along a second side of the seal.

Abstract: A system and a method for reducing annular pressure with a casing annulus pressure release system are described. The casing annulus pressure release system includes a controller, multiple sensors, and a pressure release sub-system disposed a wellbore annulus. The sensors sense wellbore conditions in the annular space and transmit signals representing the sensed wellbore conditions to the controller. The pressure release subsystem releases pressure in the annular space into the wellbore in response to a signal from the controller.

Abstract: A smart system for circulating LCM can implement a method. While a wellbore is being drilled in a geologic formation, drilling parameters identifying wellbore drilling conditions of a wellbore drilling system drilling the wellbore are received. The wellbore drilling system flows a wellbore drilling fluid including particulates of different size distributions. The particulates operate as LCM to reduce loss of the wellbore drilling fluid in the geologic formation. Size distributions of the particulates in the wellbore drilling fluid flowing through multiple different wellbore fluid flow pathways of the wellbore drilling system are received. The size distributions represent a concentration of the particulates in the wellbore drilling fluid. A release of certain particulates into the wellbore drilling fluid is controlled based, in part, on the received drilling parameters and the received size distributions of the particulates.

Abstract: An unbalanced sub-assembly includes a turbine and a shaft coupled to the turbine at a first end of the shaft. The unbalanced sub-assembly is capable of rotating and imparting a vibration to the casing in response to a fluid being passed through the casing. A rupture disc is positioned on one end of the unbalanced sub assembly. The rupture disc is configured to rupture above a specified differential pressure threshold caused by fluid flowing through the vibration assembly. The rupture disc is capable of allowing the fluid to bypass the unbalanced sub assembly when the rupture disc is in a ruptured state. The rupture disc directs fluid through the unbalanced sub assembly when the rupture disc is in an un-ruptured state.
