Exploration and Production Business Segment is engaged in exploration, development and production of oil and natural gas in Croatia and abroad. More intensive oil and gas exploration and production in Croatia began after World War II. Former INA Naftaplin, today's Exploration and Production Business Segment, which is synonym for numerous oil and gas fields discovery was founded more than 60 years ago, in 1952. Since it was founded it has been involved in many oilfield operations in Croatia and 20 foreign countries, currently in Angola and Egypt.
During more than 60 years of existence 45 oil and 30 gas fields were equipped and put into operation, around 4,500 exploration and development wells with total depth of about seven million meters, about 1,200 producing oil wells with more than 4,000 km of various pipelines and more than 200 production gas wells and oil facilities and installations were built. Until these days, Naftaplin's production was and still is between 50 and 60 percent of total domestic primary energy production.
Activities in Croatia
INA is strongly dedicated to its exploration and production activities in Croatia and is at the moment the only company with the required equipment, experience, knowledge and projects that can speed up exploration activities in Croatia.
We are proud of the results of our work – since 2010. we have drilled 34 wells, discovered three land oil fields and one smaller offshore gas field and confirmed a gas condensate field on the border between Croatia and Hungary. In 2016 we put into production two gas fields in Međimurje and plan on putting a third one in 2017. In the last two years, with its activities and investments in new technologies INA has managed to increase production of Croatian exploitation fields, switching the trend of natural production decline and we are sure this will continue in the coming years because on June 10, 2016 the Company signed the onshore exploration and production sharing agreement (Block Drava-2) with the Croatian Government.
INA has been present in the northern Adriatic since the 1990’s and the production has begun in 1998. Current exploration activities in the northern Adriatic and Aiza Laura Contract areas are performed in cooperation with Italian oil company Eni through joint company INAgip. More than one billion dollars have been invested since the beginning of the project. Also in the northern Adriatic, in cooperation with the Italian company Edison through joint company Edina, gas from gas field Izabela is exploited.
Adriatic platforms HSE
INA is aware of all the potential risks in its business operations, and has a very elaborate system of health, safety and environment integrated into each part of the implementation of its activities. There were no incidents on our platforms, and each platform is equipped with numerous automatic safety control systems, which stop the activities in case of any irregularity. These activities cannot be restarted until the cause has been detected and eliminated.
The safety of people, environmental protection and the protection of the plants represent the company priority, and all activities are continuously monitored and implemented in accordance with the HSE standards.
From the beginning of plant construction, significant attention has been paid to the protection systems in accordance with all the national and international standards and regulations which are used in the oil industry. With regard to the borehole system and the gathering and transportation system, an emergency shutdown system is installed, which is automatically activated upon occurrence of any process disturbance/incident and closing of a well, part of a processing plant or platform as a whole. Furthermore, wastewater collection and treatment systems are installed, and prior to contact with the sea the water is thoroughly cleaned in order to reach the levels below the ones prescribed by national and international legislation.
In accordance with all the previous environmental impact analyses and performed testing, it has been proven that the platform does not have a negative impact on the environment.
