Abstract
A method for controlling sand production in a well drilled in a subterranean formation comprising installing an expandable sand screen assembly in the well. The expandable sand screen assembly comprises an expandable sand screen in an unexpanded configuration. A slurry is pumped down the well and circulated through the annular space defined by the expandable sand screen and the formation. The expandable sand screen is expanded thereby dehydrating the slurry in the annular space.
Claims13
A method for controlling sand production in a well drilled in a subterranean formation comprising:
- a) installing an expandable sand screen assembly comprising an expandable sand screen in an unexpanded configuration into the well;
- b) pumping a slurry down the well;
- c) circulating the slurry through an annular space defined by the expandable sand screen and the formation;
- and
- d) expanding the expandable sand screen and thereby dehydrating the slurry in the annular space.
A sand control system comprising:
- a well drilled in a formation;
- an expandable sand screen installed in the well in an expanded configuration;
- an annular space located between the outer surface of the expandable sand screen and the formation;
- and
- a gravel pack located in the annular space;
- wherein the gravel pack was dehydrated by expanding the expandable sand screen.
A method for producing oil or gas comprising:
- a) drilling a well in a subterranean formation comprising:
- b) installing an expandable sand screen assembly comprising an expandable sand screen in an unexpanded configuration into the well;
- c) pumping a slurry down the well;
- d) circulating the slurry through an annular space defined by the expandable sand screen and the formation;
- e) expanding the expandable sand screen thereby dehydrating the slurry in the annular space;
- and
- f) producing oil or gas from the well.
