Abstract: The paper is focuses on the changes in the hydrochemical indicators of the brine waters at the Patos-Marinza oil field due to the production phase. The Patos - Marinza oil field is one of the largest onshore in Albania and one of the biggest in Eastern Europe. Oil reservoir are related with the sandstone formation of Messinian age. The three main oil-bearing formations in the Patos - Marinza oil field from the bottom to the top are Bubullima, Marinza and Driza. Considering that this oil field is characterized by heavy oil the secondary or tertiary recovery methods have been used for oil production. This has led to the changes in the hydrochemical indicators of brine water. Chemical analysis provides data that for the same oil-bearing layers in the Patos - Marinza field there are changes TDS and the chloride value.
