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 diverter assembly for a manifold of an oil or gas well, the manifold having a production bore and a wing branch communicating with the production bore, comprising a housing disposed on the wing branch and having an internal passage, wherein the diverter assembly comprises a first path in a first direction to divert flow of a fluid from the wing branch of the manifold or from a flowline communicating with the wing branch, and a second path in a second direction to return flow of the fluid to the other of the wing branch or the flowline, wherein the first and second paths are coaxial paths not passing through the production bore and the first direction is opposite to the second direction.
