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: Tools and methods are used to determine the oil, water, and solids volume fractions in a drilling fluid at the rig site. The volume fractions can be determined in-line with returned drilling fluid by using an NMR magnet and a flow line or sample chamber that receives a fluid sample and loads it into the NMR magnet. Using an RF probe, spectrometer, and computing device, data processing and interpretation of NMR data from the spectrometer is performed, while also raising a flag when iron contamination exceeds a predefined threshold.

Abstract: A drilling fluid management system may receive a measurement of measured drilling fluid properties for a drilling fluid. A drilling fluid management system may compare the measurement of the measured drilling fluid properties to setpoint drilling fluid properties to generate a difference between the measurement and the setpoint drilling fluid properties. A drilling fluid management system may, based at least in part on the difference between the measurement and the setpoint drilling fluid properties, prep are a recommendation to return the drilling fluid to the setpoint drilling fluid properties.
