Apparatus and method for recovering fluids from a well and/or injecting fluids into a well
First Claim
1. A system, comprising:
- a diverter assembly for a manifold of an oil or gas well, wherein the diverter assembly comprises a housing with an internal passage, and the diverter assembly is adapted to connect to a branch of the manifold;
a pump adapted to fit within a bore of the manifold; and
wherein the diverter assembly is adapted to divert fluids from a first portion of a first flowpath to a second flowpath, and to divert the fluids from the second flowpath to a second portion of the first flowpath.

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 retrofitted 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.
