Query: A Sparse Bayesian Estimation Framework for Conditioning Prior Geologic
  Models to Nonlinear Flow Measurements   We present a Bayesian framework for reconstruction of subsurface hydraulic
properties from nonlinear dynamic flow data by imposing sparsity on the
distribution of the solution coefficients in a compression transform domain.
