What are the advantages and limitations of different borehole imaging tools?
Borehole imaging tools are devices that capture high-resolution images of the rock formations and fluid contacts around the wellbore. They provide valuable information for formation evaluation, such as lithology, structure, fractures, bedding, porosity, permeability, and fluid saturation. However, not all borehole imaging tools are the same. They differ in their physical principles, operational requirements, data quality, and interpretation methods. In this article, you will learn about the advantages and limitations of four common types of borehole imaging tools: acoustic, electrical, nuclear, and optical.
