Methods and apparatus for diverting fluids either into or from a well are described. Some embodiments include a diverter conduit that is located in a bore of a tree. The invention relates especially but not exclusively to a diverter assembly connected to a wing branch of a tree. Some embodiments allow diversion of fluids out of a tree to a subsea processing apparatus followed by the return of at least some of these fluids to the tree for recovery. Alternative embodiments provide only one flowpath and do not include the return of any fluids to the tree. Some embodiments can be retro-fitted to existing trees, which can allow the performance of a new function without having to replacing the tree. Multiple diverter assembly embodiments are also described.

A device for setting and retrieving a crown plug in a well head. The device has a mandrel device, an outer housing device, a snap sleeve device downwardly protruding from the lower end of the mandrel device and a locking element. The device has an upper plug connection device and a lower plug connection device for connection to the upper connection interface and a lower plug connection device of the crown plug, respectively. An annular compartment is provided radially outside at least parts of the locking element and radially inside a lower end section of the mandrel device. An upper end of the snap sleeve device is provided axially displaceable in the annular compartment. The lower plug connection device may be configured between a locked state and an unlocked state by axial displacement of the snap sleeve device in relation to the locking element.

A technique facilitates deployment of equipment, e.g. an electric submersible pumping system, in a subsea production operation. According to an embodiment, a subsea tree assembly, e.g. a horizontal subsea tree assembly, comprises a spool body housing having a channel extending therethrough. A production receptacle structure is secured within the channel and provides a reduced internal profile for securing wellbore equipment. For example, the internal profile may be constructed to sealably receive a cable hanger used to support power cable by which an electric submersible pumping system may be suspended. The production receptacle structure also may be equipped with a production stab for interfacing with a tubing hanger located below the production receptacle structure.

An apparatus for effecting injection of fluids into a subsea horizontal tree includes a fluid injection tree cap having a body with a bore extending therethrough so as to open at one end to a top of the body. An isolation valve is cooperative with the bore of the body so as to open or close fluid flow through the bore. The fluid injection tree cap is connected to the horizontal subsea tree. The horizontal subsea tree has only a single crown plug therein. The bore of the fluid injection tree cap communicates with an annulus of the horizontal subsea tree. The horizontal subsea tree has valving therein so as to selectively direct fluid from the bore of the tree cap to the annulus of the well or to the horizontal subsea tree.

Connector for fluid, connectable by a remotely operated vehicle, ROV, includes a first part including a first cam element including an opening and a cam for engagement of a protrusion, the first cam element and the cam being rotably arranged relative to the first part; a second part includes a second cam element for insertion into the opening, the second cam element including the protrusion for the cam; a clutch between the first cam element and a handle to be held by the ROV; an indicator on the first part to indicate correct position for connecting, and disconnecting, the first part with, or from, the second part with the first and second cam elements; and an emergency release mechanism to disconnect the first part from the second part.
