Oil and gas fields, produced water, characterizing parameters, salinity, cations, anions, concentration.

Produced water is referred as the largest volume source of waste stream product generated through oil and gas exploration and production. These waters are generated as a result of crude oil and natural gas production, including both onshore and offshore sources. Produced water comes from formation water that naturally trapped under the hydrocarbon layer in oil and gas reservoirs. The traditional method to dispose of produced water involves deep well injection, but this option is becoming more challenging due to high operational cost, limited disposal capacity, and more stringent regulations. Great quantities of produced water (formation water, brine) are associated with the production of oil and gas in oilfields. Therefore, evaluation of produced water characteristics is very important and essential for both environmental and reservoir management. This study has evaluated the physical/chemical properties of formation water in Sarir oilfield, Libya. The study carried out on the quantities of produced water of five gathering centers and the water produced through 2018 and 2019 years, as well as washing water. The evaluation included the analysis of physical/chemical such as pH, specific gravity, salinity, Total Dissolved Solids (TDS), cations and anions constituents. These parameters show a wide variation in the investigated water. The characterizing parameters such as formation volume factor of formation water ( ), density , isothermal compressibility coefficient ( ), coefficient of viscosity ( ) and water resistivity ( ) have been estimated, as well as Stiff diagrams plotting. They show a variable result in the studied waters, and similarity with Stiff diagrams behaviour. The salinity of produced water in year 2018 is less than that of 2019.
