To build on the prior answers, do you have the 'stache and the will to go after some kind of credential? While not necessary, they will be an accelerant. You also should narrow down your target industry, based on some combination of attractiveness to you and availability. What kind of salary range are you shooting for? It will probably be hard to match your current money at the same level of responsibility somewhere else; it is the bust periods (As well as working locations) which drive oil & gas to pay so well.
I also agree you sound like a project manager. And you can get a PMP relatively quickly, particularly if you could take some of your current work to qualify for your work portfolio. Of course, an MBA would be a significant item, and probably up your alley with your academic ability, but it's also a significant time commitment. (And could be a significant cost--if you pick the wrong choices)
Final thought: if your husband's job is also at risk, is relocation an option.? The US population overall has slowed their migration rate considerably over the last two decades, so flexibility in location with a localized imbalance for your new work identity could also be a big plus.
