If you operate a company that sells a product (particularly a commodity product) you only have two ways of making a profit: Sell the product for more money or cut expenses (or both). For oil drillers, the price of the product sold is pretty much fixed. Some drillers have “hedged” their production, pre-selling future production at a specific price. But many don’t hedge. And hedging contracts typically don’t extend beyond a year. In the case of oil, the world market sets the price, and the price this week is about half of what it was last week. That means most shale oil drillers won’t make a profit–unless they can trim costs. One of the ways drillers are attempting to cut costs is by asking the companies that do the actual drilling and perform services for them (oilfield services companies, or OFS) to cut the rate they charge.
