  • Publication number: 20020121120
    Abstract: A method of manufacturing micro-multi-port tubing including actuating a hydraulic press to apply a force to a billet to extrude material through a die opening. The die opening defines at least two distinct segments to produce a single, unitary, continuous micro-multi-port extrusion strand having at least two distinct segments being interconnected by a web section. The method further includes separating the single, unitary, continuous micro-multi-port strand to substantially remove and/or reshape the web section to define at least two separate and independent micro-multi-port tubing segments from a single extrusion strand.

  • Patent number: 5186256
    Abstract: The present invention resides in a three directional horizontal drilling process which is suitable for the in-situ treatment or extraction of undesirable contaminants from subsurface formations.
