MULTI-STAGE WELL SYSTEM AND TECHNIQUE |
| 摘要 |
A technique that is usable with a well includes communicating an untethered object in a passageway downhole in the well and using a cross-sectional dimension of the object and an axial dimension of the object to select a seat assembly of a plurality of seat assemblies to catch the object to form an obstruction in the well. |

1. A system usable with a well, comprising:
a string comprising a passageway; plurality of assemblies disposed on the string such that the passageway extends through the assemblies, the plurality of assemblies comprising a first assembly and a second assembly; and an untethered object adapted to be communicated through the passageway and be sufficiently radially compressed in response to engaging the first assembly to cause the object to pass through the first assembly and having a dimension to cause the object to be engaged by the second assembly to sufficiently restrict radial compression of the object to cause the object to be retained by the second assembly. |
