By the end of this course delegates will be able to:

• Select the most appropriate production logging services for well diagnosis and reservoir surveillance
• Define injection well profiles using temperature, radioactive tracer, and spinner flow meters
• Measure zonal inflows in production wells using temperature logs
• Locate behind-pipe channels with temperature, tracer, or noise logs
• Apply combinations of flow meters, fluid density, and fluid capacitance logs to measure multiphase flow profiles Interpret cement bond logs and ultrasonic logs to determine cement quality
• Measure flow inside and outside casing with pulsed neutron tools
• Apply specialty tools for flow profiling in horizontal wells
