EnKF-seir Permalink

Multi-group SEIR model with age classes in an ensemble DA system for predicting spread of the Coronavirus.

History Matching Permalink

Introduction to history matching with ensemble methods (ES, IES and more). Interactive tutorials, also including theory and code. Runnable right in the cloud (no installation). Duration ≈ 3 hours.

Interactive Sequential-decision Geosteering Benchmark

The project allows to compare the decision skills of people and robots for a synthetic multi-target geosteering scenario. The code includes: Server, Client, and Ensemble-Based Decision Support System with uncertainties updated using the EnKF. The Benchmark ...

PerfEst Permalink

Toolbox for simulating tissue blood circulation, and estimating the perfusion.


PET is a toolbox for ensemble based Data-Assimilation developed and maintained by the data-assimilation and optimization group at NORCE Norwegian Research Centre AS.


Leveraging the latest conditional Generative Adversarial Networks (GANs) with spatially adaptive denormalization (SPADE), we establish a novel ensemble-based workflow that effectively captures complex geological patterns. The code performs Bayesian history-...


3D GiG Permalink

3D GiG develops a workflow for automatic, real-time, around-wellbore 3D geological interpretation of LWD logs for optimal well placement decisions.

CSSR Permalink

The main ambitions for the centre are to provide the knowledge required for the Norwegian petroleum industry to transition to zero-emissions production.

DIGIRES Permalink

A Petromaks-2 with industry project that aims to develop the next-generation digital workflows for sub-surface field development and reservoir management.

DigiWells Permalink

SFI DigiWells is a center for research-based innovation funded by the Research Council of Norway and the industrial partners from 2020 to 2028. We are developing new knowledge that will help to drill and position wells in the optimal manner. Our main object...

Distinguish Permalink

Distinguish develops generative-neural-network geomodels that “learn geology”. They unlock next-generation data assimilation and new predictive decision-support AI. We will combine these technologies into the geosteering workflow of the future. It proposes ...

NCS-2030 Permalink

Energy-efficient, multi-purpose utilization of the subsurface into a “Sustainable Subsurface Value Chain” to reach the net-zero-emission goals


In 2020, the petroleum activity on the Norwegian Continental Shelf (NCS) emitted an estimated 12.5 million tons of CO2 equivalents, and NCS 84.7% of the emissions originated from energy production using gas turbines. A substantial part of the energy use is ...
