borehole geology: dip and image interpretation
Course Description
This course covers the basics of dip and image measurement techniques in the borehole environment with an introduction to structural and stratigraphic dip analysis. Tool theory of electrical dipmeter tools and inclinometry systems are explained along with concepts in dip correlation algorithms. Comparisons of electrical, acoustic and LWD image data are presented along with applications and limitations of each technique. In addition to tool and processing theory, an overview of applications is presented so that the participant has a general understanding of interpretation techniques for simple structural and stratigraphic problems. The objective of the course is to provide the student with a complete overview of acquisition and processing systems along with an understanding of interpretation problems and techniques as a basis for the more advanced courses in structural and stratigraphic problem solving.
Audience
Geologists, Geophysicists, Petrophysicists, Engineers and technicians interested with using borehole image and dipmeter data more effectively for integrated studies with basic understanding of subsurface geology.
