Abstract

Utiskivanje ugljikovog dioksida u iscrpljena naftna ležišta je u praksi već dokazano rješenje za povećanje iscrpka preostale nafte u ležištu, a u posljednje vrijeme sve se više razmatra mogućnost trajnog zadržavanja određenog dijela utisnutog CO2 s ciljem smanjenja emisija. U ovom radu opisani su ključni čimbenici koji utječu na učinkovitost navedenih procesa, a provedena je i studija za procjenu potencijala povećanja iscrpka nafte i skladištenja ugljikovog dioksida hrvatskog eksploatacijskog polja Dravske depresije. Za potrebe rada korišteni su program Petrel RE, Eclipse 300 simulator i stvarni 3D model polja. Rezultati računalnih simulacija - različiti WAG omjeri, količine plina, udaljenosti bušotina te koncentracije polimera, razmatrani su za određivanje potencijalno najučinkovitijih strategija povećanja iscrpka i skladištenja CO2.

Abstract (english)

Injection of carbon dioxide into depleted oil reservoirs is already a proven solution for increasing oil recovery, and most recently, the possibility of permanently retaining a portion of the injected CO2 to reduce emissions, has gained traction. The key factors influencing the efficiency of the above mentioned processes are described in this thesis, and a study was also conducted to assess the potential for increasing oil recovery and carbon dioxide storage in the Croatian Drava Depression exploitation field. For the purpose of this Master's Thesis, the Petrel RE program, the Eclipse 300 simulator, and the actual 3D reservoir model were used. Computer simulation results - various WAG ratios, rates of gas and water injection, well distances, and polymer concentrations - were considered to determine the potentially most effective oil recovery and CO2 sequestration strategies.
