An inflatable element utilizing a solid or particulate laden fluid as an expansion media. A fluid component of the solid or particulate laden fluid is exhausted from a defined area of the element to leave substantially only particulate matter therein to maintain the expanded state of the seal. A method for sealing includes pumping a solid laden or a particulate laden fluid to an expandable, pressurized element. A fluid component of the solid or particulate laden fluid is removed from the expandable element with substantially solid material comprised to maintain the expanded element in the expanded condition.

A gravel pack screen assembly has one or more hollow flight augers that a continuous or segmented with multiple upwardly oriented gravel entrances and multiple downwardly oriented gravel exits. The gravel passes through the auger and around any bridge. The auger helps advance the screen into position as well as to centralize it during gravel deposition. The auger protects the screen during run in as well as the internal passages that pass through it due to its structural rigidity. An alternative embodiment features spirally wound tubes with staggered exit locations for better distribution of the gravel.

A well servicing assembly utilizes a plug mechanism for preventing fluid loss into a formation. The assembly includes a string of tubing which carries a packer, a perforating gun, a running tool, and a latch assembly. After perforating, the operator pulls the tubing upward, leaving the packer in place. The latch assembly engages the packer. The latch assembly has a plug contained therein which prevents downward flow of fluid through the packer as the tubing string is retrieved to the surface. After removing the perforating gun, the tubing string may be again lowered and re-engaged with the latch assembly. The latch assembly may be then repositioned below the packer.

The invention features a perforating gun, with an external auger, which can be mounted to a tubing string. The auger facilitates removal of the gun after the sand is placed in the perforations. The perforating gun with external auger promotes the clean-up of the debris from the perforations after the gun is shot and facilitates the movement of the gun out of the sand. The sand can be spotted near the perforations without exposure to the formation of any kill fluids. The perforating gun with external auger need not be moved prior to admission of sand into the perforations. The assembly can be used so that preferred fluids, such as stimulating fluids, can be used to circulate the sand until the sand has been spotted adjacent the formation, whereupon the stimulating fluid is squeezed into the formation, leaving the sand in the perforations. The amount of fluid displaced into the formation is minimized and the selection of fluid helps to stimulate the subsequent flow during production.
