A comparison of measuring while drilling (MWD) and wire line methods as alternatives for formation evaluation is now pertinent. The recent addition of neutron porosity and formation density logs to the MWD logging sutie has significantly advanced it as a tool for quantitative formation evaluation. Though wire line measurements are far from obsolete, their replacement by MWD is becoming more common, particularly in high-angle holes. This is the second article in a series on MWD.
