Is gas and oil drilling mostly computerized? 


  


How much do you know about gas and oil drilling?


From locating new reserves to analyzing crude as it's refined, the oil and gas industry utilizes computer technology at every step of the way. Indeed, as proven reserves have dried up and new sources of oil and gas have become harder to find and exploit, computers have taken an increasingly important role in the industry.


That said, humans continue to be an essential part of the process. Though data may be collected and analyzed by a computer, it is a human, ultimately, that interprets the results and makes a decision to drill or move on. Though computers control the speed, force, and depth of a drill, it is a human that monitors and modifies the variables. And, of course, it is a human that makes the dangerous connections between drill pipes as the well pushes deeper.


Indeed, though computers have made drilling for oil and gas a safer and more efficient process, it remains a handson industry.
