Lightweight composite particulates and methods of using such particulates in subterranean applications

摘要

The present invention relates to lightweight composite particulates and their use in subterranean applications such as production enhancement and completion. One embodiment of the present invention provides a method of forming a lightweight particulate suitable for use as proppant or gravel in a subterranean operation comprising the steps of forming a substantially homogeneous mixture of PET and a filler material; forming the homogeneous mixture into particulates suitable for use in a subterranean environment. Other embodiments of the present invention provide methods of treating, fracturing, and gravel packing a chosen zone in a subterranean formation.
