Abstract: An improved method and apparatus for removing metal cuttings from an oil well drilling mud stream provides a magnetic body or “ditch magnet” having end plates that extend radially and circumferentially from the magnetic body, the plates being positioned at end portions of the magnetic body. A third plate in the form of a wiper is used to dislodge metal cuttings and other metallic material from the magnetic body after the magnetic body has accumulated such metallic parts. One of the end plates can be removable to facilitate a complete scraping or wiping of the metallic parts from the metallic body by the wiper plate.

Abstract: A method and apparatus for removing metallic material from a circulating well fluid stream provides a treatment vessel that is divided into first and second sections. Each of the sections includes a magnetic field that can be in the form of one or more magnets. In one embodiment, multiple magnets are provided in each of the sections. Manifolds attach to an influent and to an effluent of the treatment vessel. Each manifold enables selective transfer of fluid to either of the selected sections. Similarly, discharge of circulating fluid can be from either of the sections via a discharge manifold. The treatment vessel enables continuous treatment by valving fluid flow so that only one section need be used at a time in order that the other section could be serviced for removing collected metallic material from the magnetic field or from the magnets.

Abstract: Method, apparatus and system for controllably conveying magnetic particles between closed chambers. Magnetic particles are magnetically attracted from a first solution-containing chamber into a motive cavity, such as may be formed in a rotor of a pump. The magnetic particle-containing motive cavity is then moved out of fluid communication with the first solution-filled chamber and moved into fluid communication with a second solution-filled chamber. Finally, the magnetic particles are magnetically releasing from the motive cavity into the second solution-containing chamber. The first and second chambers are preferably never in direct fluid communication. Because the rotor is sealed with the pump body and there is no direct fluid communication between the first and second chamber, contact between the first solution and the second solution is limited by the size of the motive cavity. Optionally, the particles are magnetically attracted by temporarily inserting a magnet into a rotor. This method has significant advantages over existing magnetic particle manipulation systems because it can be utilized as a closed system with a very innovative and low-cost approach.
