Patent ID: 8739880

Claim:
A fluid discrimination system for use with a subterranean well, the system comprising: a fluid discriminator through which a fluid composition flows in the subterranean well; and the fluid discriminator selects through which of multiple outlet flow paths the fluid composition flows, the selection being based on at least one direction of flow of the fluid composition through the fluid discriminator, and the direction being dependent on a ratio of desired to undesired fluid in the fluid composition, wherein the at least one direction comprises first and second directions, wherein the fluid discriminator selects a first outlet flow path in response to flow of the fluid composition more in the first direction, wherein the fluid discriminator selects a second outlet flow path in response to flow of the fluid composition more in the second direction, and wherein rotational flow of the fluid composition in the first direction impinges on a structure, whereby the structure displaces and the first outlet flow path is selected.
