    • Guide trajectory adjustments to stay within target reservoir zones
    • Recommend casing setting depths and call phase TD and well TD when geologically established
    • Recommend coring points and optimize rate of penetration versus geological real-time acquisition sampling rate compliance
  • Supervise and anticipate services under geoscience perimeter (equipment, personnel, activity, NPT)
    • Manage and ensure quality in mud logging, wireline, LWD, and coring operations
    • Execute acquisition programs and ensure data quality and completeness
    • Oversee sample handling and shipping (gas, cuttings, mud, cores, rotary sidewall cores, fluids samples, etc.)
  • HSE compliance and risk management
