... Abstract Geological carbon sequestration through injecting large-scale carbon dioxide (CO 2 ) into the deep saline aquifers represents a long-term storage of CO 2 . In the CO 2 sequestration process, the injected CO 2 is displacing water from the injection point and is expected to remain...

... ABSTRACT Saline aquifers, among other potential CO 2 storage formations, have been proven to offer the highest storage capacity necessary for commercial-scale carbon capture and storage (CCS) projects. They are an ideal target for emission reduction from coal-fired power plants...

... Abstract Deep saline aquifer is deemed as an effective and promising site for carbon sequestration. A geological storage site must be operated safely; however, CO 2 may leak through several pathways, such as fractures, faults and/or improperly plugged wells. This study presents a new...

... estimate the leakage rate. The risk of leakage is presented qualitatively and quantitatively in the form of leaked CO 2 volume to shallow aquifers or to the atmosphere. The approach is used for a representative depleted oil and gas field in southern Louisiana to show an example application of the process...

... Abstract Disposal and long-term sequestration of anthropogenic " greenhouse gases" such as CO 2 is a proposed approach to reducing global warming. Deep, regional-scale aquifers in sedimentary basins are possible sites for sequestration, given their ubiquitous nature. In order for CO 2...

... of CO2 into the underground formation. While injecting CO2 into the formation, residual gas trapping and solubility trapping are the most important trapping mechanisms for CO2 storage in saline aquifers. The lack of information about the geological formation results in uncertainties in specifying...

... Abstract Storage of CO2 into geological formations is a reasonable technical choice for decreasing carbon dioxide emissions to the atmosphere. The dissolution of supercritical CO2 in formation water is one of the main long term trapping mechanisms for CO2 storage into saline aquifers...

... and pressurization. The production of energy from geopressured aquifers has evolved as a separate, independent technology from the sequestration of carbon dioxide in deep, saline aquifers. A gamechanging new idea is described here that combines the two technologies and adds another: dissolution of carbon dioxide...

...). By 1966, nearly all the wells were plugged and abandoned and the Tuscaloosa reservoir was idle and in pressure recovery until Denbury began injection for the EOR project. aquifer upstream oil & gas reservoir characterization cranfield site cranfield shallow aquifer geochemical parameter...

... Partnership on Carbon Sequestration (SWP), a net of ~ 2.9 million tons of CO2 will be injected into the Navajo formation at Gordon Creek, Utah over a period of 4 years, starting in 2013, for permanent sequestration. The Navajo formation is an aquifer that is currently used for disposal of produced water from...

..., the wave velocity will be only function of fractional flow terms, gas saturation, and the slope of fractional flow curve if the compressibility of the rock is negligible compared to that of CO2. Thus, this paper explains how fast a compressible CO2 plume will travel along the aquifers length. In practice...

... sequestration in deep saline aquifer; however, it can also be extended to incorporate more cases. The traditional solution algorithms to this problem are based on discretizing the governing laws on a generic cell and then proceed to the other cells within loops. Therefore, it is expected that, calling...

... sequestration include depleted oil and gas reservoirs, coalbed methane and shale gas reservoirs, and deep aquifers. Though each of these disposal systems has their advantages, deep aquifers (mostly filled with non-potable or brackish waters) have the greatest potential for large CO2 sequestration programs...

... the pressure increase while also limiting the spatial extent of the pressure increase. The impact of brine extraction is investigated using a hypothetical injection domain conditioned by parameters from the Illinois Basin. The domain contains one injection well and encompasses several aquifers connected...

..., the Potomac aquifer, provided the most suitable potential reservoirs for large-scale storage of CO2. In addition to the geologic characterization, a cost analysis was conducted for source-to-sink matching. This was completed in order to determine a lowest cost scenario for transport of CO2 from the producing...
