Take the profile away and drill an 8mm hole at the centre of the mark.
In this application, the characterization of the stratigraphy by vertical seismic profiles in the drilled section, providing seismic images of the to-be-drilled substructures, is obtained using the drill-bit radiated energy.

Students from Arizona State University reported on the exercise: Cory Galvan produced a video about the crew's training, and Connor Radnovich offered a window into the drills in a profile of the team.
The wear rate, surface features, surface profile of the wear product films, composition of the wear product, and variations in drilling fluid temperature under different rotational speeds of drilling pipe were analyzed.
