Abstract
Techniques and systems to provide pressure reduction of a fluid, for example, from a well. A device includes an input configured to be fluidly coupled to a well control device. The device also includes an output configured to be to be fluidly coupled to the well control device. The device further includes at least one valve configured to alter a pressure of a fluid received at the input and transmitted from the output.
Claims20
A device, comprising:
- a first input, that when in operation, is fluidly coupled to a choke line associated with a well control device;
- a first output, that when in operation, is fluidly coupled to the choke line associated with the well control device;
- a second input, that when in operation, is fluidly coupled to a kill line, wherein the kill line is associated with the well control device and operated in parallel with the choke line to remove an influx from a well;
- a second output, that when in operation, is fluidly coupled to the kill line associated with the well control device;
- at least one first valve, that when in operation, alters a pressure of a first fluid received at the first input and transmitted from the first output to remove the first fluid from a well;
- and
- at least one second valve, that when in operation, alters a pressure of a second fluid received at the second input and transmitted from the second output to remove the second fluid from the well.

A system, comprising:
- a subsea pressure reducing module comprising:
- a first input that when coupled to a choke line receives a fluid having a first pressure from a first portion of the choke line associated with a first portion of a well control device;
- a second input that when coupled to a kill line receives a second fluid having the first pressure from a first portion of the kill line, wherein the kill line is associated with the first portion of the well control device and operated in parallel with the choke line to remove an influx from a well;
- first pressure adjustment componentry coupled to the first input and configured to adjust the first pressure of the first fluid to a second pressure;
- second pressure adjustment componentry coupled to the second input and configured to adjust the first pressure of the second fluid to the second pressure;
- a first output coupled to the first pressure adjustment componentry and when coupled to a second portion of the choke line transmits the first fluid having the second pressure to the second portion of the choke line associated with a second portion of the well control device;
- and
- a second output coupled to the second pressure adjustment componentry and when coupled to a second portion of the kill line transmits the second fluid having the second pressure to the second portion of the kill line associated with the second portion of the well control device;
- and
- a control system configured to be coupled to the subsea pressure reducing module to monitor the operation of the subsea pressure reducing module.
7 more elements
A system, comprising:
- a conduit, that when in operation, is fluidly coupled to a drill pipe to receive a fluid transmitted from an offshore platform via the drill pipe, the fluid having a first pressure of up to at least 20,000 psi, wherein the conduit comprises an output to transmit the fluid having the first pressure;
- and
- a subsea pressure reducing module, that when in operation, is coupled to the conduit, wherein the subsea pressure reducing module comprises:
- an input that when coupled to the conduit receives the fluid having the first pressure;
- pressure adjustment componentry coupled to the input and configured to adjust the fluid having the first pressure to the fluid having a second pressure;
- and
- an output coupled to the pressure adjustment componentry and when coupled to a first portion of a blowout preventer transmits the fluid having the second pressure to a first portion of a blowout preventer;
- wherein the second pressure is less than the first pressure.
