Abstract
An apparatus that includes a chemical-injection management system. The chemical-injection management system may include a tree interface configured to couple the chemical-injection management system to a tree and a positive-displacement flow meter.
Claims24
A system, comprising:
- a chemical-injection management unit configured to regulate a fluid flow of a chemical into a wellhead, wherein the chemical-injection management unit comprises:
- a housing having an interior;
- a first interface coupled to the housing, wherein the first interface comprises a mechanical connector, a power connector, and at least one fluid connector;
- a chemical injection control assembly disposed within the interior of the housing, wherein the chemical injection control assembly is configured to control a parameter of fluid flow through a fluid path and the chemical injection control assembly comprises a valve;
- and
- a protective fluid disposed within the interior of the housing;
- and
- a pressure equalizer coupled to the housing, wherein the pressure equalizer is disposed between the protective fluid and an exterior of the chemical-injection management unit.
5 more elements
A system, comprising:
- a chemical-injection management unit configured to regulate a fluid flow of a chemical into a wellhead, wherein the chemical-injection management unit comprises:
- a housing;
- a chemical flow path through the housing from an inlet to an outlet;
- a positive displacement flow meter disposed along the chemical flow path in the housing;
- a needle valve disposed along the chemical flow path in the housing;
- an electric actuator coupled to the needle valve;
- a controller coupled to the electric actuator, wherein the controller is configured to control the needle valve based on feedback from the positive displacement flow meter without any valve position feedback relating to the needle valve.
4 more elements
A system, comprising:
- a chemical-injection management unit configured to regulate a fluid flow of a chemical into a wellhead, wherein the chemical-injection management unit comprises:
- a housing having an interior;
- a tree interface coupled to the housing, wherein the tree interface is configured to mount the housing to a tree of the wellhead;
- a remotely operated vehicle (ROV) interface coupled to the housing, wherein the ROV interface is configured to couple the housing with a remotely operated vehicle (ROV);
- a chemical injection control assembly disposed within the interior of the housing, wherein the chemical injection control assembly is configured to control a parameter of fluid flow through a fluid path, wherein the tree interface comprises a mechanical connector, a power connector, and at least one fluid connector.
