This approach takes advantage of two different model refinement methods (optimal-update and design sensitivity) and two different model size matching methods (model reduction and eigenvector expansion).
This is significant considering that the top CASP8 servers use a combination of multiple structure prediction techniques including consensus method, multiple-template modeling, template-free modeling and model refinement while our method is a classical single-template-based threading method without any post-threading refinement.

Details of the methods used for Phasing and Model Refinement are described in Supplementary methods.
The local model was run independently from the regional model using time-varying specified heads for the lateral boundaries that were previously computed by a coupled regional-local model simulation using the local grid refinement method of MODFLOW-LGR2 (Mehl and Hill 2013).
We also present the dual-porosity dual-permeability model coupled with local grid refinement method to distinguish the impacts of natural fractures and hydraulic fractures on shale gas production.
In addition, we are also investigating ways of implementing automatic post MR model refinement to provide an automatic method of validation.
The obvious way to improve model accuracy would be to either greatly reduce the size of the model core or to create a refinement method that corrects local structural differences such as helix kinks.
In addition, dual-porosity dual-permeability models coupled with local grid refinement method are used to distinguish the impacts of natural fractures and hydraulic fractures on shale gas production with the comparison of vertical well, fractured vertical well, horizontal well, and multistage fractured horizontal well production.
