Abstract: A well configuration unit configured to connect to a zipper manifold, and comprising a bridge connector header comprising an axial throughbore and a horizontal throughbore. A frac manifold connector is connected to the axial throughbore of the bridge connector header and comprises a mandrel that is axially movable and a hydraulic setting tool configured to move the mandrel from an open position, in which fracturing fluid is allowed to flow from the zipper manifold to a connected frac tree, to a closed position, in which the mandrel and its associated cup tool prevent fracturing fluid from flowing to the connected frac tree. A bridge connector is connected to the horizontal throughbore of the bridge connector header and comprises two bridge spools configured to connect the zipper manifold to the same frac tree.

Abstract: A universal atmospheric deployment device (“UADD”) for use in oil and gas production or similar applications is provided. In one embodiment, the UADD includes a number of storage carriers disposed around a pathway that can be deployed into a well bore. The figures and art described herein show that this novel feature can increase the speed and usefulness of dispatching tools down a well bore, and also decrease down time to install or retrieve these devices. This UADD also removes personnel from the hazardous area, allowing for remote deployment of tools and devices.

Abstract: An extendable spool is disclosed. The length of the extendable spool is able to continuously varied. The extendable spool accounts for length variances in flow lines by extending the flow line rather than redirecting the flow. Because the flow direction does not make any turns, erosion is minimized on both the extendable spool and downstream parts. The extendable spool is readily scalable from small diameters to large diameters. Because of this, it requires fewer lines and therefore less setup time to account for length differences between large diameter lines.

The figures and art described herein show that this novel feature can increase the ability of the valve to seal in high-pressure environments, and also increase the reliability of the valve when in cycling use.

Abstract: A frac zipper manifold bridge connector comprises two bridge spools for connecting a well configuration unit of a frac zipper manifold to a frac tree of a wellhead. The connector comprises multiple connections involving threaded flanges, such that the orientation of the bridge spools may be adjusted to ensure that they are correctly aligned with the frac tree.

Abstract: A reciprocating plunger pump fluid end having increased material thicknesses in typical high stress concentration areas includes locating valves in spherically segmented shaped suction and discharge bores adjacent to chamfered transition areas to provide for reduced stress concentrations, resistance to fatigue failure and erosion and ease of access for maintenance. Among other features the housing includes a valve retainer assembly integrally mounted inside the housing which includes a profile to reduce stresses in the bores and facilitate access for replacement of internal components.

Abstract: A process for making betahydroxyaldehydes such as 3-hydroxypropanal which comprises intimately contacting (a) an oxirane, (b) carbon monoxide, (c) a reducing agent such as hydrogen, (d) from about 0.01 to about 1 weight percent, basis cobalt metal, of a cobalt hydroformylation catalyst which is optionally complexed with a tertiary phosphine ligand, and (e) a heterogeneous, preferably solid, metal promoter used at a molar ratio of 0.05, preferably 0.15, to 100 moles of heterogeneous metal relative to the moles of soluble cobalt hydroformylation catalyst.

C. and separating the aqueous phase containing 3-hydroxypropanal from the organic phase containing cobalt catalyst; hydrogenating the 3-hydroxypropanal in the aqueous phase to 1,3-propanediol; and recovering the 1,3-propanediol.The process enables the production of 1,3-propanediol in high yield and selectivity without the use of a phosphine ligand-modified cobalt catalyst.

Abstract: 1,3-propanediol is prepared in a process which involves hydroformylating ethylene oxide:(a) in an essentially non-water-miscible solvent in the presence of a non-ligated cobalt catalyst and a catalyst promoter at a temperature within the range of about 50.degree. to about 100.degree. C. and a pressure within the range of about 500 to about 5000 psig, to produce an intermediate product mixture comprising less than about 15 wt % 3-hydroxypropanal;(b) adding an aqueous liquid and extracting at a temperature less than about 100.degree. C. the 3-hydroxypropanal to provide an aqueous phase comprising 3-hydroxypropanal in greater concentration than the concentration of 3-hydroxypropanal in said intermediate product mixture, and an organic phase comprising the cobalt catalyst;(c) separating the aqueous phase from the organic phase;(d) hydrogenating the 3-hydroxypropanal to provide a hydrogenation product mixture comprising 1,3-propanediol; and(e) recovering 1,3-propanediol from said hydrogenation product mixture.

Abstract: 1,3-propanediol is prepared in a process in which ethylene oxide is reacted with carbon monoxide and hydrogen in an essentially non-water-miscible solvent in the presence of an effective amount of a non-phosphine-ligated cobalt catalyst and an effective amount of a catalyst promoter under reaction conditions effective to produce an intermediate product mixture comprising less than about 15 wt % 3-hydroxypropanal. The 3-hydroxypropanal is extracted in water from the product mixture in more concentrated form, with the majority of the cobalt catalyst remaining in the solvent phase for recycle to the hydroformylation reaction. At least a portion of any residual catalyst in the water phase following extraction is removed by re-extraction with non-water-miscible solvent and recycled to hydroformylation. The 3-hydroxypropanal is then hydrogenated in aqueous solution to the desired 1,3-propanediol.
