Abstract: Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.

Abstract: A Hydraulic Manifold Control Assembly for use in connection with surface blowout preventers and diverter control systems. Said Hydraulic Manifold Control Assembly incorporates design elements and methods which reduce overall envelope dimensions, improving maintenance accessibility, thereby reducing overall installation and manufacturing time and ultimately contributing to a more robust, cost effective end-product. Said design elements and methods include: the use of intrinsically safe I/O modules and components; the employment of a removable valve assembly rack installation method; the use of a removable face plate for identification of flow control valves; the implementation of a digital automatic diverter sequence; the use of integrated manifold assemblies; and the integration of a wide-range function count.

Abstract: A latching dog includes a dog body, at least one engagement arm protrudes from an outer radial surface of the dog body in a transverse direction, and at least one retention fin protrudes from the dog body in a longitudinal direction. The at least one retention fin maintains the latching dog engaged with a housing surface to keep the latching dog at a desired axial and/or rotational position while milling the housing and latching dog.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt. % to 75 wt. % of an polyamide, from 2 wt. % to 40 wt. % of an etchable filler, from 10 wt. % to 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance to injection-molded articles that are substantially free of visual defects.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form structurally aesthetic injection-molded articles. The polyamide compositions may include from 40 wt. % to 80 wt. % of a polyamide, from 0.5 wt. % to 40 wt. % of an etchable filler, from 5 wt. % to 30 wt. % of glass fiber, optionally less than 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance and excellent mechanical properties to injection-molded articles that are substantially free of visual defects.

Abstract: Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.

Abstract: A copolyamide composition comprising a statistical copolyamide containing 70-99 wt % of diamine and dicarboxylic acid repeat units and 1-30 wt % of lactam or AA-BB repeat units, whereby incorporation of the comonomer lactam or AA-BB unit reduces the crystallization rate (longer crystallization times) while maintaining (1) high melting point, (2) low potential plate out, (3) low oxygen permeation, (4) high tensile strength and (5) puncture/tear resistance.

Abstract: A landing tool includes a body with an inner surface. A receiving groove is located on the inner surface and includes a first groove portion and a second groove portion separated by a tab. At least a portion of the tab is recessed from the inner surface of the landing tool. At least a portion of the second groove portion may further be recessed from one or both of the inner surface of the landing tool or an inner surface of the tab.

Abstract: In a process for producing a tetrabromophthalic diester composition, a liquid reaction mixture is prepared comprising tetrabromophthalic anhydride (TBPA), a C2 to C6 polyhydric aliphatic alcohol (PAA) and an alkylene oxide (AO) selected from the group consisting of ethylene oxide and propylene oxide, said reaction mixture being substantially free of an organic solvent. While agitating the reaction mixture, the temperature of the reaction mixture is raised to at least 50° C. to allow the TBPA to react with the PAA and AO to produce a diester composition. The reaction is terminated when the diester composition has an acid value equal to or less than 0.25 mg KOH/gm of the diester composition.
