Patent CA-2314061-C (CA)
Title: Reservoir management system and method
Inventor: TABANOU JACQUES R
IPC: E21B47/12
Filed: 2000-07-18
Granted: 2005-02-08
Abstract: An apparatus and a method for controlling oilfield production to improve efficiency includes a remote sensing unit that is placed within a subsurface formation, an antenna structure for transmitting power and communicating signals to the remote sensing unit and for receiving communication signals from the remote sensor, a casing joint having nonconductive "windows" for allowing an internally located antenna to communicate with the remote sensing unit for those embodiments in which a wireline tool is being used to communicate with remote sensing unit, and a system for obtaining subsurface formation data and for producing the formation data to a central location for subsequent analysis. The remote sensing unit is a standalone sensor that is placed sufficiently far from the wellbore to reduce or eliminate effects that the wellbore might have on formation data samples taken by the remote sensing unit. The remote sensing unit is an active device with the capability of responding to control commands to determine certain subsurface formation characteristics such as pressure or temperature, and transmitting corresponding data values to a wellbore tool. Some embodiments of the remote sensing unit include a battery within its power supply. Other embodiments include a capacitor for storing charge.  The embodiments that include the capacitor receive RF power that is converted to a DC signal for storing charge on the capacitor. The charged capacitor then acts as a power source to provide power to the internal circuitry of the remote sensing unit. When the charge is depleted to a specified point, the remote sensing unit stops transmitting to prompt the wellbore tool to transmit additional RF power to recharge the capacitor. This particular embodiment allows the remote sensing unit to be operable well after any charge of a battery would have been depleted rendering the remote sensing unit inoperable. An inventive method therefore includes providing RF power to the remote sensing unit to wake it up and to place it into an operational mode. The method further includes receiving modulated data values from the remote sensing unit that are then transmitted to the surface where operational decisions for the well may be made. In one embodiment of the invention, the subsurface formation data values are transmitted to a central location for analysis.

Abstract: The invention relates to an environmentally friendly method for generating energy from natural gas. Through the combustion of the natural gas with a mixture comprising substantially oxygen and CO2, a number of advantages are achieved with regard to the emission of CO2 and NOx. According to the invention, the CO2-rich product gas is injected into a natural gas reservoir from which natural gas has been extracted. By the underground replacement of natural gas by CO2, a pressure drop in the natural gas reservoir can be controlled, so that subsidence is prevented.  Additionally, in this manner, the emission of CO2 is reduced or even wholly prevented.

Title: Method and apparatus for delivering metallurgically improved molten metal
Inventor: JACOBS ROSS A
IPC: C21C7/00
Filed: 2000-05-17
Granted: 2008-11-25
Abstract: A method and an apparatus for enhanced metallurgical processing of molten metal includes an enclosable ladle chamber (23) for reducing the escape of heat during transport of the ladle from a manufacturing vessel such as a furnace (13) to an intermediate processing (15) or refining station or durin g processing or transport to a receptacle vessel such as a tundish (17). The method comprises introducing a refractory body into the ladle chamber (23), the body having an adjusted specific gravity having a reduced steel ballast to refractory material ratio that is less than required for a specific gravity required to buoyantly support the body in the molten metal. Preferably, the ratio provides a specific gravity greater than the specific gravity required to buoyantly support the body entirely in the slag layer. The method include s enclosing the ladle (22) for example, with a lid (90) and maintaining said refractory body in said ladle until substantially termination of the dischar ge of the molten metal from the vessel. Preferably, the method also includes intermediate refining such as introducing a balancing composition to the lad le before enclosing. The ratio of steel ballast and refractory material used to achieve the preferred specific gravity may also be adjusted in conjunction with other temperature-resistant or corrosion-resistant changes to the refractory body. For example, high temperature alumina may be used as a refractory material in a higher degree than in previously known bodies, a hi gh temperature cement may be used to join the refractory material and ballast components, and a non-wetting agent made of carbonaceous or siliceous materi al may reduce deterioration of the body during the extended period of steel and slag contact in the ladle.
