Advances in MWD and formation evaluation for 2004 ///

The latest advances in formation evaluation, especially data acquisition while drilling, are improving quality and increasing the quantity of formation data, while reducing costs and making operations more efficient. Some of those advances discussed here include: •General – Historical well log interpretation charts, new rock catalog and drilling operations center •Wireline logging – Triaxial induction, NMR, imaging, cased hole evaluation, new logging platform and wireline tool jars •MWD/LWD – NMR steering and formation resistivity •Mud logging – Wellsite mud gas isotope analysis and cuttings NMR •Testing – LWD formation pressure measurements •Coring and Analyses – Logging while coring, pore structure imaging and outcrop permeability.
