Connection system for subsea flow interface equipment
A connection system for connecting flow interface equipment to a subsea manifold is disclosed. The connection system relates particularly to a connection apparatus adapted to land a conduit means on a subsea manifold in a first stage of the connection and to connect a conduit means of the connection apparatus to a choke body of the manifold in a second stage of the connection.
1. An assembly for injecting fluids into a subea well having a flow bore extending through a tree and into the well, the tree including a lateral branch with a branch bore communicating with the flow bore, the assembly comprising:
a choke body mounted on the lateral branch of the tree and communicating with the well flow bore, the choke body having fluid communication with a processing apparatus; and
a single path injection flowpath extending from the processing apparatus through the choke body and into the branch bore to inject fluids into the well flow bore.
2. The assembly of claim 1 wherein the fluids include water from the sea.
3. The assembly of claim 1 wherein the fluids are chemicals.
4. The flow diverter assembly of claim 1 wherein the processing apparatus is selected from the group consisting of at least one of a pump, process fluid turbine, injection apparatus, chemical injection apparatus, fluid riser, measurement apparatus, temperature measurement apparatus, flow rate measurement apparatus, constitution measurement apparatus, consistency measurement apparatus, gas separation apparatus, water separation apparatus, solids separation apparatus, water electrolysis apparatus, and hydrocarbon separation apparatus.
5. The assembly of claim 1 wherein the processing apparatus is a chemical injection apparatus.
6. The assembly of claim 1 wherein the processing apparatus communicates with one end of a mandrel and the mandrel having another end connected to a connector on the choke body.
7. The assembly of claim 1 further including a conduit extending between the processing apparatus and a manifold connected to a connector on the choke body.
8. An assembly for injecting chemicals into a well having a flow bore extending through a tree and into the well, the tree including a lateral branch with a branch bore communicating with the flow bore, the assembly comprising:
a chemical injection apparatus communicating via a conduit with the branch bore; and a single path injection flowpath extending from the chemical injection apparatus through the conduit and into the branch bore and well flow bore to inject chemicals into the well flow bore;
wherein the branch bore includes an outlet connected to a flowline, the outlet being closed during injection.
9. The assembly of claim 8 further including a closure member to close the outlet.
10. An assembly for injection of fluids into a well having a flow bore extending through a tree and into the well, comprising:
a branch on the tree, the branch communicating with the flow bore and having an outlet and the branch including a port through a wall thereof;
a conduit communicating with the port to form a single path injection flowpath extending from an apparatus and through the wall of the branch and into the flow bore to inject into the flow bore; and
a closure member for opening and closing the outlet of the branch; wherein the fluids are chemicals.
11. An assembly for injection of fluids into a well having a flow bore extending through a tree and into the well, comprising:
a branch on the tree, the branch communicating with the flow bore and having an outlet and the branch including a port through a wall thereof;
a conduit communicating with the port to form a single path injection flowpath extending from an apparatus and through the wall of the branch and into the flow bore to inject into the flow bore; and
a closure member for opening and closing the outlet of the branch;
wherein the apparatus is selected from the group consisting of at least one of a pump, process fluid turbine, injection apparatus, chemical injection apparatus, fluid riser, measurement apparatus, temperature measurement apparatus, flow rate measurement apparatus, constitution measurement apparatus, consistency measurement apparatus, gas separation apparatus, water separation apparatus, solids separation apparatus, water electrolysis apparatus, and hydrocarbon separation apparatus.
12. An assembly for injection of fluids into a well having a flow bore extending through a tree and into the well, comprising:
a branch on the tree, the branch communicating with the flow bore and having an outlet and the branch including a port through a wall thereof;
a conduit communicating with the port to form a single path injection flowpath extending from an apparatus and through the wail of the branch and into the flow bore to inject into the flow bore; and
a closure member for opening and closing the outlet of the branch;
wherein the apparatus is a chemical injection apparatus.
