Downhole modular Y-tool
View Patent ↗A Y-tool for use in a wellbore includes: a stem having a bore formed therethrough, a port formed through a wall thereof, and a coupling formed at each end thereof; a branch fastened to the stem and having a passage formed therethrough in fluid communication with the stem port and a coupling formed at an end thereof; and a gasket sealing an interface of the stem port and branch passage.
1. A Y-tool, comprising:
a stem having a bore formed therethrough, a port formed through a wall thereof, and a coupling formed at each end thereof;
a branch fastened to the stem and having a passage formed therethrough in fluid communication with the stem port and a coupling formed at an end thereof; and
a gasket sealing an interface of the stem port and branch passage, wherein the Y-tool is configured to be disposed in a wellbore.
2. The tool of claim 1 , wherein the stem has a mounting shoulder and the branch is seated on the mounting shoulder.
3. The tool of claim 2 , wherein the mounting shoulder and the branch each have a profile and the profiles are engaged.
4. The tool of claim 1 , wherein the couplings are threaded.
5. The tool of claim 1 , further comprising an electronics package disposed in a cavity formed in the stem.
6. The tool of claim 5 , further comprising a proximity sensor disposed in an inner surface of the stem and in electrical communication with the electronics package.
7. An artificial lift system (ALS) for use in a wellbore, comprising:
the Y-tool of claim 1 ; and
an electric submersible pump (ESP) connected to the branch.
8. The ALS of claim 7 , further comprising:
bypass tubing connected to the stem; and
a clamp, comprising:
a mandrel torsionally connected to the ESP and having splines formed along an outer surface thereof;
a splined sleeve disposed on the mandrel;
a sleeve torsionally connected to the bypass tubing; and
a bracket torsionally connecting the splined sleeve to the bypass sleeve.
9. An assembly, comprising:
the Y-tool of claim 5 ; and
a Venturi tube connected to the branch,
wherein the Y-tool further comprises a differential pressure sensor in fluid communication with the Venturi tube and in electrical communication with the electronics package.
10. The tool of claim 5 , wherein:
the stem has an injection passage formed therethrough, and
the Y-tool further comprises one or more sensors in fluid communication with the injection passage and in electrical communication with the electronics package.
11. An assembly, comprising:
the Y-tool of claim 10 ; and
a landing nipple connected to the stem and having a port formed through a wall thereof in fluid communication with the injection passage.
