The Federal Reserve of Dallas also expects positive economic growth in 2015 in Texas.
"The bottom line is it's going to cause growth to slow, but job growth will remain positive," said Keith Phillips, a senior economist with the central bank division in San Antonio.
Ingham, the Amarillo economist, agreed that Texas will likely lodge some growth in 2015 statewide.
But Ingham predicted about a 10% contraction in the Midland-Odessa oil region, where some 8,000 oil workers will lose jobs and all businesses are affected by the sector.
Ingham said oil companies will be cautious in the short run before hiring back staff, even if oil prices recover. That could result in departures from oil towns like Midland.
"You're looking at at least 18 months out into the future before things start to look a little bit better out there," Ingham said. "Who's in a position to ride that out in terms of not having a job and not having income?"
