Introduction to Cased-Hole Data Acquisition and Interpretation

This is a 3-day course which is  an introduction to cased hole data acquisition and interpretations. The course covers three main cased hole topics:

Well integrity: This covers corrosion mechanism and corrosion monitoring, leak detection and cement evaluation

Production logging: This covers production logging in vertical, deviated and horizontal wells and also covers modern technology data acquisition tools to obtain holdups and velocities of the three phases: Water/oil/gas.

Reservoir monitoring: This covers estimations of water and gas saturations behind conductive and non-conductive casings. This includes Pulsed Neutron (PNL) logging and resistivity logging behind conductive and non-conductive casings. .

    Day 1

    Topic: Well Integrity

    • Leak Detection using temperature and noise log profiling and oxygen activation to detect water movements inside and behind single and multiple casings. 
    • Corrosion Mechanism and Corrosion Monitoring. This covers new high technology corrosion monitoring tools and cathodic protection (CP) applications
    • Cement Evaluation: New cement evaluations tools that give detailed circumferential coverage of cementing around the inner casing.

    Day 2

    Topic: Production Logging

    • The various high technology tools that are used to estimate the 3-fluid  phase velocities
    • The various high technology tools that are used to estimate the 3-vertical/deviated/horizontal wells.  hold-ups.
    • Production logging in vertical/deviated/horizontal wells.

    Day 3

    Topic: Reservoir Monitoring

    • Pulsed Neutron Logging (PNL): The physics and applications of PNL to estimate water saturation and gas saturation behind casings. 
    • PNL applications for gravel pack quality control and for log-inject-log applications.
    • Cased Hole resistivity measurement behind conductive casings to obtain formation resistivity measurements. 
  • Topics

    • Well Integrity
    • Production Logging
    • Reservoir Monitoring
  • Audience

    This class is open to all technical domains in the oil and gas industry. No prior cased hole experience is necessary. However, the course will also be beneficial to engineers with cased hole experience as it covers modern high technology tools' physics and operations.
