Numerical Simulation of High Resolution Hybrid Laterolog Tool

In this papar,a new idea about the laterolog resistivity tool,namely the hybrid laterolog resistivity tool is intrduced.The efficient numerical mode-matching method(NMM) combineing with surface integral equation method can match the complex excited condition,and the hybrid laterolog respone is rapidly calculated in a complex media.The result from the numerical stimuluion shows that it has superior vertical resolution and deeper radial measuring depth than regular dual laterolog tool.
