Apparatus and method for recovering fluids from a well and/or injecting fluids into a well
First Claim
1. A tree assembly including a subsea tree with a production bore and a lateral production port communicating with the production bore, the tree assembly comprising:
- a pipework with;
a first fluid flowpath communicating with the lateral production port,a second fluid flowpath communicating with an end port of the pipework, the pipework including;
a first subsea-accessible port communicating with the first fluid flowpath, anda second subsea-accessible port communicating with the second fluid flowpath such that the pipework is communicating between the lateral production port and the end port, the pipework having the first and second fluid flowpaths and the first and second subsea-accessible ports therebetween, anda flow processing module with a processing apparatus communicating with the first and second fluid flowpaths.

Abstract
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.

25. A tree assembly, comprising:
-
a subsea tree with a production bore and a lateral production port communicating with the production bore; a pipework with a first fluid flowpath communicating with the lateral production port, a second fluid flowpath communicating with an end port of the pipework, a first subsea-accessible port communicating with the first fluid flowpath and a second subsea-accessible port communicating with the second fluid flowpath; and a flow processing module comprising a choke and a flow measuring device, and communicating with the first and second fluid flow paths; wherein the tree assembly includes a tree fluid flow path from the lateral production port, through the choke and measuring device, and to the end port.
