Like other European energy companies, OMV, which until the Ukraine war depended heavily on Russian oil and gas, is striving to diversify its supplies.
"For us, it is important that we diversify the gas supply for Austria and this is a building block."
High energy prices meant OMV (OMVV.VI), in which the Austrian state holds 31.5%, nearly doubled its core profit in the third quarter.
For some years, OMV has been shifting its growth focus towards high-quality plastics such as polyethylene, polypropylene and PVC, from oil and gas.
Mubadala, which also holds 24.9% in OMV, agreed to sell a remaining 25% stake in Borealis to ADNOC in April.
