Course content

Core analysis: Permeability and porosity. Capillary pressure. Laboratory measurements. Upscaling by use of average valves, Leverett's J-curve and correlations. Relative permeability. Two phase flow.
Well testing: Pressure drawdown and buildup tests for oil and gas wells. Two-rate testing. The average reservoir pressure. Interference testing. Type curves. The pressure derivative.

Learning outcome

Ingress:
The participants shall learn basic theory to determine reservoir properties by well testing and core analysis.

Knowledge:
The students shall understand the influence of reservoir properties on one- and two phase flow in sub-surface reservoirs.

Skills:
The students shall be able to do well test interpretation and conduct measurements in a core lab.

General competense:
The objective of the course is to teach fundamental techniques as an aid for further studies in reservoir engineering and related subjects.

Learning methods and activities

Lectures, exercises and laboratory exercises. The exam can be changed from written to oral at the postponed exams (continuation exam). Lectures are held in English if international master students take the course.

Compulsory assignments

• Exercises

Recommended previous knowledge
