A world-leader in carbonate reservoir modelling and simulation research.

Our mission is to train next-generation carbonate reservoir scientists and conduct original research that innovates carbonate reservoir modelling and simulation.

Prof. Sebastian Geiger

The Carbonate Reservoirs Group, is world-renowned for its unique combination of applied and fundamental research which aims to provide far-reaching breakthrough technology for the oil and gas extraction industry worldwide.

Carbonate reservoirs hold over 60% of the world's remaining conventional oil reserves but much of the oil contained in them cannot be produced at present. Technical innovation in reservoir modelling and simulation that facilitate an increase in recovery factor and recovery efficiency from carbonate reservoirs will hence be among the most important contributions to the oil and gas industry for the next decade.

The Group currently works the main three different research themes that cover the full range of carbonate reservoir modelling and simulation:

  • International Centre for Carbonate Reservoirs (ICCR)
  • IOR and EOR modelling and simulation in fractured carbonate rocks
  • Next generation reservoir modelling and experimentation

Please visit our Carbonate Reservoir Group website for information on currently active and previous projects.

Areas of expertise

  • Reservoir simulation
  • Reservoir characterisation and modelling
  • Naturally fractured reservoirs
  • Pore-scale modelling
  • X-Ray CT visualisation
  • 3D printing

Research Impact

Multi-scale reservoir modelling for a giant carbonate reservoir

We successfully developed and applied a novel multi-scale reservoir modelling approach that not only led to significantly more robust oil-in place estimates for a highly heterogeneous carbonate reservoir but also a much more reliable dynamic model that could be easily calibrated with dynamic data.

A new pore-scale displacement mechanism in carbonate rocks

Using high-resolution X-Ray micro-computed tomography, we discovered a new pore-scale displacement mechanisms termed “droplet fragmentation” that is inherent to oil-water displacement processes in multi-porosity carbonate rocks.

Universal scaling of spontaneous imbibition

Spontaneous imbibition is one of the key recovery mechanisms in fractured (carbonate) reservoirs. We have been able to find an exact analytical solution to this problem that is applicable to any fluid-rock combination and allows us to quantify large-scale spontaneous imbibition processes from small-scale laboratory experiments.

Further details about these case studies can be found in our Carbonate Reservoir Group website.

Energi Simulation Chair in Reactive Flow Simulation

Energi Simulation is a not-for profit foundation, formerly known as Foundation CMG, which promotes and financially supports R&D and students through research grants and university chair programmes. Energi Simulation supports a major research programme at the Institute of Petroleum Engineering, which is operated by Professor Eric Mackay and by Professor Sebastian Geiger.

This highly interdisciplinary and international research programme tackles major technical challenges related to the sustainable, secure, and efficient production of hydrocarbons. The research involves over 25 PhD students, over 20 MSc students, and several research associates, thanks to significant financial support from Energi Simulation and a wide range of operating and service companies.

Professor Sebastian Geiger at the 2015 SIAM Conference on Mathematical and Computational Issues in the Geosciences

Fractures are ubiquitous in geological formations and often control the successful exploitation of valuable resources such as hydrocarbons, water, and heat. Geoscientists, engineers, and mathematicians have struggled for decades to model and quantify the relevant physical and chemical processes accurately. This presentation will review some of the key challenges and approaches, and introduce new model concepts and numerical techniques that could led to a step-change when simulating heat and mass transfer in fractured geological formations.

EAGE E-Lecture by Professor Patrick Corbett

In this contribution we consider synthetic well test responses generated through numerical simulation of a model derived from an outcrop-based fault/fracture geometry. We consider how the well might connect with the fractures to help understand relationships between the different fracture well test responses.
