Abstract: Magnetic means for managing and stopping leaks in metal pipes such as we 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 int a pipe riser. The magnetic collar creates a seal with the pipe riser, which may the be welded in place, if desired. Additionally, a magnet may be positioned proximat a leak in a side wall of a pipe riser to seal the leak. The magnet may be shaped t conform to the shape of the pipe riser, and a seal gasket provided around an edg 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 pip riser so that killing fluids may be pumped into the well bore, if desired.

Abstract: An offshore universal riser system. A riser system includes a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device releasably secures the valve module in the flow passage. A method of constructing a riser system includes the steps of installing the valve module in the flow passage, and installing at least one annular seal module in the flow passage. The annular seal module is operative to prevent fluid flow through an annular space between the riser string and a tubular string positioned in the flow passage. Drilling methods include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, is dimensioned for installation through a rotary table.

Abstract: A seal assembly disposed within a radial seal groove to sealingly engage a bonnet within a bore. The seal assembly includes a radial seal surface, an axial seal surface, a vent surface, and an axial preload surface. The seal assembly is thrust towards a longitudinal wall and away from a radial wall of the radial seal groove when pressure in a high-pressure zone increases.
