By means of demonstration material, the author reports on the successful application of a shooting technique for seismic reflection operations, which has proved to work satisfactorily in those parts of the North-West German prospective oil area which are unfavourable to reflections. The shooting technique is characterized by uniformly linear shotpoint arrangements which are parallel with the geophone spread and reach from one end of the spread to the opposite. All charges are detonated simultaneously.Technical details of the method are discussed, particularly the problem of the most favourable geophone spreads in continuous profiling as well as the position of the uphole geophone. The difference in quality of reflections obtained by the normal pattern shooting and the linear shotpoint arrangement is demonstrated by seismograms. The special problems involved in the interpretation of the seismic records are referred to.
