Overview

This course is designed to introduce the principles of well narratives and various devices and how to calculate the physical properties or parameters of rocks, especially oil reservoir rocks.

Intended learning outcomes

By studying the course, the student will be able to:

1. Learn about the principles of well narratives and various devices and how to interpret curves.

2. Learn about the various recordings and their uses

3. He can know the thickness of the rock formations and determine the quality of the water in the rocks

4. He acquires skills to deal with curves and extract information hidden within them.

5. Predicts the type of geological formation and the dysfunctional fluids within it from the correct interpretation of the narratives.

6. It infer different relationships between the petrophysical properties of rocks and the development of other petrophysical parameters of the rock.

7. Learn about the different ways to calculate the oil reserve and how to calculate it using different narratives.

8. It interprets and analyzes the narratives by explaining the geology and extracting the properties of reservoir rock.
