Abstract: Methods, systems, devices, and products for evaluating a downhole fluid in a borehole intersecting an earth formation. Methods include using ultrasonic irradiation to produce sonoluminescence from cavitation in a volume of the fluid; obtaining spectral information from measurement of the sonoluminescence with a light-responsive device; and estimating a parameter of interest of the fluid from the spectral information. The parameter may be a composition of the fluid or concentration of: i) at least one chemical element in the volume; i) at least one molecular element in the volume. Methods include deconvolving a response spectrum by using one or more separately determined standard spectra, or estimating the parameter of interest using spectral lines represented by the spectral information.

Abstract: A method for making a beaded matrix includes positioning two or more beads near one another. Accelerating the two or more beads toward one another; and impacting the two or more beads with one another so that electrons are shared between molecules thereby fusing the two or more beads together.

Abstract: An assembly for use to cement an uncased wellbore and create a sidetrack of a wellbore with a single trip into the wellbore. The assembly includes a mill selectively connected to a whipstock. A snorkel tube is positioned within a bore of the mill and within a bore of the whipstock. The assembly is connected to drill string and positioned within an openhole portion of the wellbore. After the assembly has been anchored, cement may be pumped down the drill string and through the snorkel tube. The mill may be removed from the whipstock by shearing a shearable device connecting the mill to the whipstock. The mill is used engage a diverting surface on the whipstock and create a sidetrack. The mill may also mill a portion of the snorkel tube or the snorkel tube may be removed from wellbore up the drill string prior to milling the sidetrack.

Abstract: An optical cable includes an outer tubing. At least one optical fiber disposed within the outer tubing. A stiffening member configured to bend with bending of the outer tubing; wherein the stiffening member shifts a neutral plane of the cable away from the at least one optical fiber. Also included is a method of increasing a bending sensitivity in an optical cable.

Abstract: Methods of forming at least a portion of an earth-boring tool include providing at least one insert in a mold cavity, providing particulate matter in the mold cavity, melting a metal and a hard material to form a molten composition, and casting the molten composition. Other methods include coating at least one surface of a mold cavity with a coating material having a composition differing from a composition of the mold, melting a metal and a hard material to form a molten composition, and casting the molten composition. Articles comprising at least a portion of an earth-boring tool include at least one insert and a solidified eutectic or near-eutectic composition including a metal phase and a hard material phase. Other articles include a solidified eutectic or near-eutectic composition including a metal phase, a hard material phase and a coating material in contact with the solidified eutectic or near-eutectic composition.

Abstract: A process of managing inventory and delivery logistics of one or more chemical additives used at a well treatment site. The process includes placing one or more bulk containers at the well treatment site to maintain inventory capacity for one or more chemical additives on-site for a well treatment procedure. Monitoring chemical additive inventory within the one or more bulk containers. Making a determination, based on monitored chemical additive inventory, whether additional additive is needed in the one or more bulk containers; generating, based on the determination, initiation of an order for delivery of additional additive. delivering the additional additive in a delivery bulk container to the well treatment site. Also included is an automated additive inventory and delivery logistics control system.

Abstract: A plug counter including a housing sized to receive and pass plugs. A helix sleeve rotatably positioned relative to the housing. The helix sleeve including a helical track having a plurality of consecutive turns. A key positionable relative to the helical track and responsive to movement of the helix sleeve in a first rotational direction, wherein the key prevents further movement of the helix sleeve in the first rotational direction after a selected number of plugs pass through the plug counter.

Abstract: A well servicing fluid is disclosed. The well servicing fluid is formulated with components comprising: an organic salt, the organic salt being the product of an organic acid and an organic amine base; and an aqueous based solvent. A method of servicing a well is also disclosed.

Abstract: The migration of coal fines within a bed is reduced, inhibited or constrained by contacting the fines with nanoparticles, such as magnesium oxide crystals having an average particle size of about 30 nm. These nanoparticles may coat a proppant during the fracturing of a subterranean formation to produce methane from a coal bed therein. The nanoparticles may also treat a proppant pack in a fractured coal bed. The nanoparticles cause the coal fines to thus bind to or associate with the proppants. Thus, most of the coal fines entering fractures away from the near-wellbore region will be restrained or controlled near their origin or source and the production of methane at a desired level will be maintained much longer than a similar situation than where the nanoparticles are not used.

Abstract: Disclosed herein is a downhole plug protection system. The system includes, a tubular having perforations in a perforated portion, a screen in fluidic communication with the tubular, and a ring in sealable communication with the tubular and attached to the screen the ring having an extended portion positioned radially outwardly of the perforated portion.

Abstract: The present invention is an apparatus and method for use in a well borehole drilled into a formation. The apparatus comprises a work string disposed in the borehole. The work string includes at least one modular body portion having at least one receptacle. A modular tool is disposed in the at least one receptacle for carrying out a drilling operation. The modular tool may be a tool for use in drilling a well borehole, it may be a tool for testing a formation surrounding a borehole, or the modular tool may be a combination. For example, one aspect of the present invention provides a modular steering rib. The modular steering rib may also include modular components for sampling and testing formation fluid.

Abstract: A downhole zone isolation device is disclosed that features a non-spherical valve member that will not rotate while being drilled out. The valve member is retained in the isolation device so that flow uphole will not allow the valve member to exit the body of the isolation device. Bypass passages around the valve member are provided so that flow uphole can lift the valve member off its seat and flow can go around its periphery. Pressure from above seats the valve member. Non-metallic materials speed drill-out.

Abstract: The invention consists of a liquid end for a plunger pump, having vertical inlet and outlet, with the suction and discharge valves readily accessible for maintenance without disturbing the suction and discharge piping. The liquid end also includes a relief valve which is accessible without disturbing suction or discharge piping. The passages to and from the relief valve are internal to the housing. Inserts are provided in the valves to eliminate dead space and to facilitate the removal of any trapped air which might adversely affect the performance of the pump.
