Objectives and Content

Objectives:
Reservoir geophysics aims to show how geophysical investigations may provide possible types of fluids and volumes of these in rocks that may be several kilometers below the earth's surface. This is important in exploration for hydrocarbons or reservoirs for potential storage of carbon dioxide. Furthermore, this is essential in monitoring and optimized production of reservoirs that are already used for hydrocarbon production or carbon dioxide sequestration. The course covers the wide range of physical principles needed in such mapping, and shows their use in real applications.

At the end of the course, the student shall know the basic principles behind the methods and be able to solve simple relevant exercises, and, furthermore, be able to discuss possible sources of error attached to the results.

Content:
The course has a thematic structure and starts by explaining the various physical properties of rocks and fluids and why they are influencing on geophysical measurements. Particular attention is on seismic. Then a review of quantities describing the reservoir properties of a porous rock is given, followed by various theories for computing the adherent seismic properties. Subsequently, is outlined how seismic properties of a reservoir is depicted in seismic data and seismic attributes. Finally, reservoir conditions are coupled to seismic observables, which defines the main principles of static and dynamic quantitative seismic interpretation.

Learning Outcomes

On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge
The student can explain

  • the seismic properties of a rock
  • the reservoir properties of a rock and how these are affected by various geological processes
  • the most important principles used to calculate the seismic properties of unconsolidated and consolidated rocks
  • the qualitative effects of altered reservoir conditions on seismic properties
  • the most basic steps in seismic analysis and the most important seismic attributes
  • the basics of seismic resolution
  • the various steps in quantitative seismic interpretation

Skills
The student can

  • from petrophysical data compute the adherent elastic and seismic properties
  • compute how the elastic and seismic properties of a multi-mineral and multi-fluid rock may change with altered geometrical distributions of these
  • calculate how mechanical and chemical compaction alter the seismic properties of a rock
  • compute the changes in seismic properties of a rock due changes in pore fluid composition or fluid pressure
  • perform simple Amplitude versus Offset analysis and utilize this in reservoir characterization
  • construct a socalled Rock Physics Template

General competence
The student has

  • acquired knowledge of how rock type and reservoir conditions can be recognized in geophysical data
  • knowledge of how the micro-structure of a rock may influence on its seismic properties on a larger scale
  • knowledge of quantitative seismic analysis on several levels
  • acquired knowledge in quantitative seismic interpretation
  • demonstrated competence in scientific ethics and the ability to work independently and as part of a team
