104 | A method and system for controlling a travelling body so as to move forward along a predetermined route | EP91305636.2 | 1991-06-21 | EP0466348A1 | 1992-01-15 | Fujimori, Isao; Matsumori, Shigeru; Kano, Takashi; Sumi, Toshio |
When controlling a travelling body so as to move forward the travelling body along the predetermined route, the distance and direction of deviation of a body of the travelling body from the predetermined route are measured, the above measured distance and direction of deviation of the body from the predetermined route are inputted as an observed value into an antecedent operation part in which the membership functions corresponding to distances of deviation of the body from the predetermined route are prestored. Then an operation of grade at the antecedent, namely a degree that an operator has a feeling that the above deviation is small or medium or large is performed. An operation of manipulated value in the consequent is performed by inputting the obtained grade into a consequent operation part in which the membership functions corresponding to manipulated values are prestored. The obtained manipulated value is outputted into the steering means. The steering means is controlled according to the manipulated value. By means of the above mentioned method, an operator can automatically control the travelling body so as to move forward along the predetermined route without the help of veteran operator. |

Un transducteur acoustique (102) comprend une surface courbe (102) adaptée aux surfaces interne (108) ou externe d'une surface cible (100), telles que des tiges cylindriques de forage. Une séquence d'impulsions d'excitation provoque l'émission par le transducteur d'une série d'impulsions de haute-fréquence (308) vers les tiges tubulaires. On détermine les caractéristiques des surfaces tubulaires, y compris la localisation, la superficie et la profondeur de tout creux dû à la corrosion des surfaces tubulaires, sur la base d'une forme d'onde d'écho pleine. Un Système Expert normalisé analyse la forme d'onde pleine des impulsions d'écho réfléchies par les tiges tubulaires afin de déterminer les caractéristiques les plus probables des surfaces ayant produit la forme d'onde d'écho pleine. Plus spécifiquement, le Système Expert utilise des connaissances au sujet des propriétés acoustiques du milieu cible et des contraintes sélectionnées par un expert afin de déterminer quelles structures de signaux sont significatives et quelles structures de signaux sont trompeuses. L'invention concerne également le prétraitement et la transmission d'informations. Elle réduit la quantité absolue d'informations transmises sans réduire la quantité transmise d'informations significatives. Elle permet de transmettre davantage d'informations significatives que les systèmes conventionnels de transmission. Elle permet également de diminuer le traitement d'informations à la destination. | ||||||

A system for detecting fluid influxes and losses can include a sensor which detects floating vessel movement, and a neural network which receives a sensor output, and which outputs a predicted flow rate from a wellbore. A method can include isolating the wellbore from atmosphere with an annular sealing device which seals against a drill string, inputting to a neural network an output of a sensor which detects vessel movement, the neural network outputting a predicted flow rate from the wellbore, and determining whether the fluid influx or loss has occurred by comparing the predicted flow rate to an actual flow rate from the wellbore. Another method can include inputting to a neural network actual flow rates into and out of the wellbore, and an output of a sensor which detects vessel movement, and training the neural network to output a predicted flow rate from the wellbore. | ||||||

108 | METHOD AND APPARATUS FOR CHEMOMETRIC ESTIMATIONS OF FLUID DENSITY, VISCOSITY, DIELECTRIC CONSTANT, AND RESISTIVITY FROM MECHANICAL RESONATOR DATA | EP05725578 | 2005-03-15 | EP1725968A4 | 2012-01-25 | DIFOGGIO ROCCO; REITTINGER PETER W |
The present invention provides a chemometric equation to estimate fluid density, viscosity, dielectric constant and resistivity for a formation fluid sample downhole. The chemometric estimates can be used directly as estimated values for fluid density, viscosity, dielectric constant and resistivity for a formation fluid sample downhole. The chemometric estimates can also be plugged into a Levenberg-Marquardt (LM) non-linear least squares fit, as an initial estimate of the parameter to be estimated by the LM fit. If the initial parameter estimate is too far from the actual parameter values, the LM algorithm may take a long time to converge or even fail to converge entirely. The present invention estimates an initial value of a parameter that provides a high probability that the LM algorithm will converge to a global minimum. | ||||||

A method of optimizing performance of a well system utilizes a neural network. In a described embodiment, the method includes the step of accumulating data indicative of the performance of the well system in response to variable influencing parameters. The data is used to train a neural network to model an output of the well system in response to the influencing parameters. An output of the neural network may then be input to a valuing model, e.g., to permit optimization of a value of the well system. The optimization process yields a set of prospective influencing parameters which may be incorporated into the well system to maximize its value. | ||||||
110 | SPECTRAL POWER RATIO METHOD AND SYSTEM FOR DETECTING DRILL BIT FAILURE AND SIGNALING SURFACE OPERATOR | EP01993745.7 | 2001-11-07 | EP1340069B1 | 2011-10-05 | SCHULTZ, Roger, L.; DE JESUS, Orlando; OSBORNE, Andrew, J., Jr. |
An apparatus and method for monitoring and reporting downhole bit (108) failure. Sensors (106) are located on a sub assembly (104) (which is separate from the drill bit (108) itself but located above it on the drill string (102)). Data from the sensors (106) are collected in blocks, then analyzed in the frequency domain. The frequency domain is divided into multiple bands, and the signal power in each band is compared to that of another band to produce a ratio of powers. When a bit (108) is operating at normal condition, most of the spectral energy of the bit vibration is found in the lowest frequency band. As a bearing starts to fail, it produces a greater level of vibration in the higher frequency bands. This change in ratios is used to determine probable bit (108) failure. | ||||||

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. | ||||||

A drilling control system provides, in one aspect, advisory actions for optimal drilling. Such a system or model utilizes downhole dynamics data and surface drilling parameters, to produce drilling models used to provide to a human operator with recommended drilling parameters for optimized performance. In another aspect, the output of the drilling control system is directly linked with rig instrumentation systems so as to provide a closedloop automated drilling control system that optimizes drilling while taking into account the downhole dynamic behavior and surface parameters. The drilling models can be either static or dynamic. In one embodiment, the simulation of the drilling process uses neural networks to estimate some nonlinear function using the examples of input-output relations produced by the drilling process. | ||||||

An expert system is included in a downhole processor designed to acquire and process NMR data downhole in real time. The downhole processor controls the acquisition of the NMR data based at least in part on instructions transmitted downhole from a surface location and at least in part on evaluation of downhole conditions by the expert system. The downhole conditions include drilling operation conditions (including motion sensors) as well as lithology and fluid content of the formation obtained from other MWD data. The wait time, number of echos, number of repetitions of an echo sequence, interecho time, bandwidth and shape of the tipping and refocusing pulses may be dynamically changed. |
