Oil industry automation fact of the day

From the Times on the new labor market normal in oil drilling in the US, 

Roughly 163,000 oil jobs were lost nationally from the 2014 peak, or about 30 percent of the total, while oil prices plummeted, at one point by as much as 70 percent. The job losses just in Texas, the most productive oil-producing state, totaled 98,000. Several thousand workers have come back to work in recent months as the price of oil has begun to rise again, but energy experts say that between a third and a half of the workers who lost their jobs are not returning. Many have migrated to construction or even jobs in renewable energy, like wind power... 

Indeed, computers now direct drill bits that were once directed manually. The wireless technology taking hold across the oil patch allows a handful of geoscientists and engineers to monitor the drilling and completion of multiple wells at a time — onshore or miles out to sea — and supervise immediate fixes when something goes wrong, all without leaving their desks. It is a world where rigs walk on their own legs and sensors on wells alert headquarters to a leak or loss of pressure, reducing the need for a technician to check. And despite all the lost workers, United States oil production is galloping upward, to nine million barrels a day from 8.6 million in September. Nationwide, with a bit more than one-third as many rigs operating as in 2014, production is not even down 10 percent from record levels. Some of the best wells here in the Permian Basin that three years ago required an oil price of over $60 a barrel for an operator to break even now need about $35, well below the current price of about $53...

Pioneer Natural Resources, one of the most productive West Texas producers, has slashed the number of days to drill and complete wells so drastically that it has been able to cut costs by 25 percent in wells completed since early 2015. The typical rig that drilled eight to 12 wells a year just a few years ago now drills up to 16. Last year, the company added nearly 240 wells to its Permian Basin inventory without adding new employees.
