Sažetak
Formation water injection is one of the constituent parts of hydrocarbon production cycle in the secondary exploitation oil recovery phase. The formation water injection system can be divided the into single and central injection system. The formation water injection costs have been described in this paper using the examples of fields A (central injection system) and field B (single injection system). These are located in the western part of the Sava Depression. The reservoir rocks regarding the oil and gas fields A and B are fine to middle grained sands and quartz micaceous sandstones that belong to the geological age of Lower Pontian. The average porosity (intergranular) in the field A is 15– 35% and in field B is 10-31%, depending on the depth and cementation percentage. Regarding the oil and gas fields described in this paper, there has been made a cost comparison and an injection system sensitivity analysis as well as an analysis of a possible injection systems' costs optimization and rationalization.
