Print this pageAbstract: Seismic Experiments, Clinkers Area, Wyoming
Pierre Benichou
Recent exploration in the Powder River basin has shown an area of poor seismic data due to "clinker beds" or oxidized coal beds. To compare different sources (dynamite, primacord, and 
vibroseis
), and to optimize the seismic parameters, two sets of experiments were run: E1 on regular coal beds, west of Sheridan, Wyoming, and E2 on clinker beds, east of Sheridan.
The conclusion is that coal beds do not act as a screen to the seismic energy, however, the clinker beds act as filters, screening high-frequency signals.
