SPE International Conference on CO2 Capture, Storage, and Utilization,
10-12 November 2010,
New Orleans, Louisiana, USA
MOL (Hungarian Oil and Gas Company) in cooperation with ELGI (Hungarian
National Research Institute-) recently have completed a screening study in
order to determine the CO2 storage potential of HC fields operated in Hungary.
Altogether 180 oil or gas reservoirs were involved into the investigation.
Integrated data bases were available for the specialists for determination of
potential volumetric of the fields. To accelerate the screening process
relating to the deep saline aquifers a new methodology was worked out which
based on the compressibility of the formations and the highest applicable
overpressure. The details of this solution will be presented in details. Based
on the conclusions of this study a group of the potential fields were set up
providing an important input to the ongoing feasibility study.
As a second step, a desktop survey of the whole CCS value chain was concluded.
The biggest existing emitters were mapped with their yearly and daily CO2
output and with the operating technological solutions. Third element of the
investigation was the determination of the possible transportation routs of the
captured CO2. This integrated approach seemed to be a solid base to determine
the optimal connections between the target storage fields and the emitters. The
details of the screening process and the target capacities will be summarized
in the paper.
A Consortium (MOL, Matra Power Plant, ELGI) established for preparing a
feasibility study of the most possible CCS project possibility in Hungary,
details will be found in the paper as well, showing the technical solutions of
capture, transport and storage plans with economics issues.
Preliminary economics resulted that a full value chain CCS might be viable only
with at least 50% EU subvention (both CAPEX and OPEX side), and relatively high
and continuously growing CO2 prices (40EUR/t in 2012 growing up to 55 EUR/t in
2020) are the most critical financial issues for the successful project
1. Geological storage of CO2
In many parts of the world carbon dioxide can be found in geological formations
in natural reserves, where it is often trapped between the pore spaces of
sedimentary rock mostly in the same way as oil and natural gas. The available
alternatives for storing carbon dioxide in geological formations are:
• unmineable coal beds
• depleted oil and gas fields
• deep saline aquifers,
MOL launched an R&D project with involvement of ELGI (Eötvös Loránd
Geophysics Institute), which has been running for three years now where the
target was to review all feasible CO2 storage opportunities in Hungary
In 2009 our R&D study presented answers in the following issues:
• Adaptability of research techniques to the Pannonian Basin based on
• Geological and technical risks and risk assessment
• Determining the suitable geological formations and storage capacities
• Availability of enhanced oil and gas recovery techniques (EOR,
• CO2 storage potential of the depleted hydrocarbon reservoirs of
• CO2 storage possibilities and potential in deep saline aquifers in
