Claims
- 1. An apparatus for sand-control in a subterranean well comprising:a radially expandable base pipe having an outer surface, the pipe designed for mechanically-induced permanent deformation; a radially expandable screen jacket assembly disposed about the base pipe, the screen jacket having a screen shroud; and a sand-controlling joint slidably connecting the screen shroud to the outer surface of the base pipe, the joint having longitudinally deformable slots therein.
- 2. An apparatus as in claim 1 wherein the slots run laterally about the screen shroud.
- 3. An apparatus as in claim 1 wherein the sand-controlling joint comprises a base pipe joint member attached to the base pipe and a shroud joint member attached to the screen shroud, the joint members in sand-controlling slidable engagement with one another.
- 4. An apparatus as in claim 3 wherein the longitudinally deformable slots are formed on the shroud joint member.
- 5. A method of sand-control in a subterranean well comprising the steps of:placing a radially expandable screen jacket assembly connected to a radially expandable base pipe with a longitudinally slidable sand-control joint into the well, the sand-control joint having longitudinally deformable slots therein to facilitate expansion; and mechanically radially expanding the screen jacket assembly and base pipe.
- 6. A method as in claim 5 wherein the slots are laterally oriented.
- 7. A method as in claim 5 wherein the sand-controlling joint comprises a base pipe joint member attached to the base pipe and a shroud joint member attached to the screen shroud, the joint members in sand-controlling slidable engagement with one another.
- 8. A method as in claim 7 wherein the longitudinally deformable slots are formed on the shroud joint member.
