Key words: hydraulic fracturing, leak off coefficients, cross-linked gel, linear gel, Carter equation, fracturing fluid filtration, fracturing design.

Article is devoted to methodology for determining leak off coefficients on core samples, allowing you to explore filtering fracturing fluids in the rock and adjust designs fracturing in all major industrial simulators of hydraulic fracturing. Considered constant and dynamic models. The relationships between rock permeability and leak off coefficients are determined. Using the techniques presented may improve the efficiency of the operation hydraulic fracturing.
