Description

 

Seismic Imaging: We introduce the concept of seismic imaging in the framework of wavefield extrapolation and the imaging condition. We look at the various migration methods including Kirchhoff, phase-shift migration, Downward continuation methods, reverse time migration and others. We look at the impact of velocity and the role of imaging in estimating the velocity model.

Well Logging: We provide a practical understanding of the principles and interpretation of geophysical well logs in research applications. We will focus on the fundamentals of well logging methods, including electrical, nuclear, acoustic and other measurements.

Petroleum Engineering postgraduate program of the Technical University of Crete is a one-year, full-time program, designed to provide students with a scientific background in hydrocarbon exploration and skills in the practical aspects of petroleum engineering. The program begins in October, and leads to a Master of Science (MSc) degree. The program is run by the School of Mineral Resources Engineering.
