  • Recent advances in well logging and formation evaluation

    Stephen Prensky

    The recent emphasis in logging and formation evaluation has focused on unconventional reservoirs: improved geosteering in ERD and horizontal wells, as well as characterizing and evaluating deepwater laminated turbidites, low-permeability carbonates, fractured tight-gas reservoirs (sandstones and gas shales) and heavy oil/tar sands. This emphasis has produced new and improved technologies that provide additional and more accurate measurements for geosteering (deeper-reading and azimuthal), downhole fluid characterization and analysis, borehole imaging for fracture identification and evaluation, and downhole devices for monitoring fluid movement.
