摘要： A method of processing seismic data, said seismic data having been obtained by: performing a plurality of sweeps, wherein each sweep comprises generating seismic signals in the earth (1) using a plurality of vibrators (4a-4d) by applying a pilot sweep waveform to each vibrator, each pilot sweep being a waveform of changing frequency; measuring the force applied to the earth by each vibrator to determine a measured force waveform; and measuring the seismic signals at one or more locations (5a-5e) remote from the vibrators; said method comprising: filtering the measured force waveform to remove harmonics of the pilot sweep and thus determining a filtered force waveform; generating an inversion operator from the filtered force waveform for each vibrator; and applying said inversion operator to the measured seismic signals to determine the contribution of each vibrator to the seismic signals.

摘要： The invention relates to a method of correlating two or more overlapping well logs generated by a well logging device which, in use, is positioned in a well and is mounted to an elongate member extending along the well to the surface, movement of the elongate member at the surface controlling movement of the logging device along the well. The method comprises: (a) receiving sets of logging data for two or more spatially overlapping logs generated by the logging device, each set comprising measures of a characteristic of the well at longitudinally spaced positions along the well; (b) receiving measurement data for the period or periods of log generation, the measurement data comprising measurements of the load on the elongate member and measurements of the surface position of the elongate member; and (c) correlating the sets of logging data by determining an elongate member compliance which corrects the positions of the measured well characteristics. The corrections in step (c) are performed on the basis of a correction function which relates the position of the logging device to at least (i) the measured load on the elongate member, (ii) the measured surface position of the elongate member, and (iii) the compliance of the elongate member.

摘要： Methods and apparatus are described for compressing seismic data. The data compression is achieved by splitting the data into subsets and applying requantization levels to those subsets which depend on a number representing the subset and on time. Further error criteria ensure that the error introduced by the data compression does not affect the data in a time window representing the listening time. The compression ratio can be improved by applying data encoding techniques to the subsets.

摘要： A system for drilling a cavity in a medium includes a drill bit (130), a processor (230), and a controller (190). The drill bit rotates in the medium and removes at least a portion of the medium. The processor may be configured to receive a first set of data representative of a variable rotational speed of the drill bit during a length of time in the medium, and determine, based at least in part on the first set of data, a first resonant frequency of the variable rotational speed of the drill bit. The controller may be configured to receive a second set of data representative of the first resonant frequency of the variable rotational speed of the drill bit, and vary the force applied to the drill bit based at least in part on the second set of data.
