That said, larger drillers like Pioneer Natural Resources (NYSE: PXD) aren't getting hit as hard due to their scale and vertically integrated operations. In the case of Pioneer Natural Resources, the company is only assuming 5% cost inflation in its budget this year instead of the 10% to 15% anticipated by the industry because it was able to lock in low-cost sand supplies, for example. That cost inflation is hitting smaller drillers like Carrizo and Parsley harder because they don't have the scale of companies like Pioneer to push back in other ways.
