Abstract: An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel. Upon expansion, a sealing element engages an outer tubular and the gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release. The release tool can be combined with packers or anchors that have a thin walled feature in the mandrel, to release by pulling the mandrel apart.

Abstract: A downhole assembly includes a downhole tool including a degradable-on-demand material including: a matrix material; and, an energetic material configured to generate energy upon activation to facilitate the degradation of the downhole tool; and, a triggering system including: an electrical circuit having an open condition and a closed condition, the electrical circuit configured to be in the closed condition after movement of an object downhole that engages directly or indirectly with the triggering system; and, an igniter within the electrical circuit, the igniter arranged to ignite the downhole tool in the closed condition of the electrical circuit. In the open condition of the electrical circuit the igniter is inactive, and in the closed condition of the electrical circuit the igniter is activated.

Abstract: A packer device includes a central packer mandrel and radially surrounding expansion mandrel that carries a suitable engagement profile for engaging the surrounding casing or other tubular member. A material chamber is defined between the expansion mandrel and the packer mandrel and is filled with a filler material. In currently preferred embodiments, the filler material comprises a pliable solid, a gel or colloid, or a liquid. A setting mechanism radially expands the expansion mandrel so that the engagement profile of the expansion mandrel is brought into engagement with the surrounding tubular.

Abstract: A method of manufacturing a valve of a tool for use downhole includes changing a flow characteristic of the valve. A load is applied to a first nozzle secured in a housing of the valve via a first release member, wherein a magnitude of the load is greater than a release threshold of the first release member, to release the first release member. The first nozzle is removed from the housing, and a second nozzle is secured in the housing via a second release member.

Abstract: A tubular includes an outer surface and an inner surface defining a passage. A plug is arranged in the tubular blocking the passage. The plug is formed from a disintegrating on demand (DOD) material. An ignition device is coupled to the plug. An excitation mechanism is selectively operatively associated with the ignition device. The excitation mechanism selectively activates the ignition device to break apart the plug.
