Abstract: A downhole system includes a lower completion having at least one tubular including a first end and a second end terminating at a shoe. The at least one tubular defining a flow path. A packer is arranged at the first end. A fluid loss control valve (FLCV) is arranged between the packer and the shoe. A screen system is arranged between the FLCV and the shoe. The screen system includes a screen and a non-mechanically operated flow control valve that selectively isolates the flow path from formation fluids passing through the screen. A wellbore clean out string is insertable into the lower completion. The wellbore clean out string includes a selectively activated casing cleaner and a setting tool. The selectively activated casing cleaner is spaced from the setting tool.

Abstract: A system for performing a downhole operation including a tubular string having a locking profile non-movably located therewith. At least one member is movably mounted with the string and includes an engagement profile. A tool is runnable with the string and has at least one sub with a key. The key is selectively engagable and disengagable with the engagement profile for enabling the tool to control movement of the member with respect to the string when engaged therewith. The key is engagable with the locking profile for restricting relative movement between the string and the tool when engaged therewith. A method of performing a downhole operation is also included.

Abstract: A gravel packing system includes at least two packers with at least one of the two packers being sealable to an open hole, a barrier sealably engaged with the at least two packers defining an annular space between the open hole and the barrier, a cross-over tool operably connectable to at least one of the at least two packers and the barrier, and at least one regulator in operable communication with the barrier configured to maintain a substantially constant pressure in the annular space while gravel is packed at a location downstream of at least one of the at least two packers, downstream being defined by a direction of travel of gravel being packed.
