THE COST ANALYSIS OF THE SEPARATION OF PRODUCED FORMATION WATER FROM THE HYDROCARBON RESERVOIR USING THE EXAMPLE OF THE UPPER MIOCENE SANDSTONE DEPOSITS OF THE SAVA DEPRESSION

Abstract

Formation water is gathered during the working life of the hydrocarbon reservoir alongside the oil and/or gas and it mostly constitutes the recovery's dominant fluid. The produced formation water is separated during the process of dehydration. This thesis deals with the formation water separation costs regarding the fields A, B and C which are located in the western part of the Sava Depression. The dehydration process regarding the field A is executed in three locations, and regarding the fields B and C it is executed in one location. The technological system of formation water separation and the geological characteristics of the above mentioned reservoirs is represented. A statistical analysis regarding the formation water separation costs has been made, the costs have been statistically estimated and a correlation between the costs relevant for the usual formation water separation process has also been made. The purpose of the analysis of the cost of the dehydration process is the optimization of the production system and cost control of the process.
