KASHAGAN / KAZAKHSTAN Kyrgyzstan ONSHORE / OFFSHORE Uzbekistan

THE GIANT KASHAGAN - KASHAGAN, 80 KM SOUTH-EAST OF , IN THE NORTH CASPIAN SEA, IS THE LARGEST OIL FIELD DISCOVERED OVER THE LAST THIRTY YEARS WORLDWIDE AND EXTENDS OVER A SURFACE AREA OF APPROXIMATELY 75 KM BY 45 KM. ITS DEVELOPMENT REPRESENTS ONE OF THE GREATEST CHALLENGES FACED BY THE INDUSTRY, GIV- EN THE DEEP, HIGH-PRESSURE RESERVOIR, THE HIGH SULFUR CONTENT, THE SHALLOW WATERS THAT FREEZE IN WINTER AND THE MARKED SHIFTS IN TEMPERATURE (FROM -30°C TO +40°C). THE POTENTIAL DAILY AVERAGE PRODUCTION AMOUNTS TO 1.2 MILLION BARRELS, WITH ESTIMATED RESERVES OF 38 BILLION BARRELS. THE KASHAGAN PROJECT CONSISTS OF TWO DEVELOPMENTS: OFFSHORE COMPLEX (ARTIFICIAL ISLANDS IN THE CASPIAN SEA) AND ONSHORE COMPLEX (BOLASHAK ON- SHORE PROCESSING FACILITY).
