Likely the article is correct that there are lots of cost savings to be realized.
Just a few years ago, I worked with my nephew who worked for IBM, IBM had identified the oil sector in general as an under-represented entity on using newer technology for efficiencies.
There is a wave coming that will ensure we retain a strong oil industry as it stubbornly changes as other industries have changed toward these improvements for the better.
Changes will come. Another nephew works for the largest rig company in the US and told me that the newest rigs it is making are capable of being run during drilling operations with only two people.
Remarkable.
