One option for reducing greenhouse gas emissions GHG is to store carbon dioxide CO2 in deep saline aquifers. Due to their abundance and large capacity, deep saline aquifers make excellent storage sites due to their potential for long-term sequestration. In early 2006, in Salah Gas Krechba field in Algeria became the world's first onshore saline aquifer to begin sequestration. This paper will focus on new insights into surface CO2 monitoring. We will discuss the introduction of geochemical imaging as an emerging surface technique to monitor CO2, recently adopted to investigate and detect tracer gases leaks injected in 2007 from neighboring wells and the cap rock. In the following few pages, we will summarize the geochemical imaging survey process from the implementation design, samples signature measurement to chemical analysis using the sophisticated statistical geo-chemical methods in the final interpretation stage. As a conclusion, the comprehensive analysis of the geochemical data has allowed the Krechba team to investigate the CO2 leakage areas in the field and demonstrates to be an efficient valuable, and accurate method for CO2 monitoring Environmental Engineering carbon capture ISG CO2 Sequestration AGI Full Text Additional Declarations The authors declare potential competing interests as follows: None Cite Share Download PDF Status: Posted Version 1 posted You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
