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.
Key activities in 2013
At the end of 2013, INA had 251 million boe proven and probable hydrocarbon reserves with hydrocarbon production 40,2 mboe/day.
Production start-up on Bilogora onshore and Ika B3 offshore gas fields marked year 2013. Within Croatia onshore exploration five wells were drilled, activities on tight gas reservoirs exploration started and Croatia offshore exploration was continued with two wells drilled with 60% success ratio.
In Angola INA participates in development and production activities on three concessions, all located on offshore Block 3 and has non-operating partner status with various percentages of participating interest and production sharing. In Egypt INA holds interests in four development concessions in Western Desert and one exploration concession in Nile Delta of Egypt. INA is the operator of the Sidi Rahman and Rizk Development Leases of the East Yidma Concession, while it has non-operator status in four other concessions (Ras Qattara, West Abu Gharadig, North Bahariya and Disouq).
Because of the complex political situation in Syria, after Force Majeure was announced on February 26th 2012, all activities regarding Hayan and Aphamia Block were suspended until the “force majeure“ circumstances cease to exist.
