Title: Rate-controlled multi-class high-capacity packet switch
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 2000-01-21
Abstract: A high-capacity switch for transferring variable-sized packets under rate control is described.      The packets are divided in the switch into segments of predetermined equal size. The packets are reconstructed before egress from the switch. The switch serves traffic of different classes of service, but the class of service distinction is relevant only at the ingress or egress modules. The switch control is preferably centralized to facilitate effective sharing of the inner capacity of the switch. The control is based on modulating the ingress/egress rate according to traffic load, the central control being unaware of the class of service disposition of the traffic it controls. The advantage is a high capacity switch adapted to transfer variable-sized packets with guaranteed rate control.

Title: Positioning of the tubing string in a steam injection well
Inventor: ITO YOSHIAKI
IPC: E21B43/24
Filed: 2000-07-13
Abstract: A steam-assisted gravity drainage process, involving a co-operating pair of closely spaced, horizontal steam injection and liquid production wells, is modified as follows: .cndot. during the initial circulation phase, the tubing string is landed at the toe of the injection well; and .cndot. during the following injection phase, the tubing string is landed at the heel or intermediate the heel and toe. It has been found that steam preferentially leaks into the reservoir at heel and toe due to pressure drop arising from friction effects through the annulus, between the tubing string and screened liner. So the steam delivery point through the tubing string during the circulation phase is located at the toe, but it is retracted to the heel or to between heel and toe for the injection phase, to shorten the annulus and thereby lessen the pressure drop.

Patent CA-2324319-A1 (CA)
Inventor: CUNNINGHAM EDMUND C
IPC: E21B43/12
Filed: 2000-10-25
Abstract: A hydraulic submersible rotary pump and drive assembly is provided which can be deployed and recovered through production tubing or casing using hydraulic metal tubing lines. The assembly can be used in conventional oil and gas well bores, but is particularly advantageous in slant or horizontal oil and gas well bores for artificial fluid lift or water injection. It eliminates mechanical drive shafts running from surface to a bottom hole rotary pump, and allows rotary pumps to be changed without pulling out the production tubing. The drive assembly incorporates a pored torque neutralising connector sub to attach a suitable hydraulic drive motor to a selected submersible rotary production pump. The pump drive also incorporates the use of a conventional pump seating nipple in the production tubing and seating cup assembly on the drive to seal the pump discharge from the pump suction within the tubing. In an alternate version, the assembly is capable of being used with a pack-off assembly (rather than the pump seating nipple) to seal against a production casing or open hole when it is desirable not to use production tubing.
