Course description
Production Logging Wellsite and Downhole Environment
The goal of production logging is to obtain an accurate interpretation of downhole tool measurements of fluid holdups and fluid velocities. Achieving this goal requires an understanding of the equipment used at the wellsite to make these measurements and the equipment used to deploy the tools downhole. It is important to know where the tools are in the well with relation to the well components described in the well schematic. Because most production logging tools only measure what is inside the innermost casing string, it is also necessary to know when the primary cement job may be seriously degrading permitting flow behind pipe. This skill module covers wellsite equipment, gamma ray, casing collar and depth measurements, and acoustic methods to determine cement quality behind pipe.

Training content
You will learn
- The basic components of surface equipment used to log a flowing well
- The basic methods used to flow a well
- The fundamental types of completions used in typical wells and the problems associated with acquiring and interpreting production log data in these types of completions
