Patent CA-2314061-A1 (CA)
Title: Reservoir management system and method
Inventor: TABANOU JACQUES R
IPC: E21B47/12
Filed: 2000-07-18
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.

Patent CA-2347514-A1 (CA)
Inventor: BENTE PAUL
IPC: B01J3/00
Filed: 2001-05-14
Abstract: A fractionated sample collection process and device having at least one pressurized chamber used to gather and store liquid samples generated from a flow stream containing a mixture of highly compressed gas, compressible liquid, or supercritical fluid and a relatively incompressible liquid. A bank of multiple collection chambers is secured together in a frame to form a cassette unit. Each collection chamber may house a replaceable liner such as a test tube vial, to hold a fractionated liquid phase sample. After filling with sample, a collection chamber is returned to a clean state and ready for refilling with a new sample by manually or automatically replacing the liner. The separation and collection process partitions the liquid phase, containing modifier and dissolved sample components from the gaseous phase components upstream of the collection chamber so that liquid phase has controlled discharge into the collection chamber. Movement and replacement of collection chamber liners to capture liquid fractions can be manually or robotically controlled. Automatic replacement of liners increases the speed of production as well as quality control by preventing drips and spills and possible carryover contamination of samples. The system provides extremely efficient and controllable gas and liquid phase separation, thereby effecting up to 98% injection recovery. The collection process is environmentally friendly and economical because it eliminates additional uses of solvents to collect, trap, or recover fractions. In addition, the process eliminates any additional cleaning solvents associated with mechanical phase-separation devices. The invention promotes high speed, high volume, and high quality fractionated SFC sample production.

Abstract: A strap winch device assembly for fitting on a flat bed open truck trailer, to enable a truck driver to remote actuate this load tightening system without leaving his truck cab, in periodic fashion. A number of these winch devices are connected to a single fore and aft drive shaft, which extends along the side of the trailer. The drive shaft is driven by a motor to tighten any straps that loosen when the trailer is in motion over the road, as trailer load distribution typically shifts during road trailer, due to road-induced vibrations. A clutch mechanism is provided in the winch device, to prevent the motor from overheating once a set tightening torque threshold level has been reached.

Abstract: A process for inducing direct somatic embryogenesis and secondary embryogenesis in monocotyledonous plant cells and rapidly regenerating fertile monocotyledonous plants is provided. In a first step, embryogenic monocotyledonous plant cells are cultured under conditions conducive to direct formation of primary embryos without an intervening callus stage, at least until at least one primary embryo reaches the globular developmental stage and no longer than the coleoptilar stage. In a second step, one or more primary embryos from the first step are cultured under conditions conducive to induction of secondary embryo formation, until secondary embryogenesis is detected. In a third step, one or more secondary embryos from the second step are cultured under conditions conducive to regeneration of plantlets from the secondary embryos. Also provided is a process for inducing direct somatic embryogenesis in monocotyledonous plant cells and rapidly regenerating fertile monocotyledonous plants, without secondary embryogenesis. In a first step, embryogenic monocotyledonous plant cells are cultured under conditions conducive to direct formation of primary embryos without an intervening callus stage, at least until at least one primary embryo reaches the globular developmental stage. In a second step, one or more primary embryos from the first step are cultured under conditions conducive to regeneration of plantlets from the primary embryos. Also provided is a process for inducing direct somatic embryogenesis and organogenesis in monocotyledonous plant cells and rapidly regenerating fertile monocotyledonous plants. Globular-stage embryos obtained by this same method for direct somatic embryogenesis are cultured under conditions conducive to induction of organogenesis, or until adventitious shoots are detected. One or more of the new shoots are then cultured under conditions conducive to regeneration of plantlets. Also provided is a process for inducing somatic embryogenesis in monocotyledonous callus cells, suspension cells, or microspore-derived embryos, and rapidly regenerating fertile monocotyledonous plants. In a first step embryogenic monocotyledonous callus cells, suspension cells or microspore-derived embryos are cultured in or on a culture medium comprising auxin, cytokinin, and polyamine in amounts effective to cause induction of embryo formation, the cytokinin being present in greater proportion than the auxin, at least until at least one embryo reaches the globular developmental stage. In a second step, one or more globular-stage embryos from the first step are cultured under conditions conducive to regeneration of plantlets from the globular-stage embryos. Fertile monocotyledonous plants produced according to the processes of the invention are also provided.
