ABSTRACT:
A thru-tubing gravel packing operation utilizing inflatable packing elements and a flow cross-over assembly which selectively opens flow ports for effecting steps in the gravel packing operation and which further provides concentric flow paths through the cross-over assembly for transmitting fluid pressure to valving means and the interior of the packing element or elements to move them to set and sealed condition, whereby the outer diameter of the inflatable element in the sealed condition may preferably expand to at least twice the outer diameter of such element in the initial or run-in condition, for the sequential setting thereof while also transmitting a variation in the pressured fluid to actuate a valve for circulation of the gravel packing fluid exterior of the assembly and for permitting return of fluids through the assembly without the gravel. When plural packing elements are incorporated, the device includes valving components which permit the setting of the lower or sump packer prior to the setting of the gravel pack packer as well as the opening of the gravel packing sleeve valve and a valving component within the gravel packing screen for circulation. The device is mechanically manipulatable after the setting operation for various steps in gravel packing of a subterranean well through tubing introduced through production tubing disposed through a Christmas tree.
