A completion system for arrangement in a borehole including a lower completion, an upper completion string, and an intermediate assembly engaged between the lower completion and the upper completion string. The intermediate assembly includes a single barrier valve only. The barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitions to a closed position via the upper completion string when the upper completion string is pulled out of the borehole.

1. A completion system for arrangement in a borehole comprising: a lower completion having an opening therein;an upper completion string; andan intermediate assembly engaged between the lower completion and the upper completion string, the intermediate assembly including a barrier valve configured to occlude flow from the opening in the lower completion when the barrier valve is closed and the intermediate assembly is engaged with the lower completion, the barrier valve operatively arranged to be maintained in an open position when engaged with the upper completion string and configured to transition to a closed position in response to the upper completion string being withdrawn from the intermediate assembly. 2. The system of claim 1, wherein the intermediate assembly includes a packer. 3. The system of claim 2, wherein the upper completion string includes a shifting tool that extends through the packer device for engagement with the barrier valve. 4. The system of claim 1, further comprising a subsequent intermediate assembly stacked with the intermediate assembly, the subsequent intermediate assembly having a subsequent barrier valve. 5. The system of claim 4, wherein the intermediate assembly is engaged between the subsequent intermediate assembly and the lower completion and the subsequent intermediate assembly is engaged between the intermediate assembly and the upper completion string. 6. The system of claim 5, wherein the upper completion string includes a first shifting tool operatively arranged for enabling the subsequent barrier valve to transition between open and closed positions and the subsequent intermediate assembly is arranged with a second shifting tool for holding the barrier valve in an open position while the subsequent intermediate assembly is engaged with the first intermediate assembly. 7. The system of claim 1, wherein the barrier valve includes an axially slidable sleeve manipulated by the upper completion string. 8. The system of claim 7, wherein the sleeve includes a first set of at least one port that is selectively alignable with a second set of at least one port in a housing of the barrier valve. 9. The system of claim 1, wherein the lower completion includes at least one assembly for enabling stimulation, hydraulic fracturing, frac packing, gravel packing, or a combination including at least one of the foregoing. 10. The system of claim 1, wherein the upper completion string is a production string. 11. The system of claim 10, wherein the production string comprises an artificial lift system. 12. The system of claim 1, wherein the intermediate assembly includes a shroud enclosing a housing of the barrier valve. 13. A method of completing a borehole comprising: engaging an intermediate assembly with an opening in a lower completion, the intermediate assembly having a barrier valve;occluding flow from the opening with the intermediate assembly if the barrier valve is closed while the intermediate assembly is engaged with the opening in the lower completion; andengaging the intermediate assembly releasably with an upper completion string, the barrier valve being configured to transition to an open position upon engagement with the upper completion string and transition to a closed position upon withdrawal of the upper completion string from the intermediate assembly. 14. The method of claim 13, further comprising running the intermediate assembly in on the upper completion string. 15. The method of claim 14, wherein the upper completion string is a production string. 16. The method of claim 14, wherein the upper completion string includes a removable plug for enabling a packer device of the intermediate assembly to be set by pressurizing fluid against the removable plug. 17. The method of claim 13, further comprising pulling out the upper completion string before engaging the intermediate assembly with a subsequent upper completion string. 18. The method of claim 13, wherein the upper completion string and the subsequent upper completion strings are both production strings. 19. The method of claim 13, wherein the upper completion string is a work string and the subsequent upper completion string is a production string. 20. The method of claim 13, wherein the intermediate assembly includes a packer device. 21. The method of claim 13, further comprising transitioning the barrier valve between the open position and the closed position via a slidable sleeve. 22. The method of claim 13, further comprising engaging a subsequent intermediate assembly having a subsequent barrier valve with the intermediate assembly after pulling out the upper completion string, wherein the subsequent intermediate assembly is operatively arranged for holding the barrier valve of the intermediate assembly in its open position when engaged therewith. 23. The method of claim 22, further comprising running in a subsequent upper completion string, the subsequent upper completion string engaging with the subsequent intermediate assembly for enabling transition of the subsequent barrier valve between open and closed positions thereof. 24. The method of claim 13, wherein a plurality of subsequent intermediate assemblies are stacked upon each other, with the upper completion string or any subsequently run upper completion strings engaging an uppermost of the plurality of subsequent intermediate assemblies.
