US Patent:

40448320, Aug 30, 1977

Filed:

Aug 27, 1976

Appl. No.:

5/718151

Inventors:

Charles A. Richard - Gretna LA
John Philip Barbee - Luling LA

Assignee:

Baker International Corporation - Orange CA

International Classification:

E21B 3312
E21B 4304

US Classification:

166278

Abstract:

A packer with a liner assembly depending from it is packed off and anchored in well casing so that a screen portion of the liner assembly straddles casing perforations within a producing formation. An outer tubing string is lowered through the well casing and engaged with the packer to isolate the formation from well fluids above the packer and to provide a passage to the surface for the formation fluids. A member having crossover fluid passages and external seals engageable with internal seal surfaces in the liner and packer is lowered through the outer tubing string into the liner and packer on an inner string. Fluid passages between the two strings, and between the two strings and the interior and exterior of the liner to control the flow of circulating, washing or acidizing fluids and for placement of gravel on the outside of the liner are selectively opened or closed by manipulation of the inner string.

International Classification:

E21B 4304

US Classification:

166278

Abstract:

A hydraulic oil and gas well downhole packer apparatus for use in a well casing below a wellhead and in combination with a coil tubing unit provides a tool body having a longitudinally extending tool bore and an upper end portion that connects to the lower free end of the coiled tubing unit during use. The tool body includes an inner elongated hollow mandrel with a hydraulic piston movably disposed upon the external surface of the mandrel. The piston is movable between an initial "running" position and a final "setting" position. An external sleeve is engaged by the piston when it moves between the running and setting positions, the external sleeve engaging slips that expand to anchor the tool body to the well casing. An annular packer member is expandable responsive to sliding movement of the external sleeve and is positioned below the slips for forming a seal between the tool body and the casing at a position near the lower end portion of the tool body.

International Classification:

E21B 3700

US Classification:

166185

Abstract:

A tool (20) for washing the perforated zone of a well casing in an oil or gas well includes a tubular mandrel (24) having a flow passage (26) with means for connecting one end of the mandrel to a drill string (160) and the second end to a flow blocking valve (162). The mandrel (24) has a plurality of apertures (42) through its sidewall. A first and second radially expandable packer (64, 132) completely encircles and is carried on the mandrel at spaced positions. An outer sleeve (100) surrounds the mandrel between the packers and defines an annular chamber (116) between the sleeve and mandrel. The sleeve has apertures (104) therethrough having a combined area less than the combined area of the apertures (42) through the mandrel. First and second annular pistons (74, 100) are carried within the annular chamber (116) having one face communicating with the annular chamber and an opposite face engaging, respectively, the first and second packers. Upon injection of fluid under pressure into the tubular mandrel and the annular chamber and through the apertures in the sleeve to the exterior of the tool, pressure generated within the annular chamber moves the pistons against the packers, radially expanding them against the casing while discharging fluid exteriorly of the tool.
