A system includes a fluid conduit, a fluid chamber in communication with the fluid conduit, a rheology sensor in communication with the fluid chamber, and an electric temperature controller in communication with the fluid chamber. The fluid chamber is cooled in response to a first control signal from the electric temperature controller.

Automated analysis of drilling fluid

A system includes a fluid conduit, a fluid chamber in communication with the fluid conduit, a rheology sensor in communication with the fluid chamber, and an electric temperature controller in communication with the fluid chamber. The fluid chamber is cooled or heated in response to a first control signal from the electric temperature controller.

An apparatus may include a centrifuge bowl rotatable about its longitudinal axis, a discharge unit positioned to receive discharge fluid from the centrifuge bowl, a diverter fluid circuit in communication with the discharge unit, a measurement region of the diverter fluid circuit with a narrower diameter than a cross section of the discharge unit, and the diverter fluid circuit oriented to direct a portion of the discharge fluid from the discharge unit to the measurement region.

Centrifuge system with a measurement region of a diverter fluid circuit

A bob for a viscometer in a portable rheology unit is provided. The bob may include a bob portion having a cylindrical portion and a first end portion, the cylindrical portion defining a first end of the bob. The bob may also include a plastic portion interfacing with an interior surface of the first end portion, wherein the plastic portion includes a conical area extending from a conical area first end to a conical area second end, and the conical second end is connected to an interior surface of the cylindrical portion. The bob may also include a sleeve portion connected to the plastic portion and a bob second end portion connected to the sleeve portion.

Bob and shaft designs for portable rheometry units

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.

Digital retort measurement systems and methods

A system having a screen having an upper side and a lower side for separating drill cuttings and drilling fluid within a vibratory separator; a tray positioned below the screen for receiving the drilling fluid from the screen; a pressure differential generator coupled to the tray, the pressure differential generator configured to create a pressure differential between the upper side and the lower side through the screen to enhance the flow of drilling fluid through the screen; and a hose assembly coupling the pressure differential generator to a coupler, an inlet of the coupler being arranged perpendicularly between a first outlet coupled to a mist eliminator and a second outlet coupled to a tank.

Apparatus, system and method for separating components of a slurry

This disclosure is generally drawn to systems, devices, apparatuses, and/or methods, related to monitoring a shaker used for separating solids from fluid. 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.

Shaker imaging and analysis

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.

Apparatus, system and method for flowing a fluid through a trough

An apparatus includes a vibratory separator with a top deck, a middle deck, and a bottom deck, and a collection trough coupled to at least one of the top deck, the middle deck, and the bottom deck. The collection trough includes a collection container having an inlet configured to receive a material retained on the at least one of the top deck, the middle deck, and the bottom deck, and a sloped surface configured to guide the material from the inlet to an outlet of the collection container, and a pressure differential generator disposed proximate the outlet of the collection container.

Recovery hopper trough for vibratory separator and method

An apparatus including a screen capable of separating solids from a liquid-solid mixture and a first probe disposed beneath the screen. The first probe is provided to determine a position of a beach between the liquid-solid mixture and separated solids. The apparatus may measure a property of a local volume of a probe disposed beneath a first separator deck. The probe may then send a first signal to database. Based on the signal a location of a beach may be determined.
