oa Processing Land Broadband Data: Challenges that Oman Surveys Present and How they are Addressed

A set of land broadband seismic data from Oman is presented. They belongto a few dense wide azimuth surveys which were recently recorded using a 1.5Hz-86Hz sweep.We show how the quality of the broadband signal can be effectively controlled at each processing step in such surveys. The aspects in which the low frequencies differ from standard frequencies are presented and the benefits of applying octave dependent processes are discussed. The ability to acquire and image high quality low frequencies on marine data sets has been demonstrated for sometime. We illustrate via these examples that this goal can also be achieved on land data.
