A fluid manifold connector apparatus includes a stinger having fluid channels for receiving fluid from flow lines and discharging the fluid through axially-spaced outlet ports on the stinger, plus a receiver having a bore with inlet ports spaced to match the stinger outlet ports. Annular seals are provided above and below each stinger fluid outlet port, or above and below each receiver fluid inlet port, to form a sealed annular fluid chamber between each axially-adjacent pair of seals when the stinger is disposed within the receiver bore. The flow lines pass through bores in a deformable plug disposed within the bore of a stinger extension sleeve for fluid communication with the upper ends of the stinger fluid channels. A piston assembly is mountable to the sleeve for compressing and deforming the plug to sealingly grip the flow lines and to seal the plug against the bottom of the sleeve bore.

An axisymmetric clutch mechanism includes a drive clutch body having a drive bearing surface and a drive clutch surface; an intermediate clutch body having an intermediate clutch surface configured for sliding contacting engagement with the drive clutch surface; a driven clutch body having a driven bearing surface configured for transferring compressive axial force to the drive bearing surface; and rotational drag means for generating resistance to rotational slippage between the drive clutch surface and the intermediate clutch surface. The intermediate and driven clutch bodies are helically coupled in a first rotational direction, forming a first helical coupling having a first lead angle, and with the taper angle of the drive clutch surface and the intermediate clutch surfaces and the first lead angle being selected such that the clutch mechanism will lock when the drive clutch body is rotated relative to the driven clutch body in the first rotational direction.

Clutch mechanism for gripping tools

A clamp assembly, for mounting around a tool joint coaxially joining cylindrical upper and lower workpieces, comprises an upper collar assembly and a lower collar assembly, each having semi-cylindrical left and right collar segments. The left and right collar segments of each collar assembly are removably connectable to each other by threaded fasteners to form the collar assembly. The upper and lower collar assemblies are coaxially mountable around the upper and lower workpieces, respectively, such that tightening the fasteners will urge the upper and lower collar assemblies to grip the upper and lower workpieces, respectively, and thus to provide increased resistance to relative rotation between the two workpieces about the tool joint axis. The upper and lower left collar segments, and/or the upper and lower right collar segments, may be interlockingly and radially slidable relative to each other to accommodate differences between the outside diameters of the two workpieces.

A system for optimizing a tubular running operation (TRO) in which a running string is disposed in a wellbore includes sensors located at the wellsite, plus one or more processors, displays, and user-input devices, which may be at the wellsite or elsewhere. The sensors are configured to measure running string parameters including the running strings position within the well, the running and rotation rates, and loads acting at the top of the running string. Based on this information, the processor(s) perform torque-and-drag analysis (TDA) in the top-down direction to estimate downhole loads on user-selected running string components, accounting for measurement and modelling uncertainties. Based on the estimated loads, the processor(s) calculate one or more damage indicators, which are communicated to the user via the display(s), enabling the user to take corrective action to prevent or manage damage to the running string.

System and method for optimizing tubular running operations using real-time measurements and modelling

A collet-type mechanism for releasably gripping either an external or internal target surface of a tubular workpiece includes a collet receiver defining a collet receiver contact surface configured as a curved lateral surface of a truncated right circular cone, and a segmented collet assembly comprising a plurality of collet segments. Each collet segment defines a workpiece engagement surface configured for gripping engagement with a workpiece target surface, and a collet segment contact surface configured for at least partial contacting engagement with the collet receiver contact surface. The collet segment contact surface may comprise two axially-contiguous regions, one of which corresponds to a curved lateral surface of either an oblique circular cylinder or a right circular cylinder, and the other of which corresponds to a curved lateral surface of a truncated right circular cone.

Apparatus and methods for improving contact stress distribution within collet-type mechanisms

An adjustable-length bail extension includes a tubular outer link member, an inner link member axially movable within the bore of the outer member, and an adjustment mechanism for releasably clamping the outer member to the inner member at any of multiple locking positions defined by sets of locking grooves formed at axial intervals on the inner member. The adjustment mechanism is operable between a locked position wherein a collet assembly linked to the outer member engages a selected locking groove set and thereby enables axial load transfer between the inner and outer members; and an unlocked position wherein the collet assembly does not lockingly engage any locking grooves, such that the inner member is axially movable within the outer member to enable adjustment of the overall length of the adjustable-length bail extension by repositioning the collet assembly to engage the inner member at a different locking position.
