Abstract
Embodiments disclose a sand screen apparatus for use in a well that intersects a hydrocarbon formation. The sand screen apparatus comprises a composite, the composite having a compressed state and an expanded state. In embodiments, the composite comprises a base polymer and one or a plurality of reactive fillers where the reactive fillers react with the base polymer in the expanded state after exposure to a first trigger.
Claims26
A sand screen apparatus for use in a well that intersects a hydrocarbon formation, comprising:
- a composite, the composite having a compressed state and an expanded state;
- the composite comprising a base polymer, one or a plurality of reactive fillers, and a plurality of dissolvable or degradable fillers dispersed within the composite;
- wherein the one or the plurality of reactive fillers react with the base polymer in the expanded state after exposure to a first trigger.
A well completion method, comprising:
- covering at least one base pipe with a composite comprising a base polymer and one or a plurality of reactive fillers;
- running the base pipe to a location in a wellbore;
- expanding the composite;
- conforming the composite to the wellbore wall;
- stiffening the composite;
- and
- filtering fluids through the composite to said base pipe;
- detaching the composite from the base pipe;
- and
- lifting the base pipe out of the wellbore.
A method of completing a wellbore in a subterranean formation, comprising:
- positioning an expandable sand control device in the wellbore and forming an annulus between the sand control device and the wellbore, the sand control device having a foam composite comprising a base polymer, one or a plurality of reactive fillers, and a plurality of dissolvable or degradable fillers dispersed within the composite, the foam composite designed to expand and fill the annulus.
