Abstract
A method of determining fracture parameters for heterogeneous formations is provided based upon pressure decline measurements from minifrac tests. The inventions provide methods for generating type curves for heterogeneous formations, as well as a leak-off exponent that characterizes specific fracturing fluid/formation systems.
