Advances in MWD and formation evaluation for 2003 ///

Recent advances in formation evaluation can improve the quality and increase the quantity of formation data, and reduce costs while making operations more efficient. Twenty-nine examples of these advances and related tools discussed here cover: •Wireline logging – Imaging logs, slim HPHT platform, NMR, formation resistivity and electrokinetic logs •Memory logging – Through bit logging •MWD – Telemetry, hostile environment platform, NMR, acoustic, porosity, formation resistivity and caliper logs •Mud logging – GCMS mud hydrocarbon measurement and cuttings permeability •Testing – Wireline formation tests •Coring and analyses – Core logger •General – Service company web sites and NMR fluid properties.
