Mar 2022: Energean is involved in the FEED for development of the Irena gas field, 5 kms north of the Izabela field. If the development goes ahead, first gas could be in Q4 2024.


Jan 2021: LNG Hrvatska announced the Croatia’s 1st LNG import facility, on the island of Krk in the Adriatic Sea, started operations on January 1. The cargo originated from the Cove Point LNG facility in Maryland, USA. Krk will have a capacity to send 2.6 bcm per year of gas into the national grid.


May 2020: The Croatian LNG terminal is under construction on the island of Krk, designed to transport up to 2.6 bcm of gas into the Croatian national transmission network as of 2021. BH Gas has also completed the preliminary design for the 160-km long Southern Interconnection project connecting the gas networks of Croatia and Bosnia and Herzegovina.


No significant news in 2019.


Nov 2018: A 2nd onshore license round offering 7 blocks in the Pannonian basin has been launched. Total acreage available is 14,272 sq kms with blocks ranging in size from 1,361 to 2,634 sq kms. The exploration period is 5 years. At the 1st License Round in 2014, 6 onshore  blocks were offered, in Drava, Sava and Eastern Slavonia.

Jun 2018: Eni and INA are in talks to develop a gas interconnector between Italy and Croatia increasing the integration, security of supply, competitiveness, and sustainability of the Croatian market and consolidate Italy’s position as a gas hub. The infrastructure will also be able to operate reverse flows.

Jun 2018: Eni and INA have signed an agreement to enable INA to acquire 100% of Eni Croatia, that currently produces around 2,500 bbls of oil equivalent per day. Supply of natural gas from Croatia will be secured by a commercial agreement ensuring gas produced from the Marica exploitation area continues to be transported to Italy. Eni has now exited the upstream sector in Croatia.


Jan 2017: Croatia has stepped up plans to buy out MOL's 49% stake in INA. Croatia (45%) has been at odds with MOL over management rights and investment policy.


Jul 2016: MOL announced that INA has started test production in two gas fields, Vuckovec and Zebanec, in the Medimurje project. A third field, Vukanovec, is expected to be added in early 2017. Five production wells were drilled to extract around 1 bcm of gas by 2024.

Jun 2016: Croatia awarded four onshore exploration blocks to Vermilion and one block to INA in June 2015 and has now signed the contracts. The exploration period will last 5 years. Another concession was awarded to Oando and that contract is due soon. Another round of tenders for onshore oil and gas exploration is planned but there are no plans for new exploration in the Adriatic Sea.

Apr 2016: Croatia's Hydrocarbon Agency (CHA) said the exploitation of gas and oil reserves in the country is being delayed until the new government prepares everything for the signing of contracts. The former government launched the first offshore tender in April 2014 when companies were offered 29 blocks and a second onshore tender in July 2014. The onshore awards are to go ahead as planned.

Apr 2016: ENI (operator) and Rockhopper will sign a PSA for offshore block 9. The concession is in shallow waters in the Northern Adriatic gas province and contains the Ksenija discovery. Seismic will be acquired during the first 3-year phase, followed by a well in the optional second phase.


Jul 2015: Marathon Oil and OMV have given up on their plans for exploration in the Adriatic Sea, giving up 7 recently awarded blocks. The reason behind the decision was reported to be a border issue with Montenegro although the decline in oil price was probably an issue.

Jun 2015: Three companies will share 6 licences to explore for oil and gas in the northern Drava river basin and in the east of the country. The government will award 4 licences to Vermilion, 1 to INA and 1 to Oando.

Feb 2015: Seven bids were received in the tender for onshore exploration areas in the northern Drava river basin and the east of the country. It hopes to add further areas in northern and central Croatia, particularly in the Dinarides central mountain range, later in the year.

Jan 2015: The Government has granted 10 exploration licences in the Adriatic in the first licence round with bids  received for 15 areas. Marathon and OMV were granted 7 exploration blocks - North Adriatic 8, Central Adriatic 10, 11, 22 and 23, and South Adriatic 27 and 28. ENI and Rockhopper were granted Central Adriatic 9. INA was granted South Adriatic 25 and 26.


Oct 2014: Croatia has received six bids for 15 offshore blocks. The tender comprised 29 blocks; 8 in the north and 21 in the central and southern Adriatic Sea. The government plans to sign agreements by spring 2015. The country is also running a tender for onshore blocks.

Jul 2014: Croatia is to launch its  first onshore licensing round after its first offshore round opened in April. Six blocks will be put on offer in the Drava, East Slavonia and Sava regions. Each will be between 2,100 and 2,600 sq kms in the Pannonian basin.

Jul 2014: INA (30%) and Edison (70%) have started production from the Izabela field. The field is in the northern part of Adriatic Sea, 57 kms off Pula and has 1.4 bcm of gas reserves and will produce 0.28 bcm each year. Production comes from 2 unmanned platforms (North and South) in a water depth of 37m with gas processing and compression at the Ivana A and K platforms connected to Izabela by a 26 km pipeline.

Feb 2014: Croatia intends to offer 29 exploration blocks in the Adriatic Sea in its licensing round in April. Of these, 8 will be in the northern Adriatic and 21 in the central and southern Adriatic with the exploration areas ranging in size from  1000  to 1600 sq kms and water depths from 100 m in the northern part  to 1000m in the south.

Jan 2014: The economy ministry says that it will open a data room in February 2014 that companies interested in exploration of the Adriatic Sea can access. This is to expedite the award of tenders which will be published for areas in the central and southern Adriatic Sea in the second quarter of 2014.

Jan 2014: Spectrum has completed its multi-Client 2D seismic survey covering 15,000 kms which represents the majority of offshore Croatia using a 5 x 5 km grid and connecting to Spectrum’s Italian Adriatic data. Final processed products will be available by April 2014 as a precursor to the licensing round that Croatia plans to hold in 2014.

Jan 2014: INA signed contracts worth US$43mm with engineering firms to start gas production from 3 fields in the north of the country as part of the Medjimurje project. Reserves are estimated at 1 bcm.


Dec 2013: INA reports that EOR operations are planned in wells in 3 fields in the Pannonian Basin before the end of 2013; Molve, Zutica Duboka and Zebanec.

Sep 2013: Croatia plans to publish tenders for its licensing round in the second quarter of 2014 with first concessions awarded in 2015. Spectrum will shoot 12,000 kms of 2D seismic in the Adriatic Sea for the round with the results available in early 2014.

Aug 2013: Croatia has selected Spectrum to carry out a 15,000 km 2D seismic survey in the northern and southern parts of the Adriatic Sea ahead of a licensing round in 2014. The survey will connect data covering the Italian Adriatic. Significant gas fields produce in the northern Adriatic and oil fields exist in the south in Italian waters.

May 2013: The Croatian government is planning new legislation to improve the obtaining of concessions and legal security and flexibility in oil and gas investment projects. It will offer a single procedure for issuing a permit, signing a contract and obtaining a concession as well as the establishment of a hydrocarbons agency by the Economy Ministry.


Sep 2012: Industrija Nafte (INA) has made an onshore oil discovery with its exploration well Deletovci Zapad. INA, a subsidiary of Hungarian MOL, said that tests indicate approximately 600 bbls of oil per day. The well was a continuation of positive results, including discoveries at Selec-1 in 2011 and Hrastilnica-3 in 2012, in the Pannonian basin.
