Method and tool for determination of fracture geometry in subterranean formations based on in-situ neutron activation analysis

摘要

A method of analyzing the results of a fracturing process, comprising disposing in a formation fracture at least one of a proppant and a fracturing fluid that comprises a radiation susceptible material; irradiating the radiation susceptible 5 material with neutrons during a single logging pass of a logging tool; measuring gamma-radiation emitted from the radiation susceptible material; processing the measured gamma-radiation data in accordance with a Monte Carlo-based simulation model; and determining formation fracture geometry of the fracture.
