Upper-completion single trip system with hydraulic internal seal receptacle assembly

A spacing mechanism means for use in a tubing string, comprising:

• an overshot assembly, the overshot assembly comprising an upper sleeve, a lower sleeve, a piston, and a pin housing;
• means for connecting the upper sleeve to the pin housing;
• means for selectively connecting the piston to the upper sleeve;
• means for connecting the lower sleeve to the pin housing;
• a mandrel assembly, the a nipple and at least one stinger;
• means for connecting the nipple to the at least one stinger;
• means for selectively connects the overshot assembly to the mandrel assembly;
• and
• means for providing movement of the overshot assembly with respect to the mandrel assembly.

A method of providing a mechanism to accommodate a change in the length of a tubing string comprising:

• connecting an overshot assembly to an upper portion of a tubing string, wherein the overshot assembly includes an upper sleeve, a lower sleeve, a piston, and a pin housing;
• wherein at least one connector selector connects the piston to the upper sleeve;
• connecting a mandrel assembly to a lower portion of a tubing string, wherein the mandrel assembly includes a nipple and at least one stinger;
• connecting the mandrel assembly to the overshot assembly by a load pin located in a first position;
• removing the at least one connector, wherein the piston moves downward with respect to the upper sleeve and moves the load pin to a second position;
• releasing the connection between the mandrel assembly and the overshot assembly;
• moving the overshot assembly with respect to the mandrel assembly, wherein the movement is due to a change in the length of the overall tubing string.

A downhole alignment apparatus comprising:

• an outer sleeve having an upper end and a lower end, the lower end of the outer sleeve includes at least one tapered surface;
• an inner sleeve having an upper end and a lower end, wherein the inner sleeve includes at least one tapered surface;
• wherein the outer sleeve circumscribes the inner sleeve;
• wherein the outer sleeve and inner sleeve are biased such that a cavity initially exists between the at least one tapered surface of the inner sleeve and the at least one tapered surface of the outer sleeve;
• wherein upon the application of a force the inner sleeve may rotate with respect to the outer sleeve and the outer sleeve may move towards the inner sleeve to reduce the cavity;
• and
• wherein the tapered surface of the inner sleeve is adapted to mate with the tapered surface of the lower end of the outer sleeve when the at least one tapered surface of the inner sleeve is aligned with the at least one tapered surface of the outer sleeve.

A latch anchor system comprising:

• a crossover attached for attachment to a tubing string;
• a latch, an upper portion of the latch circumscribed by the crossover and a lower portion of the latch including collet fingers, wherein the collet fingers are adapted to engage a packer;
• a mandrel, wherein the latch is attached to the exterior of the mandrel;
• a shear ring, the shear ring circumscribing the mandrel below the latch, wherein the shear ring is adapted to drive the collet fingers radially outward due to upward movement of the mandrel;
• and
• at least one shear screw, wherein the shear screw selectively connects the shear ring to the mandrel.

A tubing string connection system comprising:

• a spacing mechanism, wherein the spacing mechanism adjusts to the expansion and contraction of the tubing string;
• an alignment apparatus, wherein the alignment apparatus may rotate independent of the tubing string to provide proper alignment with a downhole component;
• and
• a shearable anchor latch, wherein the shearable anchor latch is adapted to engage a packer and provides the selective release of a portion of the tubing string without rotation of the tubing string.
