  It is shown that using Carter leak-off is an oversimplification that leads to
significant errors in the interpretation of DFIT data. Most importantly, this
article reveals that previous methods of estimating minimum in-situ stress
often lead to significant over or underestimates. Based on our modeling and
simulation results, we propose a much more accurate and reliable method to
estimate the minimum in-situ stress and fracture pressure dependent leak-off
rate.
