文摘

After the completion of hydraulic fracturing, some part of injected fluids mixed with the formation brines - so called flowback brine, migrate back through the well to the surface. Our autoclave experiments were aimed to reproduce and evaluate the chemical composition of the flowback brine derived from CO2-energized fluid fracturing of shale gas of the Baltic province (Poland).Results show the flowback composition is controlled mainly by the interactions between fracturing fluids and original pore water, and to a lesser extent with the reservoir rock.
