| 122 | OPTIMIZATION OF RESERVOIR, WELL AND SURFACE NETWORK SYSTEMS | EP02702144.3 | 2002-02-04 | EP1358394A1 | 2003-11-05 | ROSSI, David, J.; FLYNN, James, J. |
| A method and associated apparatus continuously optimizes reservoir, well and surface network systems by using monitoring data and downhole control devices to continuously change the position of a downhole intelligent control valve (ICV) (12) until a set of characteristics associated with the 'actual' monitored data is approximately equal to, or is not significantly different than, a set of characteristics associated with 'target' data that is provided by a reservoir simulator (32). A control pulse (18) having a predetermined signature is transmitted downhole thereby changing a position of the ICV. In response, a sensor (14) generates signals representing 'actual' monitoring data. A simulator (32) which models a reservoir layer provides 'target' data. A computer apparatus (30) receives the 'actual' data and the 'target' data and, when the 'actual' data is not approximately equal to the 'target' data, the computer apparatus (30) executes a 'monitoring and control process' program code which changes the predetermined signature of the control pulse to a second and different predetermined signature. A new pulse having the second predetermined signature is transmitted downhole and the above process repeats until the 'actual' data received by the computer apparatus (30) is approximately equal to the 'target' data. | ||||||

The conductors (38, 40) are preferably housed in the wall of the continuous tubing string (30) and may be electrical conductors, optical fibers, and/or hydraulic conduits. The control (34) is preferably equipped with a sensor that verifies operation and status of the device and provides the verification to the surface processor via the conductor. Contemplated controls include valves, sliding sleeves, chokes, filters, packers, plugs, and pumps. The system can be installed through the production tubing of an existing well. | ||||||
| 124 | SYSTEM AND METHOD FOR FLUID FLOW OPTIMIZATION IN A GAS-LIFT OIL WELL | EP01909683.3 | 2001-01-22 | EP1250513A1 | 2002-10-23 | BURNETT, Robert, Rex; CARL, Frederick, Gordon; SAVAGE, William, Mountjoy; VINEGAR, Harold, J. |
| A controllable gas-lift well having controllable gas-lift valves and sensors for detecting flow regime is provided. The well uses the tubing and casing to communicate with and power the controllable valve from the surface. Ferromagnetic chokes at the surface and downhole electrically isolate the tubing from the casing. A high band-width, adaptable spread spectrum communication system is used to communicate between the controllable valve and the surface. Sensors, such as pressure, temperature, and acoustic sensors, may be provided downhole to more accurately assess downhole conditions and in particular, flow regime. Operating conditions, such as gas injection rate, back pressure on tubing and position of downhole controllable valves are varied depending on flow regime, downhole conditions, oil production, gas usage and availability, to optimize production. An Artificial Neural Network (ANN) is trained to detect Taylor flow regime using downhole acoustic sensors, plus other sensors as desired. The detection and control system and method thereof is useful in many applications involving multi-phase flow in a conduit. | ||||||

| The present invention relates to a control mechanism for a horizontal drilling machine that uses a drilling rod (2) to drive a drilling lance (1). The control mechanism is provided with an input interface for receiving actual values of control variables of the horizontal drilling machine and fitted with an output unit that emits control signals to control said horizontal drilling machine. A fuzzy regulator (7) is arranged between the input interface and the output unit. Said regulator determines the control signals that control the horizontal drilling machine on the basis of the actual values of the control variables and the desired values for the control variables, using fuzzy logic and taking heuristic process values into account. The control mechanism enables a horizontal drilling device to be operated automatically and provides good line guidance and target accuracy. | ||||||

| An apparatus and method for obtaining samples of pristine formation or formation fluid, using a work string designed for performing other downhole work such as drilling, workover operations, or re-entry operations. An extendible element extends against the formation wall to obtain the pristine formation or fluid sample. While the test tool is in a standby condition, the extendible element is withdrawn within the work string, protected by other structure from damage during operation of the work string. The apparatus is used to sense or sample downhole conditions while using a work string, and the measurements or samples taken can be used to adjust working fluid properties without withdrawing the work string from the bore hole. When the extendible element is a packer, the apparatus can be used to prevent a kick from reaching the surface, adjust the density of the drilling fluid, and thereafter continuing use of the work string. The test apparatus can be mounted on a sliding, non-rotating, sleeve on the work string. | ||||||
| 130 | METHOD FOR MEASURING AND CONTROLLING THE FLOW OF NATURAL GAS FROM GAS WELLS | EP99908478.3 | 1999-02-25 | EP1060450A1 | 2000-12-20 | Ocondi, Cham |
| This method serves as both a raw data logger (36) for well operation analysis and a well event logger for well performance analysis. An improved methodology of remote event and process variable logging and data retention designed specifically to address the needs of intermittently flowing gas wells is useful for eliminating gas slippage associated with intermittent or erratic gas flow conditions, eliminating measurement errors, and lowering operating costs. The well data (1.1, 34) can be scanned in seconds for its current flow situation, and as a set of specific conditions are met, a built-in control program reacts to those conditions by shutting down the well until certain pressure criteria are met to allow the well to flow again. To maintain measurement integrity, precise event logging (1.2) of the valve positions to indicate the actual flowing period are included in the flow integration. | ||||||

| The invention concerns a sensor arrangement for controlling vehicle ventilation systems which recirculate or deliver air in dependence on the pollutant concentration in the air outside the vehicle. The sensor arrangement comprises a gas sensor element (52) whose electrical resistance decreases when reducing gases occur and increases when oxidizing gases occur. The arrangement further comprises an evaluation unit (51) whose output is connected to the ventilation system control device. In order to simplify the sensor technology of such a sensor arrangement and to configure the evaluation system such that it is less expensive, this sensor arrangement is designed so that the rise in a gas sensor signal input into the evaluation unit when the reducing gas concentration increases is quantitatively and approximately equal to the fall in the gas sensor signal input into the evaluation unit (51) when the oxidizing gas concentration correspondingly increases; so that the evaluation unit (51) determines from the gas sensor signal input thereinto the rise or fall in the gas sensor signal per unit of time; and so that the evaluation unit (51) generates a switching signal to change over the ventilation system to recirculation as soon as the determined rise or fall in the gas sensor signal per unit of time quantitatively exceeds a threshold value. | ||||||

A system for supporting the drive of an excavating type underground digging machine is provided to lighten the operator's burden so that an unskilled operator can operate the machine as well as a skilled operator. In this system for supporting the drive, output signals from a group of first sensors (12a) for measuring amount of a rocking actuator (10) for directional control and an output signal from a second sensor (12b) for measuring cutter torque hydraulic pressure are inputted into an automatic measuring section (14). These signals are adjusted in an automatic adjusting section (15) and input to a fuzzy control section. The rocking amount of an excavating cutter is calculated in a rocking amount supporting system section (16a) in response to the adjusted signal from the group of the first sensors. An optimal cutter torque control operation content is calculated in a cutter torque supporting system section (16b) in response to an adjusted signal from the second sensor, and the both results of calculation are displayed on a display output device (17). |

The method also includes applying a kernel regression model to the latent features to generate a predicted value of physical output for performing the physical process on each of the plurality of candidate objects. The method additionally includes generating a prioritization of the candidate objects based on the values of physical output. The method involves selecting fewer than all of the plurality of candidate objects on which to perform the physical process. The selected candidate objects are based on the prioritization. | ||||||
