Abstract
A method includes setting a value of a formation parameter for a subsurface formation and creating an initial three-dimensional (3D) model of the subsurface formation based on the formation parameter. The method also includes applying a constrained transformation to one or more inversion variables of the initial 3D model to create a variable-constrained 3D model of the subsurface formation and applying an unconstrained minimization operation to the variable-constrained 3D model to generate a first transformed 3D model. The method also includes inverting the first transformed 3D model to generate a first inverted 3D model of the subsurface formation.
