The GeoEnergy Test Bed has received almost £3m of funding 


The GTB is a national facility which supports collaboration between researchers, technology developers and industrial companies. It enables the development and testing of monitoring technologies and improves the understanding of impacts and processes in the shallow subsurface..

What ERA is doing

A partnership involving the  British Geological Survey (BGS), the University of Leicester and the University of Nottingham's Geoenergy Research Centre (GERC), is working on a project to develop monitoring technologies applicable to geo-energy sector industries, including CO2 storage.

Eleven boreholes of differing depths have been drilled at the GTB near Sutton Bonington in Leicestershire. The geology of the site is similar to that of the North Sea, albeit at a much more accessible depth. The boreholes include deep and shallow injection wells which can be used to monitor the motion of gases and liquids through natural pathways in the subsurface after injection. The GTB is also intended to be used for remote sensing technologies and assessment of the effects of gas injection on microbiological activity.

The multi-borehole array test site currently has the following infrastructure:

  • 11 boreholes varying in depth between 21m and 285m
  • On-site containerised laboratory and office facilities
  • 2 data-capture PCs with fibre data links to the main campus network
  • Fully Wi-Fi enabled lab, office and field areas
  • UAV with CO2 and CH4 gas sensor pods for wide area detection of gas leakage
  • Micro Seismic Array
  • Injection capability, water, tracers and gases

The GTB is fully instrumented with surface and down-hole sensors, and thoroughly characterised. Data from these sensors, alongside the physical materials collected to date, offer a dataset against which future measurements can be compared. The GTB has undergone a range of hydrogeological testing, electrical resistivity tomography surveying, and a full depth rock core has also been extracted for analysis.

Research interest areas include:

  • Gas monitoring; migration, attenuation and remediation
  • Geophysical data collection including micro-seismic monitoring
  • Gas emission soil and atmospheric monitoring
  • Next generation quantum gravity sensors
  • Volatile Organic Compounds (VOC) downhole and surface gas monitoring
  • VOC fingerprinting


The GTB has 11 boreholes drilled to depths of between 21m and 285m
