    摘要: The present invention provides a method and system for processing an input seismic record to suppress noise energy, for example multiple energy, and to enhance signal. A primary signal component is determined from an input seismic record. A residual record is obtained from the input seismic record and the determined primary component record, for example, by determining a difference of the two records. A next primary signal component record is then obtained from the residual record. The primary component record and the next primary component record are combined to form a reconstructed record. A subsequent residual record may then be obtained and further primary signal components extracted.

    摘要: A method for completing a subterranean formation includes conveying a perforator assembly into a borehole drilled in the subterranean formation. The perforator assembly includes at least one shaped charge and at least one tracer package that includes at least one fluid production tracer material and a tracer injector. The method further includes forming at least one tunnel in a production structure by detonating one or more shaped charges and injecting the at least one fluid production tracer material into the formation using the tracer injector after the detonation of the at least one shaped charge. The at least one production tracer material physically associates with at least one resident fluid in the subterranean formation.

    摘要: The present invention provides a method and system for distributed residual tomographic velocity analysis using dense residual depth difference maps. Prestack seismic imaging is performed using an initial velocity field and interpreted horizons. A residual depth difference is estimated referenced to fixed offset and all horizons. Residual depth difference maps are computed for each offset and each horizon. The residual depth difference maps are back projected to determine slowness perturbation. The initial velocity model may be converted to slowness and the estimated slowness is composited therewith to produce a new slowness volume. The new slowness volume is converted to a new velocity volume for performing prestack seismic imaging. This process is repeated until the slowness perturbation is negligible or reaches a predetermined threshold.
