A downhole tool and method of operation thereof is provided. The downhole tool may be configured to permit fluid communication between a combined flowbore of the casing string and the downhole tool and the subterranean formation or wellbore, or both, after a pressure test has been completed, a second threshold pressure is reached or applied, and a third threshold pressure has been applied to the downhole tool.

Downhole completion tool

A downhole tool and method for performing to provide a flow path from an inner bore thereof to a wellbore annulus, wherein the flow path is provided upon the application of pressure.

Downhole tool

Selective and non-selective lock mandrel assemblies include a lock mandrel affixing to a running tool. A collet on the tool holds an inner mandrel in a downhole position in the lock mandrel. For the non-selective assembly, a biased key on the lock mandrel extends into a nipple profile, and shoulders on the key and profile stop further run-in. Operators shear a first shear pin on the running tool by jarring down, and the collet moves and releases its hold on the inner mandrel. Freed, the inner mandrel biased by a spring moves to an uphole position, and a flange fits behind the extended key to lock it in the profile. For the selective assembly, the biased key is held retracted until activated using locator dogs on the running tool to engage a transition when running uphole. Once the lock mandrel is set, operators detach the running tool from it.

One or more embodiments of a selectively openable and closable downhole tool. The wherein, the downhole tool can include an outer tubular member having an annulus port formed therethrough. The downhole tool can also include an inner tubular member. The inner tubular member can include an inner port. The inner port and annulus port can be selectively aligned to form a flow path therethrough by moving the inner tubular member relative to the outer tubular member. The downhole tool can also include a logic drum configured to selectively move the inner tubular member. The downhole tool can also include a piston assembly configured to move the logic drum.
