Welcome to the

Carbonate Reservoir Group

The Carbonate Reservoir Group at the Institute of Petroleum Engineering is world-renowned for its applied and fundamental research on improving the predictability of hydrocarbon recovery from carbonate reservoirs.

Current Projects

International Centre for Carbonate Reservoirs (ICCR)

Sponsors

Petrobras and BG Group

 

Investigators

Sebastian Geiger and Rachel Wood (University of Edinburgh)

 

Research

ICCR is a strategic research alliance between the Institute of Petroleum Engineering at Heriot-Watt University and the School of Geosciences at the University of Edinburgh, with close links to academic institutions in Brazil. Its aim is to combine carbonate reservoir geology with reservoir engineering to understand evolution of porosity, permeability, and multi-phase flow properties in (deforming) carbonates to improve the prediction their 3D distributions and calibrate dynamic models more robustly. ICCR is jointly directed by Prof Sebastian Geiger and Prof Rachel Wood but builds on the extensive experience in reservoir geoscience, engineering, and geophysics at Heriot-Watt University and the University of Edinburgh.

Rapid Reservoir Modelling

Investigators

Sebastian Geiger, Matthew Jackson (Imperial College London), Mario Costa Sousa (University of Calgary), Leonardo Guimaraes (Federal University of Pernambuco)

 

Research

Constructing or refining complex reservoir models at the appraisal, development, or production stage is a challenging, time-consuming task, with a high degree of uncertainty. The lack of an intuitive set of modeling, simulation and visualization tools that support expert interpretation from geophysicists, geologists and reservoir engineers significantly increases the challenge.  A particular limitation is the lack of software that allows conceptual models to be rapidly created, using a simple, intuitive interface, and then interrogated for key reservoir properties and behaviours.  This research project will develop rapid reservoir modeling (RRM) software for prototyping complex reservoir models, by means of novel, interactive, modeling techniques, exploratory visualization, and numerical analysis.  The work is planned over three phases, each of which will deliver a complete RRM workflow, but with increasing breadth in input/output data, techniques for rapid model construction, and sophistication of the numerical analyses available. See the project website for more details.

Porous Media - Processes and Mathematics (PMPM)

Sponsors

EPSRC

 

Investigators

Sebastian Geiger and Gabriel Lord (Department of Mathematics, Heriot-Watt University)

 

Research

PMPM is a UK-wide research network focused on all aspects of porous media flow at the interface between engineering, applied mathematics, applied probability and scientific computing. It provides UK researchers, from both academia and industry, with a platform for novel scientific interactions and fosters the creation of a flexible and active UK research community that can respond to large-scale societal and environmental challenges and specific international calls. PMPM is run jointly by Prof Sebastian Geiger and Prof Gabriel Lord.

MicroWet: Role of Microporosity and Wettability on Fluid Flow in Carbonates

Sponsors

BG Group, Chevron, Dong Energy, Wintershall

 

Investigators

Rink van Dijke, Zeyun Jiang, Ken Sorbie (FAST Group) and Rachel Wood (University of Edinburgh)

 

Research

MicroWet is a joint research project between the Institute of Petroleum Engineering at Heriot-Watt University and the School of Geosciences at the University of Edinburgh. It has the aim to link the distribution of micro-porosity with the distribution of wettability in carbonate rocks and understand the impact on multi-phase flow properties. This project is facilitated by ITF.

Multiscale modeling of CO2 migration and rrapping in fractured Reservoirs with validation by
model comparison and real-site applications

Sponsors

US Department of Energy

 

Investigators

Sebastian Geiger, Florian Doster, Mike Celia (Princeton University), Jens Birkholzer (LBNL)

 

Research

This project will develop new modeling approaches for improving the modeling accuracy of CO2 and brine migration in fractured reservoirs by including interactions of flow in fractures and the rock matrix. We will improve understanding of multi-phase CO2-brine flow in fractured reservoirs by studying the small-scale interactions between fracture and matrix flow using a three-dimensional Discrete Fracture and Matrix modeling approach. We will use this understanding to further develop our Multi-Rate – Dual-Block Dual-Porosity (MR-DBDP) Model into existing reservoir simulators develop a vertically integrated modeling approach for fractured reservoirs. We will then investigate CO2 storage capacity and trapping efficiency in large-scale fractured reservoirs with various sensitivity analyses using the newly developed models.  Finally, we will apply the newly developed models to predict the CO2 migration and trapping at the In Salah CO2 storage site, and to conduct sensitivity analysis of fracture-matrix interactions and compare the simulation results with monitoring data.

Probabilistic and continuum approaches to modelling chemical transport with reactions in geological formations

 

Sponsors

Weizmann Institute of Science

 

Investigators

Sebastian Geiger and Brian Berkowitz (Weizmann Institute of Science)

 

Research

The research project aims to combine probabilistic modeling of reactive transport processes using Continuous Time Random Walks (CTRW) and deterministic modeling of the same processes in high-resolution representations of geological structures to develop a probabilistic quantification of hierarchal flow and reactive transport in heterogeneous geological formations.

Pore-scale reconstruction and simulating flow processes in 3D printed rocks

 

Sponsors

Aramco Services Company

 

Investigators

Sebastian Geiger, Eric Mackay, Rink van Dijke, Zeyun Jiang, and Florian Doster

 

Research

This project aims to apply our in-house pore-network modelling software tools to reconstruct complex pore-network geometries in carbonate rocks. It also aims to use our direct pore-scale simulators to study flow and transport process from laboratory experiments that were carried out in artifical, but geologically realistic, rocks generated using 3D printing.
