Abstract
A downhole assembly includes a disintegrable article, which contains a polymer matrix comprising a polymer having an oxygen content of about 2 wt % to about 30 wt %; an energetic material configured to generate heat upon activation to facilitate a chemical decomposition of the polymer; and at least one of a reinforcing fiber or a filler. The disintegrable article is disintegrated by disposing the downhole assembly in a downhole environment; performing a downhole operation; exposing the polymer in the polymer matrix to the generated heat to chemically decompose the polymer producing a decomposed product containing a small molecule in a supercritical state; and disintegrating the disintegrable article with the small molecule in the supercritical state.
