This course is to summarize the state of the art of production logging technology. It included the example problems to illustrate the use of various theoretical solution, it also listed an overview of conventional well log technology and is general introduction to the latest methods of production logging technology.

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.

Productions logs provide information required for analyzing the behavior of a well interval. This thus makes it possible to answer four fundamental questions:

(a)    What are the producing intervals?
(b)    What fluids do they produce?
(c)    At what flow rates?
(d)    What is the apparent mean permeability of the layers?

By comparison with the true permeability known from cores or log data, the interconnections between each layer and the well are defined. In new wells, an evaluation made with production logs indicates whether the well is producing as forecast or else whether problems exist in the completion or in reservoir properties. The periodic use of production log is also a way of checking the state the reserve and of following progress in depletion. In this way, maximum recovery can be obtained.

The discovery of problems before the beginning of work over operations enables re-completion procedures to be optimized. Repairs can be simplified and made less dangerous for both the well and the reservoir when the problem has been clearly defined

Production logs are thus a reliable way for solving many production problems. 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.

In this course, it has also included example problems to illustrate the use of various theoretical solution. Wherever possible, it has not only discussed practical difficulties that one may encounter while using the theoretical solutions, but it has also listed some of the method that one can used to obtain the desired information. It also included descriptions on field histories wherever they were available.

This course is mainly directed to the practicing professionals who make engineering calculations and decision on production and injection well applications. For managers, the book helps to review the present state of the art. It also outlined some of new method in production log technology that exist today, such as radioactivity log. These gaps in technology will be useful for research engineers and research professionals to determine the areas of future research.
