Title: Surface controlled liquid removal system for  gas producing wells
Inventor: ABERCROMBIE BOLLING A
IPC: E21B43/12
Filed: 1980-06-16
Granted: 1982-10-19
Abstract: ABSTRACT OF THE DISCLOSURE           Production equipment for oil and gas wells has fea-tures that allow accumulated liquid to be removed from the well without the need for a low pressure system.  This equipment also isolates the preforations from accumulated liquid back pressure, even if there is insufficient hole depth below the perforations.  The well has a tubing string located inside the casing, with the tubing in contact with the accumulated liquid.  Both the tubing and the casing are connected to the sales line.  Periodically, both the casing and tubing are shut-in, allowing formation pressure to build up in the casing.  Then the tubing is opened to the sales line to discharge its accumulated liquid, it being driven by the higher formation pressure that has built up.  To isolate the perforations from accumulated liquid, a standpipe is mounted in the casing above the perforations by a packer.  The standpipe receives the lower end of the tubing which is closed except for a passage connecting it to the annular area between the standpipe and the casing.  Pro-duced fluid flows up the standpipe in a restricted area adjacent the tubing.  At the top of the standpipe, liquid droplets drop out and accumulate above the packer between the standpipe and the casing.

Abstract: ABSTRACT            In the determination of the refractive index profile of an optical fibre by measuring the intensity of a light beam reflected from points on an end face of a fibre, spurious signals due to reflections in the optical system used and interference effects caused by their interaction with the beam are avoided by plane polarizing the transmitted beam, and placing a .pi./2 phase shifting device adjacent the fibre end face so that the reflected beam is polarized orthogonally to the transmitted beam, whereby spurious components in the received beam can be removed by a suitably oriented polarizer.

Abstract: ABSTRACT      The present invention is directed to a method of minimising about currents in electrochemical devices which have a plurality of cells connected, at least in part, is series and which have a common electrolyte which is fed to or removed from at least two of the cells as a shared electrolyte from a common manifold vis individual inlet of outlet channels, respectively , whereby an electrical electrolytic conductive bypass pathe is created around such cells andthrough said shared electrolyte, resulting in undersirable about currents. This method involves providing electrolyte tunnels which connect the individual inlet of outlet channels and applying a protective current through said electrolyte tunnels and thus through said shared electrolyte, the protective current being of a magnaitude which effectively at least reduces said about currents. Thus, a single proactive current may be applied such that about currents are minimized, and preferably are totally eliminated, The present invention is also directed to an electrochemical device having means adapted for applying the protective current thereto.

Abstract: Abstract A high voltage fuse for interrupting a wide range of currents and especially suited for low current interruption is disclosed.  The fuse is comprised of a fuse element having a first and a second plurality of portions of reduced cross-sections.  The second plurality of portions further comprise two or more parallel conducting paths some of which-carry a portion of material which has a lower melting temperature than the melting temperature of the material of the fuse element.  The parameters of the first and second plurality of reduced cross-section portions, the lower melting point material, and the fuse element itself are selected to adapt the fuse to provide proper protection for the various current conditions to which a high voltage transformer is subjected. The fuse element provides fast rupturing under short-circuit current conditions while also pro-viding the characteristic of withstanding relative-ly high inrush current conditions.  The fuse element further provides improved low current clear ing ability for the fuse, and a fuse which responds quickly to through fault (secondary fault) conditions in a transformer.

Abstract: Abstract of the Disclosure IMPROVEMENTS RELATING TO ELECTRIC CABLES     AND ELECTRIC CABLE INSTALLATIONS          A single-core electrical power cable for use at 400 kV for example has a relatively high-resistance inner shield located between and insulated from the central core of the cable and its low resistance metallic outer sheath.  The inner shield is kept continuous throughout the cable run of installations where, for avoidance of currents circulating in the cable sheath, the sheath continuity is broken at spaced-apart locations.  By virtue of such continuity, the inner shield provides a continuous path for         surges developed in the cable as the result of lightning strikes or switching operations thereby preventing the development of corres-ponding high transient overvoltages at the outer cable sheath and particularly at the discontinuities therein. It is thus possible to dispense with the surge voltage limiters previously required to be coupled to the outer cable sheath at intermediate positions of cross-bonded systems.
