| 147 | 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. | ||||||

| Electrical energy is produced at a remote site by converting kinetic energy from the environment. The kinetic energy may include vibrations and flow of fluid. In some embodiments the kinetic energy causes magnets to move with respect to coils in order to produce electrical energy. An anchor holds the device in place, and permits the device to be retrieved or relocated. A flexure or compliant membrane that helps determine the position of the magnets with respect to coils is defined by mechanical properties that permit oscillatory movement in response to the inputted kinetic energy. The device can be tuned to different vibration and flow regimes in order to enhance energy conversion efficiency. Further, the device may be mounted in a secondary flow path such as a side package or annular tube. | ||||||
