Abstract: A packer assembly can include an annular seal element and an end ring including leaves formed on a body of the end ring, whereby the leaves are biased radially outward when the seal element extends radially outward. A method of sealing an annulus in a subterranean well can include positioning a circumferential series of leaves radially outwardly overlying an annular seal element of a packer assembly, and the leaves pivoting radially outward in response to swelling of the seal element. Another packer assembly can include an annular seal element which swells in response to contact with a selected fluid in the well, and an end ring including an end ring body with a removable portion being engaged with the end ring body via interlocking profiles.

Abstract: A mixer (1) for processing one or more fluid media (2) and optionnally one or more solid media (3). The mixer (1) consists of a tank (4) with one or more filling openings (5) and a discharge opening (6) at the bottom of the tank (4), and a mixer unit (8) provided at the bottom of the tank. The mixer unit (8) includes a rotor (9), an inlet (10) and an outlet (11). The mixer unit (8) also includes a valve arrangement (12) with a valve body (13), an inlet (14) communicating with the outlet of the mixer unit (8), a first outlet (14) communicating with the discharge opening (6) of the tank and a second outlet (15) communicating with an inlet in the tank (4). A connection (20) may be provided between the first outlet (15) of the valve arrangement and at least one of the filling openings of the tank.

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.
