ERT - Ensemble based Reservoir Tool - is designed for running ensembles of dynamical models such as reservoir models, in order to do sensitivity analysis and data assimilation. ERT supports data assimilation using the Ensemble Smoother (ES), Ensemble Smoother with Multiple Data Assimilation (ES-MDA) and Iterative Ensemble Smoother (IES).

Support for Markov chain Monte Carlo #188

Closed markusdregi closed 3 years ago

markusdregi commented 6 years ago

See discussion regarding #187 . However, the contact surface with the internal storage is smaller. Specifically, observations and simulated data is not necessary.

Do we have any documentation/link/paper/book about this?

markusdregi commented 6 years ago

We do indeed. Among others: https://www.onepetro.org/conference-paper/SPE-113390-MS

We also have some internal reports and one of the authors as our product owner.. But we'll take a go through of these issues one of the next days :+1:

Markov Chain Monte Carlo (MCMC) is a general purpose technique to sample from distribution; there is a large amount of literature available dating back to the Manhatten project. I would strongly reccomend understanding the general concept before looking to petroleum specific implementations.

andreabrambilla commented 6 years ago

I do have a basic understanding of MCMC (was looking into that for ray-tracing a few years back), I meant if we have some documentation about applying it to history matching ;)
