Abstract
A safety valve for use in a subterranean well can include a housing assembly having a flow passage extending longitudinally through the housing assembly. An outer diameter of the housing assembly is eccentric relative to the flow passage. A well tool can include a magnetic coupling between magnet devices. One magnet device includes a series of magnets which are unequally spaced circumferentially about the other magnet device. Another safety valve can include a longitudinally extending flow passage, a closure device which selectively permits and prevents flow through the flow passage, and an outer diameter which is eccentric relative to the flow passage.
Claims15
A safety valve for use in a subterranean well, the safety valve comprising:
- a housing assembly having a flow passage extending longitudinally through the housing assembly;
- and
- wherein an outer diameter of the housing assembly is eccentric relative to the flow passage, wherein the housing assembly has a thickened wall section due to the outer diameter being eccentric relative to the flow passage, and wherein at least one position sensor is positioned in the thickened wall section.
A safety valve for use in a subterranean well, the safety valve comprising:
- a housing assembly having a flow passage extending longitudinally through the housing assembly;
- and
- wherein an outer diameter of the housing assembly is eccentric relative to the flow passage, wherein the housing assembly has a thickened wall section due to the outer diameter being eccentric relative to the flow passage, and wherein an electrical actuator displaces a magnet against a biasing force exerted by a biasing device, each of the electrical actuator, magnet and biasing device being positioned in the thickened wall section.
A safety valve, comprising:
- a longitudinally extending flow passage;
- a closure device which selectively permits and prevents flow through the flow passage;
- an outer diameter which is eccentric relative to the flow passage;
- and
- a thickened wall section due to the outer diameter being eccentric relative to the flow passage, wherein at least one magnet is positioned in the thickened wall section.
