LWD / MWD and Stratigraphic Outcomes New achievements include cable and MWD logging, autonomic tuning of NMR techniques, radial acoustic measurements and 3D digital core evaluation. The advances discussed in this article include: LWD / MWD measurements - depth accuracy, new telemetry, pulsed neutron formation evaluation, directional resistivity measurement and LWD measurements; formation testing - a new single Probe manometer and downhole fluid evaluation; Wireline logging - Electrokinetic logging, radial acoustic imaging, open-hole pulse-neutron logging and autotune NMR instruments; Coring and analysis - High Resolution digital imaging and 3D digital petrophysical evaluation; and gas hydrate formation evaluation and data uncertainty analysis.
