Since establishing of E&P in 1952, exploration works have been carried out constantly, firstly throughout Croatia & the neighbouring countries and in the later years worldwide. INA has started with its data processing in 1968 applying digital processing. From 1969 the processing was performed on the TIAC/TIDAR computer having memory capacity of 4K. At the same time the GSI software package was used. The new UNIVAC 1110 computer and Geocom software packages were purchased in 1974. Those tools were used until 1981 when they were replaced by UNIVAC 1170 computers and Digitech software packages. To be in line with fast IT development, INA purchased the IBM computer with 4341 RAID processor and software package manufactured by Western Geophysical in 1984. Then, the new IBM RISC computer and Western Geophysical’s Omega software package were in use from 1994. To extend its processing data capacities INA purchased the new computer manufactured by Silicon Graphics in 1997. The extra memory was added to it in 2001 and 2004. Finally, the Xeon CPU model (HDD – 20 TB, RAM – 88 GB) was purchased in 2007. The Omega software package has remained in use, currently in its improved 2009 version (OMEGA2).
