摘要： A high temperature, high pressure retrievable packer adapted for service under extreme operating conditions when the packer apparatus is held in the wellbore with a mechanical slip and a barrel slip. The barrel slip has a barrel slip body with a plurality of openings defined in the outer surface of the body. Cylindrical inserts are received in the openings. The cylindrical inserts define upward facing and downward facing gripping edges that will engage casing when the barrel slip body is radially expanded. The inserts are preferably tungsten carbide inserts. A sufficient number of inserts are included along the length and around the circumference of the barrel slip so that the barrel slip can get a good grip in the casing wall. Separate metals may be used for the barrel slip body and the inserts so that a higher yield strength alloy steel may be utilized than is possible with other barrel slip arrangements.

摘要： A packer apparatus for sealing between a tubing string and a casing in a wellbore is disclosed. The packer apparatus includes a seal assembly disposed about a packer mandrel. Upper and lower seal wedges are disposed about the packer mandrel above and below the seal assembly and may be inserted between the seal assembly and the packer mandrel to radially expand the seal assembly into engagement with the casing. The seal assembly includes an expandable elastomeric seal element having anti-extrusion bridge elements disposed in recesses at the upper and lower ends thereof. The anti-extrusion elements form an almost complete circle and thus are arcuately shaped having first and second ends with a gap therebetween. The anti-extrusion bridge elements are preferably automatically radially retractable elements so that when the seal wedges are removed from between the seal assembly and the packer mandrel, the automatically radially retractable anti-extrusion elements will apply a radially inwardly directed force sufficient to cause the seal assembly to radially retract and close around the packer mandrel.

摘要： The present invention is directed to disposable composite downhole tool formed of a resin-coated fiber. The fiber is formed of a degradable polymer, such as a poly(lactide) or polyanhydride. The resin is formed of the same degradable polymer as the fiber. It chemically bonds to the fiber, thereby making a strong rigid structure once cured. The fiber may be formed into a fabric before being coated with the resin. Alternatively, the fiber is formed of a non-biodegradable material.

摘要： A disposable downhole tool or a component thereof comprises an effective amount of biodegradable material such that the tool or the component thereof desirably decomposes when exposed to a wellbore environment. In an embodiment, the biodegradable material comprises a degradable polymer. The biodegradable material may further comprise a hydrated organic or inorganic solid compound. The biodegradable material may also be selected to achieve a desired decomposition rate when the tool is exposed to the wellbore environment. In an embodiment, the disposable downhole tool further comprises an enclosure for storing a chemical solution that catalyzes decomposition. The tool may also comprise an activation mechanism for releasing the chemical solution from the enclosure. In various embodiments, the disposable downhole tool is a frac plug, a bridge plug, or a packer.
