Abstract
An inflow control device including a valve responsive to pressure inputs, and a fluid discriminator having a first structure that supports a first flow regime and a second structure that changes the flow regime to exhibit a higher pressure, a first pressure tap at the first structure and a second pressure tap at the second structure, the taps experiencing a differential pressure that is different for water and for oil flowing through the discriminator, and the first and second pressure taps connected to the valve. A borehole system, including a borehole in a subsurface formation, a string in the borehole, and an inflow control device disposed within or as a part of the string.
