Apparatus and method for recovering fluids from a well and/or injecting fluids into a well

A diverter assembly disposed on a lateral branch of a tree to access flow, the lateral branch having a lateral branch bore communicating with a tree production bore and an outlet connected to an export line with an export line bore, comprising:

• a choke body in use disposed on the lateral branch of the tree between the tree production bore and export line bore, the choke body comprising:
• a lateral branch passage in fluid communication in use with the lateral branch bore and tree production bore;
• an export line passage in fluid communication in use with the export line bore;
• and
• a choke insert passage adapted to receive a choke insert of a choke;
• and
• the choke insert passage forming a fluid flow path therethrough to flow fluids in use through the choke insert passage into either the lateral branch passage or the export line passage or from either the lateral branch passage or the export line passage.

A diverter assembly disposed on a lateral branch of a tree to access flow, the lateral branch having a lateral branch bore communicating with a tree production bore and an outlet connected to an export line with an export line bore, comprising:

• a choke body in use disposed on the lateral branch of the tree between the tree production bore and export line bore, the choke body comprising:
• a lateral branch passage in fluid communication in use with the lateral branch bore and tree production bore;
• an export line passage in fluid communication in use with the export line bore;
• and
• a choke insert passage adapted to receive a choke insert of a choke;
• and
• a choke having a flow passage therethrough, the choke flow passage and choke insert passage forming a fluid flow path to flow fluids in use through the choke flow passage into either the lateral branch passage or the export line passage or from either the lateral branch passage or the export line passage.

A diverter assembly for injecting fluids through a lateral branch of a tree or an export line connected to the lateral branch, a choke body being disposed between the lateral branch and export line, comprising:

• a choke coupled to the top of the choke body;
• the choke having an inlet passage and an outlet passage;
• the inlet passage or outlet passage being connected to a processing apparatus;
• and
• the other of the inlet passage or outlet passage being in fluid communication with the lateral branch and/or export line.

A diverter assembly for a production tree having a tree body with a bore and a lateral production port extending from the bore, comprising:

• a wing branch extending from the tree and comprising a horizontal bore aligned with the lateral production port and a vertical bore extending from the horizontal bore;
• the wing branch comprising a production wing valve that is located between the tree body and the vertical bore;
• and
• a choke disposed on an end of the wing branch.

A method of diverting fluid from a production bore of a subsea production tree, the method comprising:

• connecting a choke body to a lateral branch of the tree;
• communicating a lateral branch passage of the choke body to a lateral branch bore of the lateral branch;
• communicating an export line passage of the choke body to an export line bore of an export line;
• and
• flowing fluid through a choke insert passage in the choke body into either the lateral branch passage or the export line passage or from either the lateral branch passage or the export line passage.
