  • Patent number: 9476277
    Abstract: Magnetic means for managing and stopping leaks in metal pipes such as well bores and pipe risers is provided. A magnetic leak arrestor comprises a spool with magnetic collar disposed thereabout. The spool has a tapered end for inserting into a pipe riser. The magnetic collar creates a seal with the pipe riser, which may be welded in place, if desired. Additionally, a magnet may be positioned proximate a leak in a side wall of a pipe riser to seal the leak. The magnet may be shaped to conform to the shape of the pipe riser, and a seal gasket provided around an edge portion of the magnet. A slurry of magnetically active material may be provide inside the pipe to seal the leak in the side wall or to provide a blockage in the pipe riser so that killing fluids may be pumped into the well bore, if desired.

  • Publication number: 20100144561
    Abstract: A water-base fluid for use in drilling, cementing, workover, fracturing and abandonment of subterranean wells through a formation containing a shale which swells in the presence of water. In one illustrative embodiment, the drilling fluid includes, an aqueous based continuous phase, a weighting agent, and a shale hydration inhibition agent. The shale hydration inhibition agent should have the general formula (I) in which R is independently selected from alkyls and hydroxyl alkyls comprising 1 to 15 carbon atoms, and X is an anion. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the drilling fluid. The drilling fluid may be formulated to include a wide variety of components of aqueous based drilling fluids, such as weighting agents, fluid loss control agents, suspending agents, viscosifying agents, rheology control agents, as well as other compounds and materials known to one of skill in the art.

  • Patent number: 7618925
    Abstract: A method of using a water-base wellbore fluid in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the reaction product of a hydrogenation reaction of the product of the reaction of an aromatic amine with an aldehyde, preferably formaldehyde. Alternatively the shale hydration inhibition agent may be the reaction product of a hydrogenation reaction of the product of the reaction of aniline and formaldehyde. In one illustrative embodiment, the shale hydration inhibition agent is selected from the class of compounds known as polycycloaliphatic amines. Further the shale hydration inhibition agent may be present in the form of a free-base or in the form of an acid salt of the disclosed amine compounds.
