Abstract: A method for determining a screen break may include obtaining a fluid stream after a screening system in a drilling process; placing the fluid stream into a screen break detector; obtaining a pressure within a well of the screen break detector when the screening system is in a first state; obtaining a pressure within the well of the screen break detector when the screening system is in a second state; determining a differential pressure within the well of the screen break detector obtained when the screening system is in the second state compared to the pressure when the screen break is in the first state; and transmitting a notification to an operator when the pressure within the screen break detector obtained when the screening system is in the second state is greater than the pressure within the screen break detector when the screening system is in the first state.

Abstract: A device for aging a drilling fluid includes a housing. The device also includes a lower cap that is configured to be coupled to or integral with a lower end of the housing. The device also includes an upper cap that is configured to be coupled to an upper end of the housing. The upper cap has an upper cap hole formed therethrough. The device also includes a piston that is configured to be positioned within the housing and between the lower and upper caps. The piston is configured to move axially within the housing in response to a pressure differential across the piston. The piston has a first piston hole formed therethrough.

Abstract: A method for evaluating drilling fluid includes making an NMR measurement of a sample of the drilling fluid and inverting the measurements to compute a corresponding T1T2 plot. The T1T2 plot is in turn evaluated to characterize the drilling fluid. In one embodiment, a stability index of the fluid may be computed from multiple NMR measurements made while aging the sample.

Abstract: Back pressure control devices used to control fluid pressure in a wellbore require various utilities for operation, such as an air supply. Apparatus disclosed herein provide for the continued operation of one or more back pressure control devices when supply of utilities for operation of the back pressure control devices are intentionally or unintentionally interrupted.

Abstract: A method of reducing fluid loss includes pumping a wellbore fluid including resin coated solid particulate into a wellbore having fractures therein, the resin coated solid particulate forming a substantially impermeable plug in the fractures. A method of drilling a wellbore includes drilling a wellbore through a formation using a first wellbore fluid; and upon experiencing a fluid loss event to the formation, pumping a second wellbore fluid including resin coated solid particulates into the wellbore.

Abstract: Wellbore fluids may contain alkyl amine and cyclic organic acid complexes capable of controlling hydration in swellable formations such as shale- and clay-containing formations. Further, methods of drilling may utilize wellbore fluids containing a base fluid and a complex of alkyl amine and a cyclic organic acid.

Abstract: An apparatus includes a materials separator that includes a continuous filter belt disposed around a plurality of rollers. The apparatus also includes a pressure differential system operatively coupled to the separator and configured to adjust a pressure differential across the continuous filter belt. A vacuum is applied to the continuous filter belt and a fluid portion of the slurry on the continuous filter belt is drawn through the continuous filter belt. An apparatus includes a materials separator having a first deck with a first continuous filter belt and a second deck with a second continuous filter belt.

Abstract: This disclosure is drawn systems, devices, apparatus, and/or methods related to the separation of a mixture of solids according to size and the separation of solids from liquid. Specifically, this disclosure is drawn to an adjustable weight set for use on vibratory separators. In some examples, the adjustable weight set may include a base plate rotatable about an axis and extending radially outward from the axis; a plurality of slots extending through the base plate and being disposed between a radially outward periphery of the base plate and the axis; a plurality of weights coupled to each other about the base plate; and a weight locking tab that partially surrounds the base plate that may include one or more hooks extending through a portion of a slot.
