Problems solved by technology

However, the use of aluminum bypass plugs requires the introduction of acid into the pores, and the aluminum plugs may dissolve at an unpredictable rate depending on the amount and chemical composition of both acid and aluminum plugs
Additionally, the tubing valve may block acid flow to the aluminum plug

Embodiment Construction

[0035] Certain aspects and embodiments of the present invention relate to components that can be placed in a borehole (such as a wellbore) of a formation for producing hydrocarbon fluids from the formation. The assembly according to some embodiments of the present invention may include a fluid restricting member disposed in a groove between the inner wall of the center tube and the outer wall of the assembly housing. The fluid restriction member can be configured to at least partially prevent fluid flow for a certain period of time. At least a portion of the fluid restricting member can be removed from the groove after being exposed to the environment of the channel to form a bypass that allows fluid flow and equalizes pressure. The bypass can be a bypass of the tubing valve. In some embodiments, the fluid confinement member may degrade at a known or predicted rate when exposed to the environment of the channel, and after at least partial degradation, it may be removed from th...

Abstract

Assemblies that can be disposed in a subterranean bore are described. An assembly can include a fluid restricting member in a groove. At least a portion of the fluid restricting member can be removable from the groove after being exposed to an environment of the bore to form a bypass to a tubing valve. The fluid restricting member may be positioned in a groove located between an inner wall of a base pipe and an outer wall of an assembly housing that is exterior to the base pipe. The fluid restricting member can cooperate with at least part of the tubing valve to block fluid flow and pressure equalization before at least a portion of the fluid restricting member is removed from the grove.

Description

Technical field [0001] The present invention relates generally to components for subsurface fluid production, and more specifically (though not necessarily only to) an assembly that includes a fluid restricting member configured to after the assembly is positioned in a wellbore The fluid restricting member can be removed from the groove. Background technique [0002] Hydrocarbons can be produced through wellbores that pass through the formation. Various components can be arranged in the bore to produce hydrocarbons. For example, perforated pipes can be used to receive hydrocarbons, inflow control devices can be used to control the flow of hydrocarbons from the formation to the perforated pipes, and filter assemblies can be used to provide stability to the formation in the production zone and prevent hydrocarbons from entering the perforation. The pipeline filters particulate matter from hydrocarbons before. [0003] Pressure can be used to place certain components in the channel...
