摘要： A method for removing a downhole tool from a well bore comprises consuming at least a portion of the downhole tool within the well bore via exposure of the tool to heat and a source of oxygen. Another method of removing a downhole tool from a well bore comprises exposing the downhole tool to heat and a source of oxygen in situ within the well bore to desirably consume at least a portion of the tool within the well bore.

摘要： A wellhead isolation tool comprises a threaded drive rod coaxially aligned with a tubular mandrel having a smooth outer surface. A motor displaces the threaded drive rod vertically without rotating the drive rod to move the tubular mandrel through a wellhead into a tubular element in a well. The lower end of the tubular mandrel will sealingly engage the tubular element in the well so that treating fluids or other substances such as, but not limited to, chemicals and erosive flows, can be displaced therethrough at high pressures into the well to fracture or otherwise treat the well without damaging the wellhead.

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 downhole tool having a body or structural component comprises a material that is at least partially consumed when exposed to heat and a source of oxygen. The material may comprise a metal, such as magnesium, which is converted to magnesium oxide when exposed to heat and a source of oxygen. The downhole tool may further comprise a torch with a fuel load that produces the heat and source of oxygen when burned. The fuel load may comprise a flammable, non-explosive solid, such as thermite.

摘要： A downhole tool for use in a well bore comprises an onboard navigation system for determining the location of the tool within the well bore, wherein the tool is moved along at least a partial length of the well bore via an external force. A method of locating a downhole tool in a well bore comprises deploying the tool along at least a partial length of the well bore via an external force, and self-determining the location of the tool without receiving communications from the surface. In an embodiment, the tool is a well bore zonal isolation device.

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.
