Abstract: A method, apparatus and system for acquiring seismic data is disclosed that in one aspect receives a seismic signal detected by at least one sensor in response to a seismic energy signal generated by a source at a selected location at a data acquisition unit in data that is in data communication with the sensor, receives at least one parameter of the source and/or receiver at the data acquisition unit; and generates a data block at the data acquisition unit having data representative of the received seismic signal and a header that contains data representative of the at least one parameter of the source and/or receiver. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Abstract: A method of analyzing seismic survey data in which a transfer function for a geological model is derived by ray tracing techniques applied to theoretical data and the transfer function is applied to actual survey data in order to calculate reflection points (50) and/or other attributes for each shot (42)/receiver (44) pair. The number of ray tracing calculations which have to be performed in deriving the model transfer function can thus be controlled. A sufficiently accurate transfer function can be derived using theoretical data representing substantially fewer shot (42)/receiver (44) pairs than are used in the traditional ray tracing solution applied directly to actual survey data. Attribute values for actual source (42)/receiver (44) pairs are estimated by interpolating the transfer function data.
