Geophysics in drilling

• Presentation of the methods for carrying out a deep borehole, taking into account both the technological aspects of drilling and the control of mud and chips ("mud logging").
• Presentation of geophysical methods in drilling or "deferred logging" (electrical, nuclear, acoustic and seismic methods as well as the techniques developed for in-situ temperature, pressure or permeability measurements).
• Use of these methods for petroleum and environmental applications.

- Knowledge of drilling methods.
- Mastery of the physical principle of geophysical drilling methods.
- Introduction to reading and interpreting real data.

- Knowledge of sedimentary and structural geology
- Knowledge of surface geophysics
- Knowledge of petrophysics

Full continuous assessment.

- Presentation of methods for drilling at great depths, taking into account both the technological aspects of drilling and the control of mud and chips ("mud logging").
- Presentation of borehole geophysical methods or "deferred logging":
1) Description of the environment in terms of lithology, porosity and fluid content
- Electrical methods
- Nuclear methods (natural and induced)
- Sonic method
2) Electrical and acoustic wall imaging: estimation of wall deformations (fractures, breakout)
3) In-well seismic
- Illustration of the use of these methods for petroleum and environmental applications.
