Sand Control Screen Assembly Having a Surface-Modified Filter Medium and Method for Making Same

摘要

A sand control screen assembly (100) positionable within a wellbore (26) for filtering particulate matter out of production fluids. The sand control screen assembly (100) includes a perforated base pipe (102) that allows fluid flow therethrough and a filter medium (124) disposed exteriorly about the base pipe (102). A surface-modified agent is disposed on at least a portion of the filter medium (124). The surface-modified agent is operable to enhance the surface filter characteristics of the filter medium (124), thereby reducing particulate infiltration into the filter medium (124).
