Abstract: A wellbore assembly includes a pipe body and a chamber. The pipe body resides at a terranean surface of a wellbore and is fluidly coupled to a surface inlet of the wellbore. The chamber is coupled to the pipe body and has multiple slots each configured to house a wellbore component. Each slot revolves about a central axis of the chamber to align its respective wellbore component with a bore of the pipe body. The pipe body has a fluid inlet fluidly coupled to a pump that flows fluid to the pipe body. The fluid inlet is disposed upstream of the chamber. The pipe body directs the fluid from the fluid inlet to the inlet of the wellbore to push, from a first slot, a first wellbore component that is to be deployed downhole within the wellbore.

Abstract: Methods and systems for wellbore path planning are disclosed. The method includes defining total depth coordinates of a candidate wellbore path within a hydrocarbon reservoir, obtaining geoscience data for a subterranean region enclosing the hydrocarbon reservoir, and obtaining historical drilling data from an offset well in the subterranean region. The method further includes training a machine learning network to predict drilling hazard probabilities along the candidate wellbore path using the geoscience data and the historical drilling data. The method still further includes determining a first wellbore path to terminate at the total depth coordinates using the candidate wellbore path and the trained machine learning network.

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.
