Abstract: The retrievable packer system includes a packer mandrel, a lock ring, an upper cone, a lower cone, a slip device, a retrieval mandrel, and a slotted retrieval sleeve. The lock ring is attached to the packer mandrel, followed by the upper cone, the slip device, the lower cone, and the retrieval mandrel. The upper connection sleeve and the lower connection sleeve cover the packer mandrel so as to form a chamber in fluid connection with slip flow channels of the slip device. The packer system is run into the borehole with the slotted retrieval sleeve in the first position relative to the lower cone and the slip device in the run-in position. The packer system is set and can be locked at a location in the borehole. The slotted retrieval sleeve can push the upper cone to return the slip device to the run-in position for retrieval of the packer system.

Abstract: An expandable anchor/seal is pushed up a ramp until making contact with the surrounding tubular as or after the anchor/seal contacts the same tubular. The setting sleeve is made from high yield steel that has a weakened leading end to reduce the force required to push the leading end and the anchor/seal and an outer surface treatment at a leading end that engages or penetrates the wall of the surrounding tubular. Preferably a plurality of fingers are formed with axially oriented slots starting from a leading end allowing fingers to flex as they ride up the ramp on the mandrel for setting the anchor/seal and locking that set with the setting sleeve exterior surface configuration that can abut or penetrate the surrounding tubular.

Abstract: The present invention generally relates to an anchor seal for an expandable tubular assembly. In one aspect, an anchoring seal assembly for creating a seal portion and an anchor portion between a first tubular that is disposed within a second tubular is provided. The anchoring seal assembly includes an expandable annular member attached to the first tubular. The annular member has an outer surface and an inner surface. The anchoring seal assembly further includes a seal member disposed in a groove formed in the outer surface of the expandable annular member. The seal member has one or more anti-extrusion spring bands embedded within the seal member, wherein the outer surface of the expandable annular member adjacent the groove includes a rough surface. The anchoring seal assembly also includes an expander sleeve that is configured to radially expand the expandable annular member to create the seal portion and the anchor portion.

Abstract: Downhole oil tools such as anchors and packers with mechanical setting and sealing mechanisms are not able to travel through narrower casing and then set in wider casing. This invention is a sealing mechanism which can expand enough to set a tool in a wider casing, but still travel through the narrower casing or tight spot above.

Abstract: A disintegrating plug uses a setting tool to push a swage into the plug body that has external ribs that contact the wall of the surrounding tubular. The ribs retain the body to the surrounding tubular wall with frictional contact. Some leakage may ensue but in fracturing some leakage does not matter if enough volume under the right pressure reaches the formation. The sheared member during the setting comes out with the mandrel that is part of the setting tool. In an alternative embodiment one or more o-rings are used to seal while anchoring is assisted by the hardened insert(s) that can be snap fitted in using rib flexing or that can be a c-ring that is expanded and snapped in. The o-ring(s) are axially spaced from the insert(s).
