ABSTRACT:
Methods of making and using wellbore casing are described, one method comprising providing a plurality of flow-through passages in a portion of a casing while the casing is out of hole; temporarily plugging the flow-through passages with a composition while out of hole; running the casing in hole in a wellbore intersecting a hydrocarbon-bearing formation; and exposing the composition to conditions sufficient to displace the composition from the flow-through passages while in hole. Methods of using the casing may include pumping a stimulation treatment fluid through the casing string and into a formation through the flow-through passages in the first casing joint; plugging the flow-through passages in the first casing section; and exposing a second casing joint of the casing string to conditions sufficient to displace the composition from the flow-through passages in the second casing joint.
