Natural sands must be from high silica (quartz) sandstones or unconsolidated deposits. Frac sands must be more than 99% quartz or silica. Other essential requirements are that particles are well rounded, relatively clean of other materials or impurities and will facilitate the production of fine, medium and coarse grain sands.

12%The fracture gradient is a critical parameter for drilling mud weight design in the energy industry. A new method in fracture gradient prediction is proposed based on analyzing worldwide leak-off test (LOT) data in offshore drilling. Current fracture gradient prediction methods are also reviewed and compared to the proposed method. We analyze more than 200 LOT …

The Fundamentals of Frac Sand Logistics. Sand is critical to North America's onshore oil and gas production. Much of U.S. oil and gas comes from tight, low-permeability shale, sandstone and carbonate rock that must be hydraulically fractured to stimulate fluid flow. Sand is the proppant that keeps fractures open and allows these so-called ...
Fractals, as with all of mathematics, can be full of paradoxes- they can often be a source of creativity, beauty, and surprise- while at the same time they can be a powerful tool for analyzing and communicating about complex ideas. Fractals often start with a simple geometrical object and a rule for changing the object that leads to objects ...
