API Frac Sand Standards and Microproppants
Recently, smaller grains of sand are in demand in the oil and gas markets. While fracking processes started with coarser grains of sand, the market is trending toward finer mesh size silica grains. At first, fracking used silica sand with mesh such as 16-30, 20-40, and 30-50. In the years since, however, the markets have […]
