Hydraulic ,fracturing, is a controlled, high-pressure injection of ,fluid, and proppant into a well to generate fractures in the rock formation containing the oil or gas. After the hydraulic fracture procedure is completed, the injected ,fluid, is allowed to ,flow back, into the well, leaving the proppant in the newly created fractures.

NASA is undertaking a drilling project on the Moon—the first on any planetary body outside the Earth. The mission’s purpose, collecting subsurface soil and ice samples to search for water beneath the lunar surface, is being compared to collecting core samples on Earth and will use technologies, such as a rotary-percussive drill, that have been adapted from those for h…

Unconventional Fracturing Fluids: What Where and Why
Unconventional Fracturing Fluids: What Where and Why

conventional ,fracturing, fluids causes water to be trapped in the near‐ wellbore region, thereby significantly impairing the ability of gas to flow. Formations with sub‐ irreducible water saturation can be stimulated with fluids that minimize the interfacial tension

During oil and natural ,gas production,, so-called “produced water” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic ,fracturing, (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.
