Abstract
A well logging fluid, and methods of using the same, include a base fluid selected from water, water-based mud, or oil-based mud, and an additive material selected from silica or cork or alike. The fluid has an impedance substantially different from that of the base fluid. Such a modified impedance helps improve the measurement accuracy.
