Since 1991, DOGS has been concerned with the interests of MSc. and PhD. students of the section for Applied Geophysics and Petrophysics of the Faculty of Civil Engineering and Geosciences at the Delft University of Technology. Originally founded in order to find (financial) support for students to attend professional meetings, DOGS also arranges drinks for the students and staff of the section. And DOGS participates in discussions about the curriculum and research of the section in the faculties Curriculum Committee and the section meetings. Another aspect is to establish and maintain contacts with the industry.
