17. A well completion method comprising:
covering at least one base pipe with an elastomer alloy, wherein the elastomer alloy comprises:
a base polymer comprising hydrogenated nitrile butadiene rubber (HNBR);
at least one secondary polymer selected from the group consisting of low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE), wherein the base polymer and the at least one secondary polymer are blended into a polymer matrix;
a plurality of smart fillers dispersed within the polymer matrix;
at least one chemical foaming agent; and
a curing activator;
compressing the elastomer alloy with a mechanical retainer;
running the at least one base pipe to a location in a wellbore;
expanding the elastomer alloy;
conforming the elastomer alloy to a wall of the wellbore;
filtering fluids through the elastomer alloy to the at least one base pipe;
detaching the elastomer alloy from the at least one base pipe; and
lifting the at least one base pipe out of the wellbore.
