Abstract:
In the world, including Hungary, there are several depleting oil and natural gas fields. In Hungary, there is a mining and a governmental regulation stating that when the depleted hydrocarbon reservoirs get abandoned, the wells drilled on them should also be liquidated. However, the liquidation of the abandoned hydrocarbon fields involve very high expenses for the companies in the hydrocarbon industry.
On the other hand, in the forthcoming decades, the European Union and Hungary should decrease the CO2 and the so-called greenhouse gas emission in order to contribute to the sustainable development and the environmental protection. One of the possibilities to decrease the CO2 emission is the capture and storage of the concentrated carbon dioxide released in geological formations.
The depleted oil and natural gas fields have already proven that they are capable of trapping the fluids for millions of years, thus, the possibility of long-term safe storage of carbon dioxide is the highest in these reservoirs.
It seems to be obvious that the depleting hydrocarbon fields should be used as long-term safe CO2 and greenhouse gas storages instead of their liquidation.
In our presentation we demonstrate an analytic calculation method to estimate the carbon dioxide storage capacity of depleted oil and gas fields. It is a detailed calculation which, apart from the simple volumetric view estimation, takes the current production and depletion state of the oil and gas wells into account as well.
We show the laboratory measurement device which is able to monitor the filtration properties of the supercritical state carbon dioxide at reservoir conditions.
Finally, we present how they can be used to determine the capacity of the carbon dioxide injection well.
