Abandoned theory for matching wells and seismograms

Let us consider theory to construct a map $\bold m$ that fits dense seismic data $\bold s$ and the well data $\bold w$.The first goal $\bold 0 \approx \bold L \bold m - \bold w$says that when we linearly interpolate from the map, we should get the well data. The second goal $\bold 0 \approx \bold A (\bold m - \bold s)$(where $\bold A$ is a roughening operator like $\nabla$ or $\nabla^2$)says that the map $\bold m$ should match the seismic data $\bold s$at high frequencies but need not do so at low frequencies.  
 \begin{displaymath}
\begin{array}
{lll}
 \bold 0 &\approx & \bold L \bold m - \b...
 ...\\  \bold 0 &\approx & \bold A (\bold m - \bold s)
 \end{array}\end{displaymath} (18)

Although ([*]) is the way I originally formulated the well-fitting problem, I abandoned it for several reasons: First, the map had ample pixel resolution compared to other sources of error, so I switched from linear interpolation to binning. Once I was using binning, I had available the simpler empty-bin approaches. These have the further advantage that it is not necessary to experiment with the relative weighting between the two goals in ([*]). A formulation like ([*]) is more likely to be helpful where we need to handle rapidly changing functions where binning is inferior to linear interpolation, perhaps in reflection seismology where high resolution is meaningful.
