CO2 storage potential of sedimentary basins of Slovakia, the Czech Republic, Poland and Baltic States

Abstract

It has been in creas ingly real ised that geo log i cal stor age of CO 2 is a pro spec tive op tion for re duc tion of CO 2 emis sions. The CO 2 geo log i cal stor age po ten tial of sed i men tary bas ins with the ter ri tory of Slovakia, the Czech Re pub lic, Po land and the Bal tic States is here as sessed, and dif fer ent stor age op tions have been con sid ered. The most pro spec tive tech nol ogy is hydro dy namic trap ping in the deep sa line aqui fers. The uti li sa tion of hy dro car bon (HC) fields is con sid ered as a ma ture tech nology; how ever, stor age ca pac i ties are lim ited in the re gion and are mainly re lated to en hanced oil (gas) re cov ery. Pro spec tive res er voirs and traps have been iden ti fied in the Dan ube, Vi enna and East Slovakian Neo gene bas ins, the Neo gene Carpathian Foredeep, the Bo he mian and Fore-Sudetic Up per Pa leo zoic bas ins, the Me so zoic Mid-Pol ish Ba sin and the pericratonic Pa leo zoic Bal tic Ba sin. The to tal stor age ca pac ity of the sed i men tary bas ins is es ti mated to be as much as 10,170 Mt of CO 2 in deep sa line aqui fer struc tures, and 938 Mt CO 2 in the de pleted HC fields. The uti li sa tion of coal seams for CO 2 stor age is re lated to the Up per Silesian Ba sin where CO 2 stor age could be com bined with en hanced re cov ery of coal-bed meth ane.

Experimental modeling of CO2‐fluid‐rock interaction: The evolution of the composition and properties of host rocks in the Baltic Region

“…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 last mentioned geochemical and thermodynamic properties allow the use of the Cambrian Series 3 reservoir for CO 2 geological storage, whereas the geological conditions are most favorable in the uplifted structures in Latvia. Prospective structures are located both onshore and offshore the Baltic area [ Grigelis , ; Sliaupa et al ., ; Shogenova et al ., ; Šliaupa et al ., ]. CO 2 geological storage has also prospects in Lithuanian and West Russian depleted oil fields and in the Swedish part of the Baltic Sea, in the Cambrian saline aquifer (Fallunden Member) covered by Ordovician Alum Shale Formation and Ordovician‐Devonian rocks.…”

The perspectives and barriers for the implementation of CCS in Poland

“…The CO 2 impact on the selected reservoir rocks – in order to determine their suitability for geological sequestration of this gas ‒ was also studied. What is more, the reactions in the water‐rock‐gas system for the purpose of CO 2 sequestration in aquifers were analyzed …”

“…Poland possesses one of largest aquifers for CO 2 storage in Europe. Due to their large capacities, aquifers may allow long‐term storage of carbon dioxide emissions from large emission sources …”

“…These are mostly depleted gas fields as well as several oil fields with different depletion levels. The potential for CO 2 storage in coal seams is small, ranging from 20 million tonnes for possible concessions in the Upper Silesian Coal Basin to 100 million tonnes of carbon dioxide for the entire Upper Silesian Coal Basin – coal seams at depths of 1‒2 km, while the deposits are mostly in highly urbanized areas …”
