# DeepFlow
### History Matching in the Space of Deep Generative Models

[Pytorch](https://pytorch.org) implementation of [DeepFlow: History Matching in the Space of Deep Generative Models](https://arxiv.org/abs/1905.05749)

## Model Architecture

The model architecture consists of two parts: the generative adversarial network (implemented in Pytorch) and the forward solver ([MRST](https://www.sintef.no/projectweb/mrst/)).
The coupling between the two is implemented in ```deepflow.mrst_coupling.PytorchMRSTCoupler``` and defines a fully differentiable computational graph.

## Interpolation between MAP solutions

Interpolation in latent space between three MAP estimates shown in the publication (Figure 9a-b)

## Usage

To perform the inversion using the available pre-trained generator network use ``` run_deepflow.sh ```  
This requires a current version of Matlab or Octave available on the PATH.  
Interpolation is performed by running ```interpolation.py``` using the example bash file ```run_deepflow_interpolation.sh```.

## Trained Models
Pre-trained models are available in the  [checkpoints](checkpoints/) directory.

## Results and Data

A subset of the results is available in this [Google Drive](https://drive.google.com/drive/folders/1xLkLwDxAGVmfz-o2DzImgr8fP0fQNHW4?usp=sharing)  
The full dataset of the computations is multiple terrabyte in size and cannot be shared.  
Computing each run was made reproducible by setting the run-number = seed command-line argumen.  
Computations were performed on Imperial College CX1 supercomputing facilities.
Total duration: 3 days wall-time on 100 servers @ 4-cores each.

## Matlab / Octave Compatibility
The reservoir simulator that solves the two-phase flow problem and provides gradients via the adjoint [MRST](https://www.sintef.no/projectweb/mrst/)
requires a Matlab license to run, but should be fully compatbile with [GNU Octave](https://www.gnu.org/software/octave/)
