Patent CA-2818293-A1 (CA)
Inventor: YANG PETER
IPC: E21B43/24
Filed: 2013-06-07
Abstract: A method for remediation of at least one cold spot in a producer well in a Steam Assisted Gravity Drainage (SAGD) process to increase hydrocarbon recovery from a hydrocarbon reservoir, wherein the SAGD process occurs at a site including an injection well, a production well and a steam chamber. The method includes shutting the production well and maintaining or increasing steam injection through the injection well until pressure in the steam chamber increases. The production well is then resumed while continuing steam injection at rates for normal SAGD or greater until reservoir pressure reaches normal operational pressure.  Optionally, the injection/production is adjusted to return to normal SAGD  operation.

Title: An unbonded flexible pipe
Inventor: KASSOW KRISTIAN
IPC: F16L11/08
Filed: 2012-01-03
Abstract: The invention relates to an unbonded flexible pipe for sub sea transportation of fluids. The pipe has a length and comprises a tubular inner sealing sheath (2) defining a bore and an axis (8) of the pipe. In a pipe length section it comprises a second sealing sheath (9) surrounding the inner sealing sheath (2) and forming an annulus between the inner sealing sheath and the second sealing sheath. The annulus provides a primary maintaining passage along the length of the pipe length section with a first and a second end. The pipe comprises at least one secondary maintaining passage (5) along the length of the pipe with a first and a second end. The secondary maintaining passage is arranged with an axial distance which is larger than the axial distance of the inner sealing sheath (2). The first end of one of the primary and the secondary maintaining passages is arranged as an input end for a maintaining fluid and the first end of the other of the primary and the secondary maintaining passages is arranged as an outflow end for the maintaining fluid, and the primary and the secondary maintaining passages are in fluidic connection with each other at their second ends to provide a pathway for the maintaining fluid. The pathway for a maintaining fluid makes it possible in a simple and effective manner to keep the corrosion of elements - such as armouring elements in the annulus - relativly low, and accordingly the duration of the unbonded flexible pipe can thereby be increased.

Abstract: A system for assessing energy usage reads read at least one computer-aided design (CAD) file relating to the architecture of a facility and extracts information from the CAD file for use in determining static energy characteristics corresponding to the architecture of the facility, acquires information for use in determining dynamic energy characteristics of the facility, and calculates a predicted energy usage of the facility based at least in part on the static and dynamic energy characteristics. The system further acquires data from at least one sensor configured to measure actual energy usage of the facility in real-time and calculates the actual energy usage of the facility. When the actual energy usage exceeds the predicted energy usage, the system transmits an alert to a user and determines corrective measures to reduce energy usage.

Patent CA-2846907-A1 (CA)
Inventor: INGLE MICHAEL E
IPC: E05B47/00
Filed: 2014-03-17
Abstract: A time-locking container to limit the compulsive overuse of objects and substances, such as but not limited to money, food, alcohol, and tobacco. The container locks until a future date and time set by the user. The container informs the user, before it locks, of the duration of locking. If the duration exceeds a user-selectable maximum, the container waits for user confirmation, otherwise it locks after a delay. This feature prevents an accidental prolonged lockout.  While the container is locked, the user can extend, but not shorten, the duration of locking. The user can request early access, while the container is locked, subject to an unlocking delay before access is granted, a relocking delay after which access is denied, and an inhibit delay limiting the frequency of use of the early open feature. The device provides a programmable schedule, and can relock itself after a programmable delay.

Inventor: KELLY PATRICK L
IPC: A43B5/00
Filed: 2014-06-19
Abstract: In various sliding activities or sports, such as ice skating, a desired angle for the foot plane within a boot is selected. When conditions change, such as going to a different location or even changes within the original location such as temperature changes, the original foot plane angle is no longer appropriate to give the best convenience and performance results. In order to determine the more appropriate foot plane angle the friction coefficient of the surface for which the original foot plane angle existed is determined and then the new friction coefficient is measured at the new location or under the changed conditions. The change in initial friction coefficient to the new friction coefficient is then used to determine what change should be made to the foot plane angle.
