International Classification:

E21B 17/046

US Classification:

166378, 1662426

Abstract:

An apparatus for aligning a component includes: a downhole sub including a plurality of first axially extending tapered members, the plurality of first axially extending tapered members configured to engage a plurality of second axially extending tapered members of a downhole carrier in an interlocking engagement and prevent rotation of the downhole carrier relative to the downhole sub.

Abstract:

A pressure test system for use in downhole fluid injection includes a shear plug assembly disposed along a flow path defined in a sump housing. The sump housing also includes a sump cavity positioned downstream of the shear plug assembly. A shear element of the shear plug assembly secures the shear plug assembly in a first position within the flow path, so that the shear plug assembly blocks fluid flow through the sump housing. Following a pressure test, fluid pressure on the shear plug assembly may be increased until the shear element of the shear plug assembly shears, after which, the pressurized fluid drives the shear plug assembly into the sump cavity, permitting flow to bypass the sump cavity through bypass channels. The bypass channels and other flow paths may be arranged to function as a pressure wave muffler in order to protect pressure sensitive components after shear out.
