Nowadays, the hydraulic fracturing of a typical Permian well with a 10,000-foot lateral requires about 12,500 tons of frac sand — enough sand to fill more than 500 large sand trucks. That sand needs to be at the ready — delivered, offloaded, stored, and set for blending and use. If it’s not, the well completion and the start of production would be delayed or the hydraulic fracturing process would be shut down after starting — a mortal sin in the shale world. With reliable, seamless access to frac sand at the well site being so critical, E&Ps and their pressure pumpers are understandably doing all they can to optimize their “last-mile” sand logistics. This involves everything from minimizing truck-delivery congestion to maximizing the speed at which sand is transferred from truck to storage, as well as the type of storage used. It’s all much more high-tech than you might think. Today, we conclude our series with a look at the latest in last-mile logistics, which can account for as much as one-third of the total delivered cost of sand.
