Devices, systems, and methods for adding a coupling system onto the existing accessory thread on a rifle barrel, which allows for existing terminal muzzle devices (such as but not limited to muzzle brakes, flash hiders, muzzle suppressors, and the like) to remain on the barrel and not be removed when accessory devices, such as but not limited to silencers, percussion shrouds, golf ball launchers, tennis ball launchers, cartridge oil filters, and the like, are used with threaded gun barrels.

Integrated muzzle adapter coupling system

A method having the following steps: running a circulation valve comprising a reactive material into the well bore on the casing; reverse-circulating an activator material in the well bore until the activator material contacts the reactive material of the circulation valve; reconfiguring the circulation valve by contact of the activator material with the reactive material; and reverse-circulating a cement composition in the well bore until the reconfigured circulation valve decreases flow of the cement composition. A circulation valve for cementing casing in a well bore, the valve having: a valve housing connected to the casing and comprising a reactive material; a plurality of holes in the housing, wherein the plurality of holes allow fluid communication between an inner diameter of the housing and an exterior of the housing, wherein the reactive material is expandable to close the plurality of holes.

Casing shoes and methods of reverse-circulation cementing of casing

Improved casing strings, and methods of using improved casing strings in subterranean cementing operations, are provided. An example of an apparatus is a pipe string comprising at least one pipe section and a delivery system of an activator. Another example of an apparatus is a pipe string comprising at least one pipe section and a delivery system of a set retarder. An example of a method is a method of cementing in a subterranean formation. Other examples of methods are methods of cementing in a subterranean formation comprising a well bore.

Methods of using casing strings in subterranean cementing operations

Methods and systems for reverse-circulation cementing in subterranean formations are provided. An example of a method is a method of cementing casing in a subterranean well bore, comprising inserting a casing into the well bore, the casing comprising a casing shoe; equipping the casing with a well head, and a casing inner diameter pressure indicator; flowing an equilibrium fluid into the well bore; flowing a cement composition into the well bore after the equilibrium fluid; determining from the well-bore pressure indicator when the well bore pressure has reached a desired value; discontinuing the flow of cement composition into the well bore upon determining that the well bore pressure has reached a desired value; and permitting the cement composition to set in the subterranean formation. Examples of systems include systems for cementing casing in a well bore.

Methods for reverse-circulation cementing in subterranean formations

A method for sealing an annulus defined between an outer casing and an inner casing, the method having steps as follows: fastening a lock ring to an anchor base, wherein the lock ring comprises a threaded fastener of the lock ring to the head; positioning the lock ring and anchor base about the outer casing; fastening a limit clamp to an exterior surface of the outer casing; repositioning the lock ring and anchor base so that the anchor base is in contact with the limit clamp; fastening a head to the lock ring; providing an opening for fluid communication with the annulus through the head; positioning a plug about the inner casing and in contact with the inner casing and the head; positioning a seal fitting clamp about the inner casing and in contact with the plug; positioning a bull cap about the inner casing and in contact with the seal fitting clamp; and fastening the bull cap to the head.

Methods and systems for reverse-circulation cementing in subterranean formations

Methods and systems for cementing casing in well bores drilled in subterranean formations, and more particularly, methods and systems for cementing casing in a well bore without surface casing or a well head are provided. A method provided herein may comprise sealing an annulus at the mouth of the well bore with a seal; pumping a cement composition into the annulus through the seal; and taking circulation fluid returns from the inner diameter of the casing. A system provided herein may comprise a seal of an annulus at the mouth of the well bore; a cement composition pump fluidly connected to the annulus through the seal; and a coupling connected to the exposed end of the casing for taking circulation fluid returns from the inner diameter of the casing.
