Abstract: A worksite safety tracking system includes at least one network comprising a plurality of communicatively coupled electronic devices and at least one mobile tracking device communicatively coupled to the network. Alerts are generated by the network based on locations of the tracking device within the worksite.

Abstract: An example system for conditioning drilling fluid includes a tank to hold drilling fluid and outlet conduits located at least partly within the tank. The outlet conduits have a tree structure that includes a trunk and branches. Each of the branches has one or more nozzles for outputting drilling fluid within the tank. The system also includes one or more inlet conduits for receiving drilling fluid from the tank and one or more pumps that are controllable to suction the drilling fluid from the tank through the one or more inlet conduits and to force the drilling fluid into the tank through the outlet conduits.

Abstract: A machine-learning ecosystem includes a correlation module for building at least one prediction model based on at least one data input including at least one input parameter and at least one output parameter, the prediction model relating the output parameter to the input parameter. The correlation module performs at least one threshold check on the prediction model to assess the robustness of the prediction model. The ecosystem further includes a decision module communicatively coupled to the correlation module and receiving the prediction model from the correlation module. Based on a verification check at the decision module, a confirmation, a deferral, or a rejection of the prediction model is sent from the decision module to the correlation module.

Abstract: Logging electronics are housed within a tool housing. A first coolant reservoir is housed within the tool housing. A second coolant reservoir is housed within the tool housing. A tubing length defines a coolant passage. The tubing length fluidically connects the first coolant reservoir to the second coolant reservoir. A portion of the tubing length is adjacent to the logging electronics. A flow regulator is within the coolant passage. The flow regulator regulates a coolant flow between the first coolant reservoir and the second coolant reservoir.

Abstract: An example system for isolating cement slurry from drilling fluids includes a tool configured for installation on a landing collar of a casing. The tool includes a base that conforms to an inner circumference of the casing and a tube that extends uphole from the base. The tube has a first borehole that extends downhole through the base. The tube is perforated to allow cement slurry to pass from the casing into the first borehole. A cementing plug is configured to seal to the casing uphole of the base. The cementing plug includes a second borehole to receive the tube. The cementing plug includes a covering that extends across at least part of the borehole and that is configured to break in response to contact with the tube.

Abstract: An example wellbore cementing system includes a casing to line at least part of a wellbore, and a pipe to introduce cement slurry containing capsules into the wellbore. The capsules include an accelerator. The accelerator reacts with the cement slurry to affect a thickening time of the cement slurry. The example system also includes a substructure having shearing pins. The substructure is arranged to receive the cement slurry from the pipe. The substructure is configured rotate to break at least some of the capsules in the cement slurry.
