Fiber optic monitoring in chemical injection and gas lift systems
A wellhead, including a fluid injection system disposed in the wellhead, a fiber injection system disposed in the wellhead and operably connected to the fluid injection system to inject fiber into the fluid injection system. A multimodal fluid injection valve, including a body having a check valve therein, a side pocket physically and fluidly connected to the body, the side pocket including a fiber anchor therein. A method for instrumenting a preexisting gas lift or chemical injection system, including cleaning the chemical injection system, and injecting optic fiber through the chemical injection system. A wellbore system including a borehole in a subsurface formation, a string in the borehole, a surface system operably connecting both a chemical or gas injection device and an optic fiber injection device to a gas lift or chemical injection subsystem in the borehole, and an optic fiber disposed in the chemical or gas injection subsystem.
1 . A wellbore system, comprising:
a wellhead housing;
a fluid injection system operably connected to the wellhead housing;
a fiber injection system operably connected to the wellhead housing and operably connected to the fluid injection system to inject bare fiber into the fluid injection system; and
a multimodal fluid injection valve, comprising:
a body having a check valve therein;
a side pocket entirely within the body, the side pocket including a fiber anchor comprising a landing nipple cartridge configured to receive a landing nipple that terminates an optic fiber.
2 . The wellbore system as claimed in claim 1 , wherein the fiber injection system includes a fiber header.
3 . The wellbore system as claimed in claim 1 , wherein the fluid injection system is a chemical injection system.
4 . The wellbore system as claimed in claim 1 , wherein the fluid injection system is a gas lift injection system.
5 . A multimodal fluid injection valve, comprising:
a body having a check valve therein;
a side pocket entirely with the body the side pocket including a fiber anchor comprising a landing nipple cartridge configured to receive a landing nipple that terminates an optic fiber.
6 . The valve as claimed in claim 5 , wherein the body further includes a burst disk.
7 . The valve as claimed in claim 5 , wherein the fiber anchor includes a magnetically permeable material.
8 . The valve as claimed in claim 5 , wherein the fiber anchor includes a magnet.
9 . A wellbore system comprising:
a borehole in a subsurface formation;
a string in the borehole;
a surface system operably connecting both a chemical or gas injection device and an optic fiber injection device to a gas lift or chemical injection subsystem in the borehole; and
a bare optic fiber disposed in the chemical or gas injection subsystem; and
a multimodal fluid injection valve, comprising:
a body having a check valve therein;
a side pocket entirely within the body, the side pocket including a fiber anchor comprising a landing nipple cartridge configured to receive a landing nipple that terminates an optic fiber.
