DE0873 : Production Logging and Reservoir Monitoring

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops.
Production logging are those logs that are performed on production wells to evaluate the performance of the well and to monitor the reservoir. Other production logs can evaluate the well completion or look behind pipe to evaluate the formation and its fluids in the near-well vicinity. In the absence of production logs, the performances of production or injection wells are evaluated on the basis of data obtained from surface measurements, volumes measured in reservoirs, flow rates from separators and pressure measurements at a given down hole point. These data are generally insufficient to determine the flow rate and nature of the fluids produced from or injected into each point in the well.
Production logs are playing an increasing role in modern reservoir management by providing the only means of identifying downhole fluid movements directly. Their main advantage lies in the capacity for determining how and where fluids flow, even outside tubing's or casings under production conditions. Production logs are very often used for diagnosing defects altering the proper functioning of well, i.e. tubing leaks, casing leaks, communications due to channeling as result of improper cementing, low-pressure intervals taking up part of the effluent.
