Problems solved by technology

However, such systems suffer from a number of limitations.
As an example, the perforations may not be round or may have burrs, which may make it challenging to seal the perforations subsequent to stimulating a given region of the subterranean formation.
This may make it challenging to completely seal the perforations and / or may change fluid flow characteristics therethrough.
These challenges may occur early in the life of the hydrocarbon well, such as during and / or after completion thereof, and / or later in the life of the hydrocarbon well, such as after production of the reservoir fluid with the hydrocarbon well and / or during and / or after restimulation of the hydrocarbon well.

Abstract

Wellbore tubulars including selective stimulation ports (SSPs) sealed with sealing devices and methods of operating the same are disclosed herein. The wellbore tubulars include a tubular body that defines a tubular conduit and a plurality of selective stimulation ports. Each selective stimulation port includes an SSP conduit and a sealing device seat. The wellbore tubulars further include a plurality of sealing devices. Each sealing device includes a primary sealing portion that is seated on a corresponding sealing device seat and forms a primary seal with the corresponding sealing device seat. Each sealing device also includes a secondary sealing portion that extends from the primary sealing portion and forms a secondary seal between the primary sealing portion and the corresponding sealing device seat. The methods include methods of stimulating a subterranean formation utilizing the wellbore tubulars.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 62 / 422,356 filed Nov. 15, 2016, entitled “Wellbore Tubulars Including Selective Stimulation Ports Sealed with Sealing Devices and Methods of Operating the Same,” the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE DISCLOSURE[0002]The present disclosure relates generally to wellbore tubulars including selective stimulation ports sealed with sealing devices and methods of operating the same, and more particularly to wellbore tubulars and methods utilizing sealing devices with both primary and secondary sealing portions.BACKGROUND OF THE DISCLOSURE[0003]Hydrocarbon wells generally include a wellbore that extends from a surface region and / or that extends within a subterranean formation that includes a reservoir fluid, such as liquid and / or gaseous hydrocarbons. Often, it may be desirable to stimulate the subterranean formation, suc...
