Abstract: An apparatus and method of conveying magnetic particles into a wellbore is disclosed. A plurality of particles which are magnetically attracted to one another in response to exposure to a magnetic field are delivered downhole via a degradable material. The degradable material confines the particles and conveys the particles to a desired location downhole. The structure comprising the degradable material and the confined particles can be lowered into a subterranean well by a cable or wire, or alternatively released into the well under the influence of gravity and flow induced forces. The material degrades in response to conditions encountered in a subterranean environment thus releasing the particles.

Abstract: A hydraulic regulating mechanism for disposal in a well. The mechanism includes a degradable metal based element and a swellable component for hydraulic regulation. The mechanism is configured for ease of setting and removal by allowing degrading of the metal based element upon exposure of certain downhole conditions to trigger shrinking of the swellable component. Further, the swellable component may be initially set by exposure to downhole conditions as well. Ultimately, a mechanism is provided which may effectively regulate high pressure applications downhole and yet, as a practical matter, be removed via a displacement or drill out that may take less than 15 to 30 minutes to achieve.

Abstract: A downhole device with compressive layer at the surface thereof. Such devices may be particularly well suited for survivability in the face of potentially long term exposure to a downhole environment. Techniques for forming protective compressive layers at the surfaces of such devices may include positioning devices within a chamber for bombardment by high frequency particles. As a manner of enhancing the compressive layer thickness and effectiveness, low temperature conditions may be applied to the device during the high frequency treatment.
