Improvements made in techniques for seismic data acquisition have led to data that are of the order of terabytes, which in turn creates the problem of data storage and transmission of them through the network. In regards to the problem of disk storage, despite the hard disk decreasing price, the improvement and reduction cost in seismic data acquisition techniques has pushed the demand for disk space to grow faster than the reduction of the hardware cost. Another important factor is the space necessary to store all hard drives, to provide security for information from these records. In order to tackle these problems this thesis presents a new technique for seismic data compression using 3D wavelet transform. It is also presented in comparison with current compression techniques which use the 2D transform.
