Abstract: A spatially positioned assembly comprising, in preferred embodiments, a fluid inlet in fluid flow communication with a fluid connection adapter. A plurality of boom sections are concatenated in articulated fashion. The plurality is rotatably connected to a turret at a proximal thereof, and is rotatably connected with the fluid connection adapter at a distal end thereof. The fluid connection adapter is disposed for connection to a mating fluid connection housing assembly provided on a wellhead. Independent control of rotation at multiple axes on the spatially positioned assembly allows an operator to establish measured directional bearings at axes, such that sets of measured directional bearings values contribute to defining corresponding spatial positions for the assembly.

Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. Disclosed embodiments gain advantage from the internal work pressure to provide improved seal performance. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) at least a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring upon the locking elements urges the locking elements to tighten against the adapter. Internal pressure encourages adapter displacement, which then further tightens the adapter against the locking elements as now restrained by the locking ring. Internal pressure further encourages the first seal section on the adapter to expand radially to tighten the contact with the first seal bore in the housing assembly.

Abstract: A fluid delivery system including an articulated fluid delivery unit (FDU) comprising, in preferred embodiments, first and second boom sections concatenated in articulated fashion to a turret. A stinger assembly is provided at a distal end of the FDU. The stinger assembly includes a fluid connection adapter for connection to a mating fluid connection housing assembly provided on a wellhead. Independent control of rotation at each of multiple axes on the FDU allows an operator to establish a measured directional bearing at each axis, such that a set of directional bearings values defines the FDU's current spatial position. In preferred embodiments, the FDU may “learn” a desired spatial position by storing the set of directional bearings values corresponding to that spatial position. The FDU may then return to that stored spatial position robotically when instructed to recall and take up again the corresponding set of directional bearings values.

Abstract: A solids separator includes a housing having a fluid inlet, the fluid inlet oriented to induce helical flow of fluid entering the housing. A flow reversing device is disposed within the housing and is arranged to reverse a longitudinal direction of the helical flow within the housing. A fluid outlet is disposed at an upper end of the housing. The fluid outlet includes within its cross-section a radial center of the housing.

Abstract: A remote operator interface and control unit configured to monitor status of, and control over, fluid connections at wellheads. Independent and concurrent status monitoring and control communication with fluid connections is provided at each of a plurality of wells. The operator interface and control unit allows a remote operator to lock and unlock fluid connection assemblies on wellheads, while at the same time viewing wellhead conditions accompanying such actions.
