Abstract
A swellable packer with variable quantity feed-throughs for lines. A packer assembly for use in a subterranean well includes a generally tubular swellable seal element having an outer generally cylindrical surface, one or more cavities extending longitudinally through the seal element, and one or more longitudinally extending splits in the seal element between the outer surface and each of the cavities. One or more elongated plugs are positioned within at least one of the cavities. A method of sealing a fluid passage in a subterranean well includes the steps of: inserting one or more elongated plugs in one or more cavities which extend longitudinally through a swellable seal element of a packer assembly; and installing the packer assembly in the well. The installing step includes removing a selected number of the plugs from the cavities, and replacing the selected number of the plugs with a corresponding number of lines.
