Surface pointing techniques

A method for processing seismic data, comprising:

• analyzing in a processor seismic data as a function of at least four dimensions corresponding to parameters x1, x2, xn and xd,
• defining plural three dimensional volumes based on parameters x1, x2, and xn, wherein each three dimensional volume corresponds to a different value of the parameter xd, wherein each three dimensional volume includes one subset of the seismic data,
• performing data picking propagation in one three dimensional volume on at least one subset of the seismic data which corresponds to a collection of the seismic data sampled in three or two dimensions, in which case the quantity or quantities of other data which correspond to the other dimension or dimensions are fixed values,
• applying a predetermined projection law to at least one of the points highlighted by the data picking in the one three dimensional volume propagation to determine a point in another three dimensional volume which corresponds to the highlighted point in another subset corresponding to a collection of seismic data sampled in the same dimensions, for a different value of the parameter xd, wherein an image of a subsoil is generated.
