Abstract (english)
A preliminary assessment of the capacity of regional geological storage in the western part of the Sava Depression was based on data obtained from several deep exploration wells. The Poljana Sandstones represent a regional deep sandstone body, in most parts saturated with water, with promising underground facilities for the storage of CO₂ in the study area. Poljana Sandstones (member of Kloštar-Ivanić Formation bounded between E-log markers Rνand Z') have favourable petrophysical properties and are situated at reasonable depths. According to previous investigations, at depths greater than 800 meters supercritical conditions of temperature and pressure CO₂ are achieved, which ensures easy and safe injection into storage underground facilities. For the creation of a model in Petrel software, various data was used, including the distribution of CO₂ density, porosity, effective thickness and the relative depth of sandstone. Spatial distribution of porosity was made regarding neutron porosity logs. The most important parameter in the estimate of storage capacity is effective thickness, defined by the interval between E–log markers Rν and Z’. Hence, the effective thickness was used for top and bottom surface of sandstones. Density of CO₂ was created according to their spatial distribution regarding the depth and the temperature. The capacity of CO2 storage was calculated by the volumetric method. The use of a calculated Petrel model can subsequently determine the amount of CO₂ storage in the underground facilities of the study area.
Abstract (croatian)
Preliminarna regionalna procjena kapaciteta geološkoga skladištenja u zapadnome dijelu Savske depresije provedena je na temelju podataka dobivenih iz dubokih istraživačkih bušotina. Kao perspektivan podzemni objekt za skladištenje CO2 na istraživanome području utvrđen je regionalni litostratigrafski član Poljana, u najvećemu dijelu zasićen vodom različite slanosti. Pješčenjaci Poljana (litostratigrafski član formacije Kloštar-Ivanić omeđen EK markerima Rν i Z') kao ležišne stijene povoljnih su petrofizičkih svojstava e zaliježu na odgovarajućim dubinama za skladištenje CO2. Prema prijašnjim istraživanjima, na dubini većoj od 800 metara postižu se superkritični uvjeti temperature i tlaka CO2, čime se osigurava njegovo jednostavno i sigurno utiskivanje u podzemne geološke objekte. Definirani parametri pješčenjaka Poljana (dubina zalijeganja, efektivna debljina, poroznost i gustoća CO2) korišteni su kao ulazni podatci za izradbu modela Petrel. Šupljikavost pješčenjaka Poljana izračunana je prema podatcima dobivenim iz dubokih istraživačkih bušotina u kojima je bila obavljena kompenzirana neutronska karotaža (CNL). Najvažniji parametar u procjeni kapaciteta za geološko skladištenje jest efektivna debljina definirana iz intervala između EK markera Rν i Z'. Gustoća CO2 utvrđena je u skladu s njegovom prostornom distribucijom glede dubine i temperature. Kapacitet skladištenja CO2 izračunan je pomoću volumetrijske metode. Uporaba dobivenoga modela Petrel može odrediti količinu CO2 za skladištenje u podzemne objekte istraživanoga područja. Ovaj model može naći primjenu u prostornome planiranju i usmjeravanju skladištenja ugljičnoga dioksida u odabrani duboki vodonosnik.
