Seismic prospecting has been around since the 1920s and was almost exclusively [[two-dimensional]] until the mid-1980s. Three-dimensional techniques were experimented with as early as the 1940s but did not progress far until digital processing became common in the 1970s. Current worldwide seismic effort is estimated to be over 50% 3-D, and the percentage is growing rapidly. This would apply to dollar volume and/or acquisition effort. International (non-U.S.) seismic prospecting could be as high as 75% 3-D. We live in a 3-D world and now understand that 2-D seismic data is prone to many pitfalls and problems. A great advance of the last 25 years has been the development of the 3-D seismic technique, which has much more risk-reducing information content than an equivalent amount of 2-D seismic.
