Abstract: A method and sensor device for recording seismic data. The sensor device includes a top section and a bottom section removably attached to the top section through a connecting plug. The bottom section holds a coupling material that is released into ground upon the bottom section impacting the ground.

Abstract: A method for processing seismic data, characterized in that with a view to analyzing them as a function of at least four dimensions. Picking and/or picking propagation is carried out on at least one subset of data which corresponds to a collection of data sampled in three or two dimensions. The quantity or quantities which correspond to the other dimension or dimensions are fixed values. In applying a given projection law to at least one of the points highlighted by the picking and/or picking propagation to determine a point that corresponds to it in another subset corresponding to a collection of data sampled in the same dimensions for a different value of at least one quantity that corresponds to at least one other dimension.

Abstract: The invention concerns a method for processing seismic data. The invention is characterised in that so as to prepare them for analysis based on at least four dimensions, it consists in: using a pointing and/or a pointing propagation on at least a subset of said data corresponding to a collection of data sampled in three or two dimensions, the quantity/quantities corresponding to the other dimension(s) being then fixed values, then in applying to at least one of the points highlighted by this pointing and/or pointing propagation a given projection law so as to determine a point which corresponds thereto in another subset corresponding to a collection of data sampled in the same dimensions, for a different value of at least one quantity corresponding to at least another dimension.
