Statoil Proposal on detecting micro fractures in organic-rich shales

Nicolas Espinoza

Source rocks can host vast amounts of oil and gas. However, these hydrocarbons are usually highly dispersed in complex and heterogenous formations. Dispersedness and heterogeneity require significant formation evaluation pre-studies and reservoir stimulation actions to maximize the net energy return and the recovery ratio.

Some types of heterogeneity are in fact advantageous, such as natural fractures. Natural fractures create high permeability paths and facilitate reservoir depletion. This project aims at detecting the presence of millimeter and sub-milimeter natural fractures with enhanced well logging techniques.
