Abstract
In one aspect, an apparatus for use in a borehole includes a tubular disposed in the borehole. The apparatus also includes an expandable device disposed outside the tubular and proximate a selected device, the expandable device including a material that causes the expandable device to expand from a first shape to a second shape when exposed to an activating fluid. In addition, the expandable device reduces vibration of the selected device when the expandable device is in the second shape.
Claims21
An apparatus for use in a borehole, the apparatus comprising:
- a tubular disposed in the borehole;
- and
- an expandable device disposed outside the tubular and proximate a selected device, the expandable device comprising a material that causes the expandable device to expand from a first shape to a second shape when exposed to an activating fluid, wherein the expandable device reduces vibration of the selected device when the expandable device is in the second shape.
A method for producing fluid from a borehole, the method comprising:
- providing an expandable device configured to expand from a first shape to a second shape when exposed to an activating fluid;
- positioning the expandable device in the first shape on a tubular at a selected location in the borehole;
- and
- directing the activating fluid to the selected location to cause the expandable device to expand from the first shape to the second shape to reduce vibration experienced by equipment proximate the expandable device.
An apparatus for use in a borehole, the apparatus comprising:
- a tubular disposed in the borehole;
- and
- an expandable device disposed outside the tubular, the expandable device comprising a material that causes the expandable device to expand from a first shape to a second shape when exposed to an activating fluid, wherein the expandable device in the second shape reduces vibration experienced by equipment proximate the expandable device.
