Learning outcomes
Knowledge
The student will acquire a basic knowledge of the most common geophysical well logs with also a limited interpretation experience, and a significant knowledge of seismic reflection, from acquisition to processing. In particular he/she will be aware of its potential and limitations and, given the appropriate sw, he/she will be able to perform a basic processing sequence.
Assessment criteria of knowledge
During the oral exam the student must be able to demonstrate his/her knowledge of the course material and particularly to be able to discuss problems that are presented.

Methods:

  • Final oral exam

Further information:
The student has the option to split the evaluation into two separate examinations: one concerning the first part on well logs and the other on seismic reflection.

Teaching methods

Delivery: face to face

Learning activities:

  • attending lectures
  • participation in seminar
  • individual study

Attendance: Advised

Teaching methods:

  • Lectures
  • Seminar
