Abstract: An apparatus for use in a wellbore is disclosed that in one non-limiting embodiment includes a set down tool that includes a locating device configured to engage with an outer member at a selected location, a set down device configured to set down in a set down profile in the outer member when the set down device is activated, an alignment device for activating the set down device and a locking device that operates the alignment device to activate the set down device while maintaining the locating device engaged with the outer member.

Abstract: An apparatus for use in a wellbore. The apparatus includes a locating device having a locating collet configured to engage with a locating profile on a housing and disengage from the locating profile when a first pull load is applied to the locating collet, a delay device that prevents application of the first pull load on the locating collet when it is engaged with the locating profile until the delay device has been activated, and a locking device configured to prevent activation of the delay device until a second pull load less than the first is applied on the locking device for a selected period of time.

Abstract: A downhole tool for preventing flow within a portion of an oil/gas well includes a mechanism for preventing premature deployment of portions of the tool. The bottom portion of the tool is configured to insure flow through the tool from a zone below the tool after certain processes have been completed within the well.

Abstract: In one aspect, a device for use in a wellbore includes a tubular body; a barrier member associated with an outer surface of the tubular body configured to retain a proppant; an actuating member associated with the barrier member configured to expand the barrier member in an annular direction; and a fluid channel associated with an upper extent and a lower extent of the barrier member, configured to allow a fluid flow therethrough.
