Hydrocarbon Reserves Replacement· Methods and Expenditures

<div>Results of INA-Naftaplin's activity in replacement of oil and gas reserves are compared to those of western oil companies. The reserve replacement ratio for the 20-year period from 1975- 1994 is approximately 90%, but is averaged only 43% in the last 5 years when exploration results in all domestic area were poor. Exploration and development costs, which have also been analysed, indicate u higher cost per barrel discovered in the last 5-year period. Acquisition or reserves as a method of reserve replacement is still unknown in Croatia, but precisely this method should provide a solution to the current situation.</div><div>Remaining oil reserves are to be found in old fields in their final</div><div>development phase and only selective introduction of new technologies</div><div>and EOR processes, as well as the lowering of production costs,</div><div>can guarantee their rational production. Full introduction of the reserve management concept is a guarantee that such activity will proceed in a manner customary for western oil companies. Results achieved to date on concessions abroad in dicate considerably higher efficiency and lower oil costs, justifying our growing orientation towards exploration of foreign concessions.</div>
