I believe there has been more growth in petrochem related to increased natural gas production than in the increased oil production.
The increase in natural gas has lead to an increase in natural gas liquids like ethane, propane and the like. Several new chemical plants are being built to take advantage of the new supply.

While the oil production growth has plenty of new jobs related to that production, I do not see growth downstream of that. We are basically just replacing imported oil with domestic oil. We are not see much new growth in refining.
