More than 100,000 time line of 2D seismic data has been acquired over the years both onshore and offshore. 3D seismic data has also been acquired, mainly offshore. Details of all seismic surveys with a listing of acquisition and processing parameters and a shot point map at a scale of 1:500,000 are available. Most of these data can be obtained in the form of paper prints and films. A certain amount of digital is also available. Efforts are currently underway to have all old seismic data and reports in electronic form.
