This hands-on, application-focused 5-day Open and Cased Hole Log Interpretation training program is designed for professionals who regularly work with wireline logs in the oil and gas industry. The course covers the essential techniques and principles behind both open and cased hole logging tools.
Throughout the training, participants will learn about the response of different tools based on their physical principles and how these tools interact with the rock and fluid properties in the subsurface. The course will cover the most commonly used open and cased hole logging technologies, outlining their primary applications and limitations. Participants will also engage in interpreting log data through practical examples and exercises.
Key features of this Energy training course include:
- An overview of the physical principles and applications of open hole tools
- Understanding the limitations of tools in varying borehole environments
- Practical tips and examples for recognizing and addressing common logging issues
- An introduction to petrophysical concepts and fundamental log interpretation techniques
- In-depth exploration of cement evaluation and corrosion detection tools, including their principles and uses
- Analysis of cased hole tools such as resistivity, porosity, and saturation devices
- Practical exercises to apply interpretation methods to real-world scenarios
By the conclusion of this Open and Cased Hole Log Interpretation training course, participants will be able to:
- Comprehend the physical principles behind key open and cased hole logging tools
- Recognize the primary applications and limitations associated with different tool readings
- Conduct a quantitative formation evaluation for simple lithologies
- Effectively utilize and interpret data from both open and cased hole logging tools
This Energy training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented, the sessions will include visual, auditory and kinesthetic elements to cover the three different learning modalities. The daily sessions will be highly interactive and participative. This involves regular discussion of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.
