INTERFEROMETRY-BASED DATA REDATUMING AND/OR DEPTH IMAGING

摘要

Processing measurements to create “reflectivity” data at a datum for a target using Joint Point-Spread Functions. The “reflectivity” data can be an image or an extended image. The methods can create single reflectivity data from measurements from multiple experiments, or multiple processed datasets via different processing routes from measurements from a single experiment, or measurements from a single experiment with multiple simultaneous sources.

1. A method for processing measurements at a datum received by at least one receiver of a wavefield generated by at least one source wherein the wavefield is disturbed by a target, the method comprising:
receiving at least two sets of measurements of the wavefields affected by the target (310, 410, 510, 610, 1010) from the at least one receiver; constructing a Joint Point Spread Function system using the at least two sets of measurements (320, 420, 520, 620, 1020); and obtaining reflectivity data by multi-dimensional deconvolution of the Joint Point Spread function system (330, 430, 530, 630, 1030).
