In this work, spoke about the importance of 3D seismic data compression for the petroleum industry, it is known that the processing and storage of these data is always a challenge in large oil companies, to optimize the storage time and to store a number Information. Some tools are presented for the processing and storage of data in the wavelet domain. The proposal presented is based on the Peano function and the 1D wavelet transform. The storage system aims to optimize the computational space, both for storage and for data transmission. It is necessary for this, the application of the Peano Function to linearize the information with maximum concentration of neighboring points and the wavelet transform 1D to decompose it. These applications allow the extraction of relevant information for the storage of the data with a lower computational cost and a minimum margin of error when comparing the data, original and processed, that is, there is little loss of quality when applying the presented processing system. The results obtained from the extracted information can be displayed on the screen in real time. The image processing programs via Peano Function and the Wavelet 1D Transform were developed in C ++ language, allowing a direct exchange of information between them and the user.
