Baltic countries are located in the limits of the Baltic sedimentary basin, a 700 km long and 500 km wide synclinal structure. The axis of the syneclise plunges to the southwest. In Poland the Precambrian basement occurs at a depth of 5 km. The Baltic Basin includes the Neoproterozoic Ediacaran (Vendian) at the base and all Phanerozoic systems. Two aquifers, the lower Devonian and Cambrian reservoirs, meet the basic requirements for CO 2 storage. The porosity and permeability of sandstone decrease with depth. The average porosity of Cambrian sandstone at depths of 80-800, 800-1800, and 1800-2300 m is 18.6, 14.2, and 5.5%, respectively. The average permeability is, respectively, 311, 251, and 12 mD. Devonian sandstone has an average porosity of 26% and permeability in the range of 0.5-2 D. Prospective Cambrian structural traps occur only in Latvia. The 16 largest ones have CO 2 storage capacity in the range of 2-74 Mt, with total capacity exceeding 400 Mt. The structural trapping is not an option for Lithuania as the uplifts there are too small. Another option is utilization of CO 2 for enhanced oil recovery (EOR). The estimated total EOR net volume of CO 2 (part of CO 2 remaining in the formation) in Lithuania is 5.6 Mt. Solubility and mineral trapping are a long-term option. The calculated total solubility trapping capacity of the Cambrian reservoir is as high as 11 Gt of CO 2 within the area of the supercritical state of carbon dioxide.

“…The Utsira sandstone formation at the first in the world Sleipner storage site in the North Sea has a storage capacity of approximately 15 Gt [Halland et al, 2011]. More than 30 anticlinal deep geological structures onshore and offshore Latvia and Lithuania, with different sizes and a storage capacity exceeding 2 Mt of CO 2 , have been estimated as prospective for CGS [Sliaupa et al, 2008a;Shogenova et al, 2009aShogenova et al, , 2009bShogenova et al, , 2011aShogenova et al, , 2011bŠliaupa et al, 2013;Shogenov et al, 2013aShogenov et al, , 2013b. Four geological structures, located onshore (South Kandava and Dobele) and offshore Latvia (E6) and Lithuania (E7) and serving as prospective CGS sites in the Baltic Region (Figure 1), were previously described in detail by Shogenov et al [2013aShogenov et al [ , 2013b.…”

The objective of this study was to determine the influence of the possible CO 2 geological storage in the Baltic Region on the composition and properties of host rocks to support more reliable petrophysical and geophysical models of CO 2 plume. The geochemical, mineralogical, and petrophysical evolution of reservoir sandstones of Cambrian Series 3 Deimena Formation and transitional clayey carbonate caprocks of Lower Ordovician Zebre Formation from two offshore structures in Latvia and Lithuania and two onshore structures in Latvia, induced by laboratory-simulated CO 2 geological storage, was studied for the first time in the Baltic Region. The geochemical, mineralogical, and petrophysical parameters were measured in 15 rock samples, before and after the alteration experiment. The diagenetic alterations of reservoir rocks were represented by carbonate cementation in the top of the onshore South Kandava structure, and quartz cementation and compaction, reducing the reservoir quality, in the deepest offshore E7 structure in Lithuania. The shallowest E6 structure offshore Latvia was least affected by diagenetic processes and had the best reservoir quality that was mainly preserved during the experiment. Carbonate cement was represented by calcite and ankerite in the transitional reservoir sandstones of very low initial permeability in the upper part of the South Kandava structure. Its dissolution caused a significant increase in the effective porosity and permeability of sandstones, a decrease in the weight of samples, bulk and matrix density, and P and S wave velocities, demonstrating short-term dissolution processes. Only slight geochemical changes occurred during the experiment in offshore reservoir sandstones. Minor dissolution of carbonate and clay cements, feldspar and some accessory minerals, and possible minor precipitation of pore-filling secondary minerals associated with slight variations in rock properties, demonstrating both short-term and long-term processes, were suggested. As a novelty, this research shows the relationship between diagenetic alterations of the Cambrian Series 3 Deimena Formation reservoir sandstones and their changes caused by the CO 2 injection-like experiment.

“…The volume of the serpentinites in the largest Varena Iron Ore Deposit was estimated as large as 1-2 Gt. Consequently, the sequestration potential is evaluated to be roughly as high as 0.5-1 Gt [18]. This quantity may provide sufficient resources for storing the volume of CO 2 emitted in hundreds of years in Lithuania.…”

Mineral sequestration has a great potential for abating CO 2 emissions, especially at locations where no opportunities for CO 2 geological storage exist. This article focuses on the mineral carbonation of magnesium silicates, that is, serpentinites, which offers an attractive option for CO 2 emission mitigation in Lithuania. Mineral CO 2 carbonation in a staged gas/solid process route is one of the most prospective approaches. The process was conducted in several steps. Firstly, extraction of the magnesium hydroxide from serpentinite via a solid/solid reaction between serpentinite and ammonium sulfate salt at a temperature interval of 500-540 C was carried out. The maximum Mg extraction (53.70 %) was obtained with the mass ratio of reactants of 2 g serpentinite/3 g ammonium sulfate, reaction temperature, and time of 520 C and 20 min, respectively. Secondly, the process of precipitation of Mg(OH) 2 took place. The effect of precipitation of the Fe-containing compounds (first step) and the Mg(OH) 2 (second step) was analyzed. At the pH of 8-10 and 10-12, compounds of Fe and Mg precipitated, respectively. The optimal Fe removal and Mg extraction was achieved at the pH of the $9.5 for the first step and at the pH of $11.50 for the second step. Finally, the carbonation of extracted magnesium hydroxide was accomplished and reached the effectiveness of 65 % after 15 min at 535 C, 51 bar.
