摘要： A method of removing a downhole assembly comprises contacting, in the presence of an electrolyte, a first article comprising a first material and acting as an anode, and a second article comprising a second material having a lower reactivity than the first material and acting as a cathode, the downhole assembly comprising the first article in electrical contact with the second article, wherein at least a portion of the first article is corroded in the electrolyte.

摘要： Methods of forming a cutting element include immersing at least a portion of a volume of polycrystalline diamond in a liquid electrolytic solution, applying a voltage between the polycrystalline diamond and a cathode in contact with the liquid electrolytic solution, and removing at least a portion of metal catalyst from interstitial spaces between adjacent diamond grains. The polycrystalline diamond includes interbonded diamond grains and metal catalyst particles in the interstitial spaces between adjacent grains of polycrystalline diamond material. Some methods include forming a barrier over a portion of a volume of polycrystalline diamond and transferring at least a portion of the metal catalyst from a portion of the polycrystalline diamond not covered by the barrier to a liquid electrolyte. Some methods include encapsulating a volume of polycrystalline diamond in a barrier and selectively removing a portion of the barrier from a first portion of the volume of polycrystalline diamond.

摘要： Actuation and control of the deployment of a polymeric memory-shape material on a wellbore device on a downhole tool may be accomplished by treating a compacted or compressed polymeric memory-shape material with a deployment fluid to lower its Tg and/or decrease its rigidity, thereby softening the polymeric shape-memory material at a given temperature and triggering its expansion or recovery at a lower temperature. Alternatively, the deployment of the compacted or compressed polymeric memory-shape material may be prevented or inhibited by shielding the material with an environment of a fluid that does not substantially lower its Tg, decrease its rigidity or both, and then subsequently contacting the material with a deployment fluid.

摘要： A method of forming polycrystalline diamond includes forming metal nanoparticles having a carbon coating from an organometallic material; combining a diamond material with the metal nanoparticles having the carbon coating; and processing the diamond material and the metal nanoparticles having the carbon coating to form the polycrystalline diamond. Processing includes catalyzing formation of the polycrystalline diamond by the metal nanoparticles; and forming interparticle bonds that bridge the diamond material by carbon from the carbon coating.

摘要： An apparatus for performing a downhole operation includes a carrier configured to be disposed in a borehole in an earth formation, and a deformable component configured to be disposed in the borehole. The deformable component includes an elastomeric material and a barrier coating disposed on a surface of the elastomeric material. The barrier coating has properties configured to resist permeation of downhole gases into the elastomeric material at downhole temperatures.

摘要： A composite particle comprises a core, a shielding layer deposited on the core, and further comprising an interlayer region formed at an interface of the shielding layer and the core, the interlayer region having a reactivity less than that of the core, and the shielding layer having a reactivity less than that of the interlayer region, a metallic layer not identical to the shielding layer and deposited on the shielding layer, the metallic layer having a reactivity less than that of the core, and optionally, an adhesion metal layer deposited on the metallic layer.
