Overview

Production logging refers to a suite of logs that are normally run on completed injection or production wells to evaluate the performance of the well itself or of the reservoir as a whole. Other production logs can evaluate the well completion or look behind pipe to evaluate the formation and its fluids in the near-well vicinity. Production logs are playing an increasing role in modern reservoir management by providing the only means of identifying downhole fluid movements directly. This course will cover fluid flow in pipes (both single and multiphase flow), the theoretical bases of production logging techniques, production log interpretation, and operational considerations. Numerous field examples are used to illustrate the principles of production log interpretation.

Who Should Attend

Petroleum and drilling engineers and managers, reservoir engineers, production engineers/ technologists, petrophysicists, log analysts, and anyone interested in understanding what production logs and cased-hole surveys can tell us

Key Learning Points

• Select the most appropriate production logging services for well diagnosis and reservoir surveillance
• Define injection well profiles using temperature, radioactive tracer, and spinner flowmeters
• Measure zonal inflows in production wells using temperature logs
• Locate behind-pipe channels with temperature, tracer, or noise logs
• Apply combinations of flowmeters, 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
