Skills and concepts that students must have mastered
How the activity is situated in the course
Content/concepts goals for this activity
- Instructs students to recognize mudstone vs. sandstone lithology using spontaneous potential logs.
- Teaches the concept of resistivity and conductivity and their underlying causes in pore fluids.
- Shows how to recognize briny pore fluids and hydrocarbons using resistivity logs.
- Demonstrates lithostratigraphic correlation using well logs.
- Introduces the concept of oil/water contacts, based on differing density of petroleum and water.
- Tests the concept of horizontal oil/water contacts within the subject oil field.
- Shows students how to calculate elevations of rock units relative to a datum (sea level).
- Illustrates a structural trap, thereby pointing out the trapping nature of most oil fields.
- Points out the necessity of geologists in the petroleum industry and the use of depositional models.
Higher order thinking skills goals for this activity
- Analysis of data, using electric logs to interpret lithology and fluid content.
- Hypothesis formation and testing (oil/water contacts).
