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.

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.

Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to capturing infrared images of a shaker or components thereof (e.g., shaker baskets, decks, screens) and performing actions on the shaker, its components, and/or the its operation based at least in part on the captured infrared images.

Abstract: A method, apparatus and system for flowing a fluid from an inlet flush nozzle onto tiered plates in a trough is provided. Material may fall from a deck in a vibratory separator, such as a shale shaker, into the trough, which is attached to the separator. The trough has a main inlet and the inlet flush nozzle that opens to tiered plates. An external pipe may feed the fluid into the main inlet and the inlet flush nozzle to lubricate the tiered plates in the trough. Material falling from the vibratory separator may float on the fluid to flow toward an outlet of the trough. A single plate with perforations may be used instead of the tiered plates to permit the fluid to penetrate the perforations to suspend the material, allowing the material to flow across the single plate to an outlet.

Abstract: A protection circuit for an integrated circuit product die or die-let (die-let) is responsive to whether the die-let has undergone a dicing operation or not. A test circuit on the die-let's semiconductor wafer can test and/or configure the die-let. After the dicing operation, the protection circuit generates a signal to isolate the cut input lines from the test circuit to prevent any interference with the normal operation of the integrated circuit product die-let.
