Patent ID: 7451815

Claim:
A sand control screen assembly for use in a wellbore, comprising: a tubular base pipe having a first perforated section, the first perforated section having at least a first opening that allows fluid flow therethrough; an internal seal element disposed within an internal diameter of the tubular base pipe and positioned at least partially overlapping the first perforated section, the internal seal element able to control fluid flow through the first opening; wherein the internal seal element is configured to allow fluid flow from an exterior of the tubular base pipe through the first opening when an exterior fluid pressure is sufficiently higher than an internal fluid pressure; wherein the internal seal element includes a first material that is dissolvable by a first solvent, and wherein the internal seal element may be dissolved by exposing the internal seal element to the first solvent until the internal seal element no longer controls fluid flow through the first opening; the tubular base pipe having a second perforated section, the second perforated section having at least a second opening; a degradable plug disposed so as to prevent fluid flow through the second opening; and wherein the degradable plug includes a second material that is dissolvable by a second solvent, and wherein the degradable plug may be dissolved by exposing the degradable plug to the second solvent until the degradable plug no longer prevents fluid flow through the second opening.
