“…The Lower Cretaceous Sunniland Formation is a predominantly carbonate unit within the South Florida Basin that forms a potential CO 2 storage reservoir within its petroleum-producing region, known as the Sunniland trend (figs. 2 and 4; Applegate and Pontigo, 1984;Roberts-Ashby and Stewart, 2012). The Sunniland Formation is composed of shallow-water marine deposits that accumulated on a very slowly subsiding platform subjected to cyclic sea level fluctuations, resulting in several carbonateevaporite successions within the formation (Lane, 1994).…”

“…The Sunniland Formation is composed of shallow-water marine deposits that accumulated on a very slowly subsiding platform subjected to cyclic sea level fluctuations, resulting in several carbonateevaporite successions within the formation (Lane, 1994). The Sunniland trend is a slightly arc-like band within the South Florida Basin that is ≈145 mi long and 20 mi wide, where oil production activities have been concentrated to date within the Sunniland Formation (Applegate and Pontigo, 1984;Roberts-Ashby and Stewart, 2012). This region of the Sunniland Formation is also believed to contain the more highly porous intervals of the formation, which are composed of mound-like structures (30-100 ft thick) thought to be shallow-water bioherms, banks, shoals, and barrier beaches made of coarse fossil fragments (predominantly rudistids) and various seafloor debris that are located within the middle to upper parts of the Sunniland Formation (Mitchell-Tapping, 1986;Lane, 1994;; Roberts-Ashby and Stewart, 2012).…”

“…Although porosity within the Sunniland Formation petroleum reservoir is high, it is not limited to the isolated mounds, and the area of porous carbonate within the upper part of the formation is much larger than the area containing the producing oil fields (Beinert, 1976;Applegate and Pontigo, 1984;Mitchell-Tapping, 1987;Lloyd, 1996;Roberts-Ashby and Stewart, 2012). As such, the boundary of the Sunniland Formation SAU is not limited to the producing fields but is instead primarily defined by the area around the Sunniland trend, where the Sunniland Formation is known to be a porous carbonate reservoir rock with proven structural and stratigraphic trapping and a thick regional seal consisting of anhydrites within the Lake Trafford Formation (Applegate and Pontigo, 1984;Mitchell-Tapping, 1986;Lloyd, 1996;Roberts-Ashby and Stewart, 2012). Throughout the extent of the SAU, reservoir-top depths are greater than ≈10,000 ft, as seen in approximately 70 geophysical well logs.…”

“…Throughout the extent of the SAU, reservoir-top depths are greater than ≈10,000 ft, as seen in approximately 70 geophysical well logs. The rocks within the Sunniland Formation SAU deepen and thicken to the southwest (Klopp, 1975;Roberts-Ashby and Stewart, 2012), and on average are 230 to 270 ft thick, with a most likely thickness of 250 ft, as determined from the geophysical well logs.…”

110-140) directs the U.S. Geological Survey (USGS) to conduct a national assessment of potential geologic storage resources for carbon dioxide (CO 2) and to consult with other Federal and State agencies to locate the pertinent geological data needed for the assessment. The geologic sequestration of CO 2 is one possible way to mitigate its effects on climate change. The methodology that is being used by the USGS for the assessment was described by Brennan and others (2010), who revised the methodology by Burruss and others (2009) according to comments from peer reviewers, members of the public, and experts on an external panel. The assessment methodology is non-economic and is intended to be used at regional to sub-basinal scales. The operational unit of the assessment is a storage assessment unit (SAU), composed of a porous storage formation with fluid flow and an overlying fine-grained sealing unit. Assessments are conducted at the SAU level and are aggregated to basinal and regional results. SAUs have a minimum depth of 3,000 feet (ft), which ensures that the CO 2 is in a supercritical state (and thus occupies less pore space than a gas). Standard SAUs have a maximum depth of 13,000 ft below the surface, a depth accessible with average injection pipeline pressures (Burruss and others, 2009; Brennan and others, 2010). Where geologic conditions favor CO 2 storage below 13,000 ft, an additional deep SAU is assessed. The assessments are also constrained by the occurrence of relatively fresh formation water. Specifically, any formation water having a salinity less than 10,000 milligrams per liter (mg/L) total dissolved solids (TDS), regardless of depth, has the potential to be used as a potable water supply (U.S. Environmental Protection Agency, 2009). The U.S. Environmental Protection Agency (2008) has proposed the limit of 10,000 mg/L TDS for injection of CO 2. Therefore, the potential storage resources for CO 2 in formations where formation waters have salinities less than 10,000 mg/L TDS are not assessed (Brennan and others, 2010). This report series contains geologic descriptions of each SAU identified within the assessed basins and focuses on the particular characteristics specified in the methodology that influence the potential CO 2 storage resource. Although assessment results are not contained in these reports, the geologic framework information will be used to calculate a statistical Monte Carlo-based distribution of potential storage space in the various SAUs following Brennan and others (2010). Figures in this report series show SAU boundaries and cell maps of well penetrations through the sealing unit into the top of the storage formation. Wells sharing the same well borehole are treated as a single penetration. Cell maps show the number of penetrating wells within one square mile and are derived from interpretations of incompletely attributed well data (IHS Energy Group, 2011; and other data as available), a digital compilation that is known not to include all drilling. The USGS does not expect to kno...

“…Recently, carbonate saline aquifers have been identified as suitable carbon dioxide sequestration sites due to their high porosity, effective stratigraphic trapping, and global abundance [14,15]. However, in contrast to sandstones, the complex microstructure of carbonates [16] requires a more in-depth investigation before their pore-scale transport can be known.…”

-Carbon sequestration in deep underground saline aquifers holds significant promise for reducing atmospheric carbon dioxide emissions (CO 2 ). However, challenges remain in predicting the long term migration of injected CO 2 . Addressing these challenges requires an understanding of pore-scale transport of CO 2 within existing brine-filled geological reservoirs. Studies on the transport of fluids through geological porous media have predominantly focused on oil-bearing formations such as sandstone. However, few studies have considered pore-scale transport within limestone and other carbonate formations, which are found in potential storage sites. In this work, high-resolution micro-Computed Tomography (microCT) was used to obtain pore-scale structural information of two model carbonates: Indiana Limestone and Pink Dolomite. A modified watershed algorithm was applied to extract pore network from the reconstructed microCT volumetric images of rock samples and compile a list of pore-scale characteristics from the extracted networks. These include statistical distributions of pore size and radius, pore-pore separation, throat radius, and network coordination. Finally, invasion percolation algorithms were applied to determine saturation-pressure curves for the rock samples. The statistical distributions were comparable to literature values for the Indiana Limestone. This served as validation for the network extraction approach for Pink Dolomite, which has not been considered previously. Based on the connectivity and the pore-pore separation, formations such as Pink Dolomite may present suitable storage sites for carbon storage. The pore structural distributions and saturation curves obtained in this study can be used to inform core-and reservoir-scale modeling and experimental studies of sequestration feasibility.Résumé -Caractérisation de la structure de pore de l'Indiana limestone de calcaire et de Pink dolomite provenant des reconstitutions de réseaux de pores -La séquestration du carbone dans les aquifères salins profonds souterrains est très prometteuse pour la réduction des émissions de dioxyde de carbone (CO 2 ) dans l'atmosphère. Cependant, des problèmes demeurent dans la prédiction de la migration à long terme du CO 2 injecté. Relever ces défis nécessite une compréhension du transport de CO 2 à l'échelle du pore dans des réservoirs géologiques existants remplis de saumure. Les études sur le transport des fluides en milieu poreux géologique ont principalement porté sur les formations oléagineuses telles que le grès. Cependant, peu d'études ont
