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 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 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 rotationally operated back pressure valve includes a flapper valve with a sliding stinger tube located thereabove in a housing. An operating mandrel has a lower end portion received in a bore of the housing and the operating mandrel extends upward out of the upper end of the housing. The operating mandrel may be connected to a work string for rotation by the work string. A threaded engagement is provided between the operating mandrel and the stinger tube so that the stinger tube can be selectively moved between a first and second position thereof relative to the housing in response to selected right-hand or left-hand rotation of the operating mandrel relative to the housing. In the first position of the stinger tube it is located above the flapper valve so that the flapper valve closes the housing bore. In the second position of the stinger tube it extends downward through the housing bore past the flapper valve to hold the flapper valve fully open. The tool includes locking lugs which lock the operating mandrel against rotation relative to the housing if tension is applied across the tool. This allows other tools located in the work string below the back pressure valve to be actuated by work string manipulation. When a compressional load is applied across the valve, the locking lugs disengage so as to allow rotational operation of the back pressure valve.

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.
