Title: Reservoir management system and method
Inventor: TABANOU JACQUES R
IPC: E21B43/00
Filed: 2000-07-18
Granted: 2006-11-21
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: An aerator or destratifier used to provide Oxygen to standing or less active bodies of water. The aerator has a non-floating internally driven motor within a non-floating sealed drum. The drum and motor are supported by a support frame attached to floatation devices. A plurality of elliptically shaped paddles are externally affixed to the exterior surface of the non-floating drum. Rotation of the drum by the internal motor and gearbox causes rotation of the plurality of paddles affixed to the drum exterior. The plurality of paddles cause agitation of the body of water and allow Oxygen to be dissolved therein.

Granted: 2003-10-21
Abstract: In a plain bearing for the transmission of high axial forces and great flexural moments with slight relative movements the one co-operating bearing component has an annular rib which engages into an annular groove provided on the other co-operating bearing component. The annular rib which can be of an outwardly convergent trapezoidal cross-section is provided with anti-friction linings on its free side faces and possibly peripheral faces. The anti-friction linings, like the co-operating bearing component in question, in particular an outer ring carrying the annular rib, can be subdivided segment-like. The segments can then be released individually from their composite assembly and maintained, in particular provided with new anti-friction linings. A preferred use of this plain bearing is the arrangement thereof between a pylon-supported machine head and the pylon head of a wind power installation.

Abstract: A chill tube having a double T-shaped inner and outer cross-section in beam blank format is encased in a water-guiding jacket adapted to its outer contour while forming a water gap. The wall thickness of the chill tube in the rounded transition regions from middle crosspieces, which face each other head to head and are drawn in towards the longitudinal axis, to the neighboring crosswise positioned flanges is dimensioned at least partially smaller than in the remaining wall sections. The reduction in wall thickness is implemented by longitudinal hollow recesses. These recesses extend only in the height range of the bath level. Into the cross-sectional regions which are formed by the outer contour of chill tube as well as the inner contour of the water-guiding jacket, filler pieces are incorporated, which are adapted to this cross-section.
