THE BURNED OVER DISTRICT

To be more accurate, a lot of people in the oil patch have a back up plan if they can. With the price of oil dropping, something many have seen before, they are trying to get ready for the crunch.

“We all have backup plans,” Mr. Allred said with laugh. “You can be sure oil will go up and down, the only question is when.”

Indeed, to residents here in the heart of the oil patch, booms and busts go with the territory.

“This is Midland and it’s just a way of life,” said David Cristiani, owner of a downtown jewelry store, who keeps a graph charting oil prices since the late 1990s on his desk to remind him that the good times don’t last forever. “We are always prepared for slowdowns. We just hunker down. They wrote off the Permian Basin in 1984, but the oil will always be here.”

It’s at times like these that Midland residents recall the wild swings of the 1980s, a decade that began with parties where people drank Dom Pérignon out of their cowboy boots. Rolls-Royce opened a dealership, and the local airport had trouble finding space to park all the private jets. By the end of the decade, the Rolls-Royce dealership was shut and replaced by a tortilla factory, and three banks had failed.

There has been nothing like that kind of excess over the past five years, despite the frenzy of drilling across the Permian Basin, the granddaddy of American oil fields. Set in a forsaken desert where tumbleweed drifts through long-forgotten towns, the region has undergone a renaissance in the last four years, with horizontal drilling and fracking reaching through multiple layers of shales stacked one over the other like a birthday cake.

But since the Permian Basin rig count peaked at around 570 last September, it has fallen to below 490 and local oil executives say the count will probably go down to as low as 300 by April unless prices rebound. The last time the rig count declined as rapidly was in late 2008 and early 2009, when the price of oil fell from over $140 to under $40 a barrel because of the financial crisis.

Unlike traditional oil wells, which cannot be turned on and off so easily, shale production can be cut back quickly, and so the field’s output should slow considerably by the end of the year.

The Dallas Federal Reserve recently estimated that the falling oil prices and other factors will reduce job growth in Texas overall from 3.6 percent in 2014 to as low as 2 percent this year, or a reduction of about 149,000 in jobs created.

And so Rick Perry hands off to Greg Abbott.
