Seismic inversion is the inverse problem in seismic data processing. Seismic inversion is normally used to recover the medium properties or reflectivity series given the input seismic traces. Nullspace is common in linearized inversion where many vectors could be mapped into the one vector. It is an indication that many models could fit the same data, regardless of the inversion method. Inversion could give odd geometric shapes that are not physical or geological. We will discuss mitigation of nullspace to yield results that are meaningful for interpretation of geologic layers for oil and gas exploration.
