Polymer Coated Proppant

摘要

A cross-linkable thermoplastic resin coating that is suitable for use in a coated proppant material used in sand control in oil and gas wells. The cross-linkable thermoplastic exhibits improved stability and low temperature and pressure strength compared to current thermosetting resin formulations.
