Abstract
A rigless sand-control tool string is for use in a wellbore having plural zones. The tool string includes plural flow port assemblies, and plural screen assemblies connected to corresponding circulation port assemblies. Each set of one of the flow port assemblies and one of the screen assemblies is configured to perform sand control with respect to a corresponding zone of the wellbore. The flow port assemblies are selectively activatable to allow selective performance of sand control with respect to the corresponding zones.
Claims25
A sand-control tool string for use in a wellbore having plural zones, comprising:
- plural flow port assemblies;
- and
- plural screen assemblies connected to corresponding flow port assemblies, wherein each set of one of the flow port assemblies and one of the screen assemblies is configured to perform sand control with respect to a corresponding zone of the wellbore, wherein the flow port assemblies are selectively activatable riglessly to allow selective performance of sand control with respect to the corresponding zones.
A method of performing sand-control in a wellbore, comprising:
- lowering a sand-control tool string into the wellbore that has plural zones, where the sand-control tool string has multiple pairs of circulation port assembles and screen assemblies;
- and
- selectively activating the circulation port assemblies riglessly to perform selective sand control with respect to the corresponding zones.
A system comprising:
- a tubing string;
- and
- a sand-control tool string attached to the tubing string for deployment into a wellbore having plural zones, the sand-control tool string comprising:
- plural flow port assemblies;
- and
- plural screen assemblies connected to corresponding flow port assemblies, wherein each set of one of the flow port assemblies and one of the screen assemblies is configured to perform sand control with respect to a corresponding zone of the wellbore,
- wherein the flow port assemblies are selectively activatable riglessly to allow selective performance of sand control with respect to the corresponding zones.
