Introduction

Production logging refers to acquiring a suite of logging measurements in a completed well that is either on injection or production to evaluate the flow performance of the well or the reservoir. Special purpose production logging instruments can evaluate the well completion or look behind the pipe to evaluate the formation and its fluids in the near-well bore vicinity. Production logs are playing an increasing role in modern reservoir management by providing the only means of directly identifying downhole fluid movement.

This course will cover single-phase and multi-phase fluid flow in pipes, the theoretical bases of production logging techniques, production log interpretation, and operational considerations in acquiring production logs. Numerous field examples are used to illustrate the principles of production log interpretation.

Objective

By the end of this course, participants will be able to:

  • Measure zonal inflows in producing wells using temperature measurements.
  • Measure multi-phase flow using temperature, spinner (flowmeter), and fluid holdup measurements.
  • Define injection profiles using temperature, radioactive tracer, and spinner (flowmeter) measurements.
  • Identify flow behind pipe with temperature, radioactive tracer, or noise logs.
  • Interpret cement bond logs and ultrasonic logs to determine cement quality.
  • Measure flow inside and outside casing with pulsed neutron tools.
  • Apply specialty tools (array holdup and spinners and pulsed neutron tools) for flow profiling in high angle/horizontal wells.
  • Confirm the location of some types of completion components using pulsed neutron measurements.
  • Design a logging program using the appropriate production logging services for well diagnosis and reservoir surveillance
Audience

This course is ideal for :

reservoir and production engineers and geologists, petrophysicists, log analysts and others involved in well surveillance, maximizing recovery, identifying production problems, planning workover operations or utilizing production information in reservoir studies
