Abstract

Kako bi se pokazalo da u nekim situacijama za skladištenje CO2 u duboki slani akvifer nije neophodno postojanje zamke, izrađen je tipski model utiskivanja CO2 u horizontalni, lateralno neograničeni sloj bez zamke. Rađena je analiza osjetljivosti promjenom dubine, te propusnosti, a u rezultatima su promatrane brzine lateralnog širenja. Iz velikog broja simuliranih slučajeva (preko 50), ustanovljene su analitičke ovisnosti – u svakom slučaju je odnos vremena i maksimalnog radijusa širenja od bušotine opisiv logaritamskom funkcijom. Nakon toga je pronađena generalizirana multiparametarska analitička korelacija kojom se za većinu slučajeva dubina i propusnosti, radijus širenja CO2 s vremenom može korelirati unutar pogreške radijusa širenja manje od 7,6 %.

Abstract (english)

In order to show that in some situations the presence of a structural trap is not required for CO2 storage, a generalized model of CO2 injection in deep saline aquifer represented by a horizontal, laterally infinite layer, without structural or stratigraphic trap, was developed. A sensitivity analysis was performed by changing the depth and permeability, analysing the effect the change in the said parameters had on time and radius of lateral spreading of CO2 plume. Analytical dependencies were obtained from a large number of simulated cases (over 50) - in each case the relationship between time and maximum spreading radius from the injection well can be described by a logarithmic function. Subsequently, a generalized analytical multi-parameter correlation was found to describe CO2 plume movement with time within a spread radius with error of less than 7,6 % in different cases of depth and permeability.
