| 141 | GRAVEL PACK INNER STRING HYDRAULIC LOCATING DEVICE | EP13702272.9 | 2013-01-04 | EP2800868B1 | 2018-08-22 | BROUSSARD, John, P.; VAN PETEGEM, Ronald; HALL, Christopher; ZIMMERMAN, Patrick, J.; RITCHEY, Brian; VAN CLIEF, Rockni |
| A downhole assembly, such as a toe-to-heel gravel pack assembly, has a body with a body passage, outlet ports for slurry, and screens for fluid returns. An inner string deploys in the body to perform the toe-to-heel gravel packing. A telescoping adjustment device allows the inner string to space out properly when deployed to the toe of the assembly. Sealing surfaces of a locating device in the body separate a sealable space and seal against seals on the inner string movably disposed therein. Fluid pumped in the string produces a pressure buildup when the string's port communicates with the sealable space. The pressure buildup indicates that the tool is positioned at a first location in the assembly, and other positions for placement of the tool can then be calculated therefrom. | ||||||

| A screening assembly with a swellable packer incorporated onto the exterior of the screen that swells in the presence of water or hydrocarbons. The swellable packer swells at a rate that allows the gravel pack operation to proceed without hindering the gravel pack operation but then swells to seal the annular region around the exterior of a blank tubular at the upper end of the screen. By running in a swellable packer with the screen assembly at least one additional trip into the wellbore may be eliminated. | ||||||

The invention provides a method and apparatus for use in a wellbore gravel pack operation. The method comprises providing an apparatus in a downhole annulus. The apparatus comprises a mandrel and a swellable element (208)formed from a material selected to increase in volume when exposed to a downhole stimulus. The method comprises placing a gravel pack (206A) below the apparatus via the downhole annulus in which the apparatus is located, and placing a gravel pack (206B) above the apparatus. Subsequent to placing the gravel packs, the swellable element (208) is increased in volume to create an annular barrier in the wellbore. The invention allows isolation of multiple intervals of a well in a single gravel pack operation using swellable elastomers, and does not rely on the use of shunt tube alternate path systems.
