Patent CA-2369860-A1 (CA)
Title: Sand screen with active flow control
Inventor: ZISK EDWARD J JR
IPC: E21B43/08
Filed: 2002-01-25
Abstract: Apparatus and methods are disclosed for actively controlling the flow of hydrocarbon fluids from a producing formation at the downhole sand screen.   A preferred embodiment of the invention provides a fluid flow annulus within the production tube inside of the screen in a first flow control configuration, fluid passing through the screen is required to flow along the annulus to find a flow aperture into an interior flow bore. A static flow control device within the annulus between the sand screen and a first flow aperture dissipates flow energy by forcing the flow through a restricted area that helically winds about the flow annulus. Dissipation of the flow energy increases the pressure reduction from the screen into the production bore and reduces the flow velocity. In a second flow control configuration, flow control structure within the flow annulus obstructs all flow along the annulus. A third flow control configuration removes all flow restrictions within the flow annulus.

Title: Method for identification of shallow water flow hazards using marine seismic data
Inventor: HUFFMAN ALAN ROYCE
IPC: G01V1/38
Filed: 2000-06-07
Abstract: The problem of detecting sedimentary formations having an abnormally high fluid pressure that are underneath a relatively impermeable formation, (118), having normal fluid pressures is addressed. At shallow depths, a formation with abnormally high fluid pressure has a shear velocity that is close to zero, (134), and is thus significantly different from the shear velocity of overlying sediments, (118). The high shear wave-velocity contrast is detected by measuring, (116), a change in the amplitude of seismic waves reflected from the top of the abnormally pressured formation, (130). This may be done by an amplitude versus offset (AVO) analysis of the reflected amplitudes of compressional or shear reflections. Measurements of the amplitude of reflected shear waves from a formation, (118), at some depth below the anomalous zone are may also be used to detect the presence of abnormally pressured intervals with low shear velocity, (138), and high shear wave attenuation.

Title: Conveyor roller nip point automatic protection device
Inventor: DUBE BERT Y
IPC: B65G43/00
Filed: 2002-04-23
Abstract: In industrial belted conveying systems, it is common to have a pull chord extending longitudinally along the conveyor, sometimes one chord on each side of the conveyor, said chord being attached to a trip mechanism, or safety switch. A  number of serious accidents have occurred in the industry due to unprotected nip points at the return idlers under these conveyors. Accidents were the result of these pull chords not being easily accessible for manual activation of the safety features. In this invention, a primary pull chord is placed near the nip point, inserted through guides, and linked to one or more secondary longitudinal pull chord(s). The primary pull chord may be sleeved with a semi-rigid, pliable rod as additional support between the guides. Further, this semi-rigid rod may be encapsulated in a lightweight foamy tube to give it bulkiness. In the event of an inadvertent incident, the primary pull chord is entrained into the nip point, pulling the secondary longitudinal pull chord which then trips the safety switch, automatically disabling the conveyor drive.

Abstract: A presence management system is described whereby connections between watching parties and watched parties in a multiple access communications network are managed. When the presence management system receives a contact request from a watching party it determines whether the required watched party is available for contact. The system then provides information about this to the watching party who made the request. The presence management system chooses the best mode of communication (e.g. email or fax) taking into account the watched parties preferences and details about the facilities available to the watching party. If the presence management system informs the watching party that the watched party is unavailable, the watching party is able to set up a monitor.  In determining whether the required watched party is available for contact, the presence management system uses stored information about the watched party, information about the required connection (e.g. size and type) and also rules. In addition, information about events from the multiple access network are used e.g. geographical location of watched party mobile phones.  Advantageously, watched parties or watching parties are services. For example, a watching party is a conference call service which monitors watched parties and sets up a conference call when the watched parties are available. A  watched party may also be a service, such as a ticket agency. Watching parties can set up monitors using the presence management system to be alerted when new tickets are available from the agency.
