Significant event to be reported:

National Agency for Mineral Resources has endorsed the Development Plan for the Domino and Pelican South commercial natural gas fields in the Neptun Deep offshore block

OMV Petrom SA announces that the National Agency for Mineral Resources has today endorsed the Development Plan for the Domino and Pelican South natural gas commercial fields, as it was submitted by OMV Petrom, together with its partner Romgaz (through its subsidiary Romgaz Black Sea Limited).

Consequently, the Neptun Deep project enters the development phase, which includes the execution of drilling activities and construction of the infrastructure necessary for the extraction of natural gas, with the first production estimated for 2027.

OMV Petrom is the operator of the project, with a 50% participating interest. The infrastructure required for the development of the Domino and Pelican South offshore natural gas commercial fields includes ten wells, three subsea production systems and associated flow lines, one offshore platform, the main natural gas pipeline to a natural gas metering station near Tuzla. The platform generates its own energy, operating at the highest standards of safety and environmental protection. The offshore platform, wells and the fields will be operated remotely, through a digital twin. This allows for process optimization and will contribute to the improvement of our environmental performance, by making energy consumption more efficient and minimizing emissions.
