From Site Selection to Characterization: Assessment of Potential Reservoirs in the Lurestan Basin of Iran for Carbon Sequestration

Abstract

The increasing global focus on carbon sequestration underscores the need for comprehensive CO₂ storage atlases, extending beyond Europe and America to other countries that are significant contributors to carbon dioxide emissions. This article addresses this imperative by examining the CO₂ storage potential in the Lurestan area of Iran, with a specific focus on static reservoir modelling and capacity calculation. Our approach involves evaluating potential reservoirs for carbon sequestration using seismic data and well logs followed by site ranking using the Analytic Hierarchy Process (AHP) technique. An in-depth evaluation was then performed on the highest ranking available reservoir. This included construction of a 3D geological model based on integrated well log and seismic data followed by population of the defined reservoir and seal layers with crucial properties based on available well logs. Finally, reservoir storage capacity was estimated using a volumetric approach.
