| Zusammenfassung: | A method for identifying fractures from measurements made by a multi-axial electromagnetic induction tool in a wellbore traversing subsurface formations includes determining a value of a fracture orientation indicator from in line components of the multi-axial electromagnetic inducion measurements mode transverse to a tool axis, and parallel to the tool axis. The tool axis is sub-stantially parallel to a bedding plane of the subsurface formations. A value of a vertical fracture indicator is determined using the in line components of the multi-axial electromagnetic induction measurements made transverse to the tool axis, and parallel to the tool axis. |
