32 results about "Shale shakers" patented technology

Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling. They are the first phase of a solids control system on a drilling rig, and are used to remove large solids (cuttings) from the drilling fluid ("mud").

Bypass diverter box for drilling mud separation unit

A bypass diverter box disposed upstream from conventional solids control equipment of a mud system of a drilling rig contains a drilling mud separation unit having a continuous-loop scalper screen that is driven in a continuous loop to separate, convey and discharge large amounts of gumbo, heavy clays and drill solids at the end of the separation unit. The flow divider box is a box-like housing with a verter plate, upper and lower baffle plates and a grate that allows drilling fluid or drilling mud to be selectively directed to the mud separation unit to be separated prior to passing to the conventional downstream solids control equipment or allows the fluid to bypass the separation unit and flow directly to the conventional solids control equipment. The bypass diverter box baffle plates, diverter plate and grate, and selective utilization of the mud separation unit removes large amounts of gumbo, heavy clays and drill solids from the drilling mud and allows high flow rates to be easily processed by shale shakers and other conventional downstream solids control equipment of the mud system and compliments the drilling operations with respect to changes in the lithology, geological formations, or loss of returns in relation to the gallons pumped or folume of drilling fluid or drilling mud entering the bypass diverter box.

Weir box for drilling mud separation unit

A weir box disposed upstream from conventional solids control equipment of a mud system of a drilling rig contains a drilling mud separation unit having a continuous-loop scalper screen that is driven in a continuous loop to separate, convey and discharge large amounts of gumbo, heavy clays and drill solids at the end of the separation unit. The flow divider box is a box-like housing with a diverter plate, weir baffle plates and a sliding gate that allows drilling fluid or drilling mud to be selectively directed to the mud separation unit to be separated prior to passing to the conventional downstream solids control equipment or allows the fluid to bypass the separation unit and flow directly to the conventional solids control equipment. The sliding gate is adjustable to selectively control or meter the flow rate and to create a hydrostatic head upstream from the conventional solids control equipment. The weir box baffle plates, sliding gate, and selective utilization of the mud separation unit allows the operator to produce an increased hydrostatic head, which enables high flow rates to be easily processed by shale shakers and other conventional downstream solids control equipment of the mud system and to compliment the drilling operation with respect to changes in the lithology, geological formations, or loss of returns in relation to the gallons pumped or volume of drilling fluid or drilling mud entering the weir box.

System and method for separating, monitoring and sampling coiled tubing flow back returns

InactiveUS20080236822A1Quickly and safely identifyMinimize hazardDrilling rodsFluid removalShale shakersCoiled tubing
The invention relates to a system and method for separating, and safely monitoring and sampling flow back fluid returns from coiled tubing operations in oil and natural gas wells. The system comprises a flow back tank; one or more gas diffusers; one or more shale shakers; and a chute, which diverts flow from the gas diffusers to a sampling site positioned near the perimeter of the flow back tank. The system also has a volume level indicator on or near the perimeter of the flow back tank. The method comprises piping fluid returns from a wellbore, separating the trapped gases from the fluid returns, directing the degassed fluids to a shale shaker to separate the solids and directing the separated solids and liquids into separate tanks for analysis and reconditioning, if necessary. Cleaned liquids may be recirculated back to the wellbore.

Separation of evolved gases from drilling fluids in a drilling operation

InactiveUS20050269137A1Minimizes drilling interruptionAvoid evolutionDrilling rodsConstructionsDegasserShale shakers
A fluid handling system for drilling cuttings utilizes a constant and gravity managed liquid level between a substantially atmospheric separator and a shale shaker to maximize fluid residence time within the separator and ensure substantially all of the gas entrained in the cuttings is evolved and passed to a flare thus preventing evolution of the gas at the shale shaker. Solids from the separator are combined with liquid recirculation from and returning to the shale shaker. Optionally, a vacuum degasser is positioned between the separator and the shale shaker and separated gases are passed from the degasser to the flare. This method and system is particularly applicable to balanced, underbalanced and air drilling operations where the flow of gas is intermittent and unpredictable.
