Abstract: Job monitoring methods and apparatus for logging-while-drilling equipment are disclosed. A disclosed example method includes identifying a downhole scenario based on a property of an underground geological formation, selecting a first telemetry frame type based on the identified downhole scenario, conveying an identifier representative of the selected first telemetry frame type to a downhole fluid sampling tool, and receiving a first telemetry data frame from the downhole fluid sampling tool, the telemetry data frame containing fluid analysis parameters for a fluid, and being constructed in accordance with the selected first telemetry frame type.

Abstract: A method includes drawing formation fluid from a formation into a pressure test chamber of a downhole tool while the downhole tool is positioned at a location within a wellbore. The method also includes, while the downhole remains positioned at the location, measuring pressure of the formation fluid drawn into the pressure test chamber and operating a first pump to route additional formation fluid from the formation through the downhole tool and out into the wellbore. Still further, the method includes operating a second pump to expel the formation fluid from the pressure test chamber and to mix the formation fluid with the additional formation fluid such that the formation fluid expelled from the pressure test chamber is also routed through the downhole tool and out into the wellbore along with the additional formation fluid.

Abstract: A system can include edge devices that include communication circuitry; and one or more security components. A method can include receiving security codes from a plurality of edge devices without accessing the Internet: comparing the security codes without accessing the Internet; and, based at least in part on the comparing, connecting the plurality of edge devices for communication without accessing the Internet. A method can include executing a trained machine learning model on an edge device; and, based at least in part on the executing, detecting a change in state of the edge device.

Abstract: A method for routing a fluid within a flowline of a downhole tool is provided. In one embodiment, the method includes moving a piston within a chamber of a downhole tool to push a fluid out of the chamber and into a flowline. The method also includes using a pump in the downhole tool and in fluid communication with the flowline to route the fluid within the downhole tool via the flowline while moving the piston within the chamber. Additional systems, devices, and methods are also disclosed.
