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： A downhole valve assembly including at least one membrane permeable to a flow of a downhole fluid, the at least one membrane defining a passage through a chamber. A quantity of particles is disposed in the chamber and the at least one membrane is impermeable to the particles. The particles are responsive to a magnetic field. At least one magnetic element is operatively arranged to produce the magnetic field for enabling the at least one magnetic element to selectively move the particles between a first position at which the particles impede the flow of the downhole fluid through the at least one membrane and a second position at which the particles do not impede the flow of the downhole fluid through the at least one membrane. A method of controlling a flow of fluid is also included.

摘要： Wiper plugs or other shapes are made from shape memory foam in a size large enough to wipe or clean a tubular of a predetermined size. The plug or other shape is then reformed to a smaller dimension above its transition temperature and allowed to cool while holding that shape. The smaller shape allows delivery through a running string that is smaller than the tubular string to be wiped. Preferably before reaching the string to be wiped, the trigger is applied to get the wiper or other shape above its transition temperature where it then reverts to the prior larger dimension for effective wiping of the string that it will next pass through. The trigger can be well fluid temperature or composition, applied heat from the tubular, generated heat within the wiper or other shape, or heat released from agents introduced into the well acting alone or in conjunction with well fluids.
摘要翻译：刮水塞或其他形状由形状记忆泡沫制成，尺寸足够大以擦拭或清洁预定尺寸的管。然后将塞子或其它形状重新形成为高于其转变温度的较小尺寸，并允许在保持该形状的同时冷却。较小的形状允许通过小于待擦拭的管状串的运行的串来传送。优选地，在到达待擦拭的绳子之前，施加触发器以将擦拭器或其它形状提升到其转变温度以上，然后将其还原到先前的较大尺寸以有效擦拭下一次穿过的串。触发器可以是良好的流体温度或组成，来自管的施加的热量，在擦拭器内产生的热量或其他形状，或从引入单独或与井流体结合作用的井中的试剂释放的热量。
