Abstract
An apparatus that is usable with a well includes a perforating system that is adapted to be fired downhole in the well. The perforating system includes a component, which includes an alloy that has a negative corrosion potential and is unable to passivate, or self-protect, while deployed in the well. The component is adapted to disintegrate to form substantially no debris in response to the firing of the perforating system.
Claims23
An apparatus usable with a well, comprising:
- a perforating system adapted to be fired downhole a well and comprising a component incorporating an alloy having a negative corrosion potential and not being able to passivate, the component adapted to disintegrate to form substantially no debris in response to the firing of the perforating system.
A method usable with a well, comprising:
- providing a perforating system downhole in the well;
- firing at least one perforating charge of the perforating system;
- and
- in response to the firing, disintegrating a component of the perforating system having an alloy having a negative corrosion potential and being unable to passivate.
