Over the last few years the geological sequestration of carbon dioxide has evolved from a theoretical concept to multiple ongoing research efforts and several pilot field-test demonstration and commercial applications. The number and scale of these projects is increasing exponentially as this topic has significant economic and political implications both in the US and globally.
Geologic sequestration deals with the injection of CO2 into subsurface formations. Most of these subsurface target reservoirs contain saline water (brine). As CO2 sequestration targets, these saline reservoirs are associated with significant uncertainties for long term storage. The greatest technical uncertainties are the storage capacity, injectivity and long-term reliable containment of CO2. Other significant issues include those related to competing in-situ resources (oil, gas or other economic minerals in the target formation), permitting, safety, liability, and cost. The uncertainty in these issues can be reduced by prediction (before injection) and verification (after injection) of the fate of CO2 in the subsurface.
The three societies, AAPG, SEG, and SPE, are all focused on subsurface reservoir technologies, and were thus the appropriate groups to combine their expertise in developing new insights in the field of geologic sequestration of CO2.
This was a three-day meeting with single-session oral and poster presentations. The emphasis was on invited speakers, and limited oral presentations. Oral papers were aimed to be “overviews” with most of the detailed papers presented as posters with a format designed to optimize discussion. Keynote talks were held each morning, and posters were presented in the early afternoon, followed by another oral session. Informal “break-out” sessions of smaller groups addressed specific topics in the evenings, with outcomes of each break-out summarized the following morning.
