Petrophysics While Drilling

Lithology, porosity, saturation, and permeability

Schlumberger LWD services enable quantitative reservoir evaluation with measurements of petrophysical properties while drilling. A wide range of measurements including gamma ray, resistivity, density, neutron porosity, spectroscopy, sigma, magnetic resonance, and acoustic slownesses can be acquired and transmitted while drilling to facilitate timely, informed decisions in addition to sophisticated formation evaluation.
