Abstract: A connection apparatus. The apparatus comprises a wing mandrel having a first check valve disposed within an inner bore of the wing mandrel, a thread mandrel abutting the wing mandrel, with the thread mandrel having outer threads and a second check valve disposed within an inner bore of the thread mandrel. The apparatus further comprises a latch dog carrier disposed about the wing mandrel and the thread mandrel, with the latch dog carrier having a plurality of dogs, wherein the dogs having an inner portion with threads and an outer portion with outer ribs. The apparatus further contains a shell partially disposed about the latch dog carrier, with the shell having inner ribs, and wherein the inner ribs of the shell engage the outer ribs of the dogs. The apparatus further comprises a hydraulic port configured to deliver hydraulic fluid to the latch dog carrier so that the shell moves relative to the latch dog carrier in order to disconnect. A method of releasing a union is also disclosed.

Abstract: A disconnect apparatus and method for use in a well bore. The apparatus comprises a top sub having a collet, and wherein the top sub has an external seal surface. The apparatus further comprises a bottom sub having a bore, and wherein the external seal surface and the bore cooperate. The apparatus further includes a support piston disposed within the collet, wherein the support piston has a plurality of fins formed on an outer portion of the support piston, and shear device, operatively attached to the top sub and the support piston, for attaching and detaching the top sub from the support piston. In one preferred embodiment, the collet member comprises a plurality of fingers having a gap between each individual finger. Also, the plurality of fingers may have an external thread formed thereon that engage an internal thread formed on the bottom sub.

Abstract: An apparatus and method for retrieving metal objects. The apparatus includes a housing with an inner part, with the housing having a first wall. The apparatus further includes a sleeve disposed within the housing, with the sleeve being constructed of a non-magnetic conduction material. A magnet is disposed within the sleeve, with the magnet having a north pole and a south pole. The apparatus further includes a container disposed within the sleeve, the container having a second wall. In the most preferred embodiment, the first wall defines a first pathway for magnetic lines of flux for the north pole of the magnet and wherein the second wall defines a second pathway for magnetic lines of flux for the south pole of the magnet so that a toroidal magnetic field is formed about the distal end of the sleeve.
