High Density 3D – Improved Imaging in Complex Geology

A14 HIGH DENSITY 3D – IMPROVED IMAGING IN COMPLEX GEOLOGY Abstract 1 3D seismic surveys have seen increasing usage since the mid-1970s and have been recognized as a primary reason for increased oil exploration success in the last two decades. In the early years most survey designs were restricted by a combination of cost equipment limitations and a lack of understanding of the benefits of good spatial sampling and good offset sampling. Also due to some of the above limitations many surveys were designed with a narrow range of azimuths. Recently there have been significant improvements in technology that now
