Hydraulic locking means is provided in a dual stinger latching mechanism which hydraulic locking means secures tubular conduit within the packer latching mechanism against pressure below the packer tending to pump the conduit out. The hydraulic locking means utilizes the pressure below the packer to activate a gripping means on the conduit which is subject to the upward pressure force.

Hydraulic holddown for well packer stinger

A unitary tubular cylindrical gripping member for well packers is disclosed having variable angled gripping teeth formed thereon and arranged to provide constant gripability of the member in well casings having different internal diameters.

Gripping member for well packer

A versatile multistring mechanically actuated well packer featuring compression or tension set utilizes unitary tubular anchor means and compressible elastomeric packer elements, with a tension-shearable emergency release.

Multiple string well packer

Apparatus for sensing the flow from a pumped well and for generating signals indicative of that flow includes an orifice flow sensing system adapted to be placed into the flowline of a pumped well and being operably connected to an electro-mechanical signal switch.
