2D seismic acquisition using different source weights integrated in the stack

Seismic imaging improvement have driven most of the efforts in the search of solutions as well as research and technology development. Paleozoic basins are in evidence in Brazil due to the great territorial area and lack of available information. These basins have a great potential for oil and gas accumulations. The existing discoveries have been mainly developed for power generation in the last years. Development of new technologies or techniques in the oil and gas sector usually requires high investment therefore cost reduction can be considered as a major improvement along enhance in seismic imaging quality. In this work we will discuss the results of a 2D seismic acquisition test using multi-weight source and the quality of the data with the different source sizes. The improvement associated to the stack of all the sources sizes together is also a significant result of this test.
