Patent CA-2326995-A1 (CA)
Title: Rotating casing assembly and method
Inventor: CABOT BERNARD
IPC: E21B33/14
Filed: 2000-11-28
Abstract: It is common practice to rotate casing in shallow holes (to approx. 1000m). This has been found to noticeably enhance the bond between the casing and cement and wellbore wall and cement and to decrease the chance of microchannelling along the annulus. The rotating casing assembly and method, as described herein, allows for rotation of the casing at any depth. Only the lower portion is rotated. This lower portion is generally that portion crossing the production zone. This method is extremely economical compared to other methods and requires no additional rig time or surface equipment. The casing is driven to rotate by the energy of the fluid being pumped through the casing and across vanes in the casing.

Inventor: HILL EDWARD
IPC: H02N10/00
Filed: 2000-02-21
Abstract: MEMS structures are provided that compensate for ambient temperature changes, process variations, and the like, and can be employed in many applications.  These structures include an active microactuator (105) adapted for thermal actuation to move in response to the active alteration of its temperature. The active microactuator may be further adapted to move in response to ambient temperature changes. These structures also include a temperature compensation element (205), such as a temperature compensation microactuator or frame, adapted to move in response to ambient temperature changes. The active microactuator and the temperature compensation element move cooperatively in response to ambient temperature changes. Thus, a predefined spatial relationship is maintained between the active microactuator and the associated temperature compensation microactuator over a broad range of ambient temperatures absent active alteration of the temperature of the active microactuator. In an alternative embodiment wherein the active microactuator is suspended within a frame above the substrate, the MEMS structure holds at least a portion of the active microactuator in a fixed position relative to the substrate over a broad range of ambient temperatures absent active alteration of the temperature of the active microactuator.

Abstract: A diagnostic tool includes a security system which prevents the unauthorized downloading of updated software. In one embodiment, a first external storage device includes a first security signature and is electrically coupled to the diagnostic tool. A second external storage device includes software and is also electrically coupled to the diagnostic tool.  When a second security signature located within the diagnostic tool is the same as the first security signature included within the first external storage device, the diagnostic tool downloads the software into an internal storage device located within the diagnostic tool. In another embodiment, an external storage device includes software and is electrically coupled to the diagnostic tool.  Upon initial use, a first security signature which is the same as a second security signature located within the diagnostic tool is written by the diagnostic tool to the external storage device.  Thereafter, if a user attempts to utilize the external storage device with a different diagnostic tool, that diagnostic tool will not run the software located on the external storage device.

IPC: E21B33/035
Filed: 2001-08-20
Abstract: A downhole valve that may be opened and closed by alternatingly pressurizing/bleeding a first control line, which is in fluid communication with a first surface of an activating member, and a second control line, which is in fluid communication with a second surface of the activating member. The fluid within the control lines is the same density as the fluid found in the annulus of the wellbore. The development of a leak in the control lines therefore does not by itself result in the actuation or movement of the activating member or valve member.

Abstract: A system, software program, and method for monitoring performance of a fiber  processing apparatus that preferably is a disk refiner or a filter screen th at analyzes operating data pertaining to the operation of the apparatus to determine when a plate of the apparatus should be replaced before plate wear  undesirably affects performance. Operating data over time is analyzed to determine whether it exhibits a trend characteristic of plate wear and, if s o, a plate change recommendation is generated. In a preferred method, regressio n or piecewise linearization is utilized to determine a slope of the data and the slope is compared to a threshold. If above, below, or outside a certain value or window of the threshold, the recommendations is generated. To avoid  fluctuations in performance not due to plate wear from affecting the determination, operating data over several hours of apparatus operation is analyzed. When a plate of an apparatus is changed, an inventory of the plate s is updated. If the inventory requires replenishing, plates are ordered over a telecommunications link, such as by e-mail or FTP connection, with a remote supplier computer or system. New replacement plates can be entered into the inventory from information downloaded from a portable input device, such as a bar code scanneror the like.
