Patent CA-2121179-A1 (CA)
Title: Pump for evacuating water from a gas producing well by pumping the water to a lower water absorption zone
Inventor: LEVESQUE JOSEPH
IPC: E21B34/06
Filed: 1994-04-13
Abstract: Water accumulating within gas producing wells is typically pumped to the surfacewhere it is contained and transported off-site. It has been proposed instead to pump such accumulated water deposits to a lower water absorption zone below the gas producing zone and thus dissipate the unwanted water into the surrounding earth. To date, however, a practical pumping device to accomplish this end has not been readily available. Such a device is disclosed in the specification herein and is comprised of an outer barrel contain-ing a piston. The piston consists of a hollow mandrel shaft upon which is mounted a plural-ity of packing rings with bushing material at either end. End plugs are threaded onto each end of the mandrel compressing and expanding the packing rings sandwiched therebetween. Thus the clearance between piston and barrel may be adjusted to obtain the best pumping performance and to accommodate normal barrel wear. A pair of check valves, one at ei-ther end of the pump barrel and operating in opposition during normal use, control the flow of water from one zone to the other. A well is drilled through a gas producing zone, through one or more substantially water impervious zones to a water absorption zone. The well is cased and perforated adjacent the gas producing zone and the water absorption zone. A first check valve is installed in the bore of a well packer and the packer installed in the well casing between the water absorbing zone and the impervious zone immediately above. The pump barrel is sealingly connected to the packer at one end and the pump piston, via a second check valve, is connected to a sucker rod string and the sucker rod string to a surface pump jack. On the upward stroke of the piston, the hollow mandrel is charged with water. On the downward stroke the mandrel is discharged and the water dissipated through the casing perforations into the water absorption zone.

Patent CA-2124528-A1 (CA)
Inventor: OSBORNE ROBERT
IPC: D04C1/12
Filed: 1994-05-27
Abstract: In an electric cable or other elongate body, a tubular textile braid comprises two sets of yarns each made up of a plurality of synthetic monofilaments, the yarns of the two sets extending in opposite directions around the axis of the braid (and so corresponding to upper and lower yarns in the braiding machine) differing in twist to an extent such that the more twisted yarns have their tensile strength increased by at least 10% but do not have their cover in the braid decreased by more then 25%, both by comparison with an otherwise identical yarn having the same twist of those of the less twisted set.  Preferably the twist in the upper yarns is zero.     The invention allows higher production speed and reduced down-time without significant loss of cover, because the small extra twist in the lower yarns gives them better abrasion resistance to withstand passage through their greater exposure in the braiding  machine.
