摘要： A wellbore fluid treatment may include a compound formed from reaction between cyclic anyhydride pendant groups on a polymer backbone with at least one amino acid, neutralized with a nitrogen containing compound. Methods may include injecting such a compound into a hydrogen production stream. Other methods may include reacting polybutadiene grafted maleic anhydride with at least one amino acid to produce an intermediate; and reacting the intermediate with an amide, amine, or imidazoline having at least a C4-C24 group to produce a compound.

摘要： A tool includes an internal assembly configured to be positioned at least partially within a body. The tool also includes a collet configured to be positioned at least partially within the body and axially-adjacent to the internal assembly. The collet includes a plurality of fingers that are circumferentially-offset from one another. At least one of the fingers includes a protrusion that extends adially-outward and is configured to be positioned at least partially within a recess formed in an inner surface of the body to secure the collet in place with respect to the body. The tool also includes a collet pin configured to be positioned at least partially within the body, axially-adjacent to the internal assembly, and at least partially within the collet. The collet pin is configured to contact the internal assembly to secure the internal assembly in place within the body.

摘要： A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
