Characterization of Fracture Length and Formation Resistivity from Array Induction Data

摘要

Measurements made by a multi-array/multi-frequency induction resistivity logging tool in a borehole are used for determining the length of fractures in an earth formation and the resistivity of the unfractured formation when the fractures have a resistive fluid. A look-up table based on modeling of a fracture by a pair of wings is used.
