As part of the West Coast Regional Carbon Sequestration Partnership (WESTCARB), Advanced Resources International, Inc. evaluated at a preliminary basin level the CO2 storage potential of deep coal seams and saline aquifer sandstones in Alaska. Based on scoping review of petroleum well logs, reservoir data, maps, and geologic reports originally compiled by the Alaska DNR, MMS, USGS, and industry for petroleum exploration purposes, we estimate Alaska has approximately 120 Gt of CO2 storage potential in deep coal seams (Table A) and perhaps 16,700 Gt in saline aquifer sandstones (Table B)
