Abstract: In one aspect, a degradable apparatus is disclosed, including: an inner core with a first degradation rate in a downhole environment; an outer sheath disposed around an outer extent of the inner core with a second degradation rate less than the first degradation rate in the downhole environment. In another aspect, a method of temporarily sealing a downhole zone is disclosed, including: providing an inner core with a first degradation rate in a downhole environment; providing an outer sheath disposed around an outer extent of the inner core with a second degradation rate less than the first degradation rate in the downhole environment; sealing the downhole zone with the outer sheath; exposing the outer sheath to the downhole environment; and exposing the inner core to the downhole environment.

Abstract: A vegetation trimmer with a filament enclosure has cutting filament stored inside the filament enclosure. The free end of the cutting filament extends through a portal in the filament enclosure into the cutting plane. The filament enclosure is rotated at a high rate to allow the cutting filament to cut vegetation. Additional portals in the filament enclosure provide air circulation to the cutting filament stored inside the filament enclosure to prevent heating of the cutting filament during use.

Abstract: A packer device includes a central packer mandrel and a radially surrounding expansion mandrel. At least one slip mandrel carrying wickers surrounds the expansion mandrel and is secured in place upon the expansion mandrel by an annular retaining ring. The slip mandrel is secured to the retaining ring by screw connectors that pass through the slip mandrel and into retainer segments. The retaining ring is clamped between the slip mandrel and segments. Additionally, the packer device carries a fluid seal that is made up of a thermoplastic material with elastomeric energizing elements.

Abstract: An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel and mating undulating surfaces to help maintain grip under changing load conditions. Upon expansion, pressure on a sealing element is enhanced by nodes to increase internal pressure as it engages an outer tubular. Adjacent retaining rings limit extrusion and enhance grip. A 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.
