    摘要: A subterranean well assembly and method of installation which uses a selectively rupturable flow control device to initially block flow and after rupture to allow flow therethrough. The selectively rupturable device is eccentric, in that, it withstands higher pressures without rupture in a flow direction which ruptures when lower pressures are applied to the device in the opposite direction. The rupturable device is installed in a subterranean well in the flow path between the production tubing string and casing.
