  • Patent number: 10294750
    Abstract: A downhole assembly comprising: a tubing string located within a wellbore; an outer housing located around a portion of the tubing string; an annulus located between the outside of the tubing string and the inside of the outer housing; at least one flow path through the annulus; an inflow control device positioned within the flow path; and a degradable rod, wherein the degradable rod fits into the flow path adjacent to the inflow control device, and wherein the degradable rod is positionable within the flow path or removable from the flow path. The downhole assembly can be used in an oil or gas operation to variably control the amount of a fluid flowing through the annulus.

  • Patent number: 9428989
    Abstract: A method of variably restricting flow in a subterranean well can include resisting flow through a flow path, and then selectively opening a pressure barrier which previously prevented flow through another flow path. The flow paths are configured for parallel flow. A flow restrictor system for use with a subterranean well can include at least two flow paths configured for parallel flow, a flow restrictor which resists flow through one flow path, and a pressure barrier which prevents flow through another flow path. The pressure barrier is selectively openable to permit flow through the second flow path.
