May 2012 - knowledge sharing event in Alabama
In May 2012 a knowledge sharing event was held in Alabama, between 10 projects from the USA, Canada and the Network. This event focused on the CO2 monitoring techniques and approaches taken by the different projects. It was organised by The Southeast Regional Carbon Sequestration Partnership (SECARB), the Southern States Energy Board, the Global CCS Institute, Natural Resources Canada, the European CCS Demonstration Project Network and the U.S. Department of Energy. These ranged in scale (from pilot to the commercial large scale injection of CO2), location (comparing onshore and offshore challenges), process (EOR monitoring as opposed to CCS), project maturity (from planning to ongoing injection), risks and opportunities (hundreds of wells to a small number), and focus (research as opposed to commercial). Despite this variety – a number of shared learnings were made.
- Some techniques are becoming ‘standard’, particularly downhole P&T sensors. Others, such as 3D seismic, are proving themselves to be powerful tools, if it can be appropriately used.
- Clear and agreed definitions for monitoring objectives are needed. Characterisation of the local rock/fluid/stress system is important.
- Reservoirs will always cause surprises.
- Appropriate baseline measurements are critical.
- Public engagement is key, especially at an early stage.
Going forwards more work is required on monitoring technologies and techniques. In particular further work is required on costs; needs; interpretation of the data; and triggers - especially for communications with regulators. More details of this event, and links to the presentations hosted on the SECARB site can be found in the Network report, here.
