Impressed by the homework done by a non OG related personnel.

Just for DNEX part, i am not so sure are they a drilling rig company (not really familiar with this company), coz from their website they are offering "Directional Drilling/Measurement While Drilling/Logging While Drilling Equipment and Services" which is actually different from drilling rig.

And for perforation part, not all the wells are completed that way. There's various way of doing it (open hole, screen, gravel pack etc). Perforation is just one of the many way and highly depends on the each well's situation.

Anyway, still very good job and good article. and hope to see more from you.
