Level : Proficiency

Course Content

  • MUD LOGGING

      • Tasks of various professionals at the drilling site.
      • Main documents carried out.
      • Mechanical parameters (WOH, WOB, RPM, Torque, ROP) & hydraulic parameters (SPP, Flows, Pits and mud characteristics). Physical principles of sensors used on well site.
      • Cuttings (sampling, cleaning & analysis).
      • Detection & evaluation of oil & gas shows while drilling.
      • Carry out a section of geological log.
      • Case studies.
  • CORING OPERATIONS

      • Data collected with coring.
      • Conventional coring operation.
      • Cores bits and drilling strings for coring operations.
      • Advanced coring technics: turbo-coring, soft formations coring, gel coring.
      • Oriented coring system.
      • Side wall coring.
      • Storage and handling process for cores during surface recovery: cores cutting, preliminary well site analysis, storaging of cores.
  • WELL LOGGING & LOGGING WHILE DRILLING

      • Definition of basic concepts used in log interpretation.
      • Wireline logging:
      • Well site setup and log records operation.
      • Main logging tools and applications (caliper, GR, SP, resistivity, nuclear, acoustic).
      • Quick-look interpretation: reservoir identification and characterization (lithology, porosity, fluid types, saturation).
      • Case study.
      • Logging while drilling:
      • Main LWD sensors and measurements (directional, resistivity, nuclear, acoustic, pressure…).
      • Applications for directional drilling, geosteering, formation evaluation, predictive pressure.
      • Pressure measurement concepts.
      • Different technics for sampling with wireline and LWD tools.
      • Prevention actions to handle sampling operations.
  • KNOWLEDGE ASSESSMENT

Learning Objectives
