Detection of Inconsistent Coupling in Point-Receiver Land Seismic Data

B006 Z-99 Detection of inconsistent coupling in pointreceiver land seismic data Abstract 1 The digitization of the signals recorded by individual geophones in onshore seismic acquisition gives rise to the opportunity to address a phenomenon well known but impossible to effectively tackle using geophone arrays: inconsistent coupling conditions. We present a method for addressing this long-standing problem and apply it to the data acquired during a field experiment with controlled coupling conditions. Introduction It has been recognized for some time that the motion of a geophone case resting on the earth’s surface is not the same as the motion of
