Possibilities of geological CO2 storage in depleted/partially depleted layers of hydrocarbons in north east Slovenia

Mogućnosti geološkog skladištenja CO2 u osiromašenim/delimično osiromašenim slojevima ugljovodonika u severo-istočnoj Sloveniji

Abstract

 The quantities of produced CO2 in industrial processes in the world as well as in Slovenia are increasing yearly. Releasing CO2 into the atmosphere has negative impact on the climate as CO2 is one of the most important greenhouse gases. One possibility of reducing CO2 emissions into the atmosphere is by capturing CO2 in industrial processes, transporting and injecting it into suitable underground geological structure or geological storage. The most appropriate area in Slovenia for geological CO2 storage is in Northeast Slovenia where potentially suitable layers for storing CO2 can be found, namely the depleted or partially depleted oil and gas layers, saline aquifers and coal layers. The depleted or partially depleted layers of oil and gas from the oil and gas layers Petišovci are proposed as test layers for storing CO2 mainly because of extensive geological, geophysical, well and surface infrastructure data and especially because in the process of storing gas, additional large quantities of oil could be produced (EOR).
