The oil business has always been boom and bust or highly cyclical. With prices currently fairly low for crude per barrel. ($69 per barrel) many producers are close to the break even point. So if oil declines from more production, some will stop producing at least until prices come back. I have heard that some already are cutting back on exploration.
IEEFA brief: Oil majors’ shrinking capital expenditures (capex) signal ongoing decline of sector
Making matters worse is if the world has weaker demand from a recession. Sure oil companies like less regulation and more leases for oil drilling, but ultimately it brings intense competition and some companies will cut back some operations or even go out of business. The key to success is the same as any business, you have to be a supplier that has the lowest cost. Here is a break down of three oil fields in Texas and their break even prices.
