Induced seismicity due to fluid injection, including hydraulic fracturing, is an increasingly common phenomenon worldwide; yet, the mechanisms by which fracturing causes fault activation remain unclear. Here we show that preexisting fracture networks are instrumental in transferring pressures larger faults on dynamic rupture occurs. Studies of fracturing-induced North America have often used ob...

Over the past decade, there has been a surge in drilling for natural gas and oil in shale rock. Natural gas and oil extraction using high-volume, slickwater hydraulic fracturing from clustered multiwell pads using long, directionally drilled laterals (known by its popular name ‘fracking’), is an unconventional extraction process that is currently the focus of controversy. The process involves t...

Hydraulic fracturing or hydro-frac fluids can impede well production due to the damage caused reservoir formation and fracture face, generated from adverse interactions with rock. Understanding mechanisms of hydraulic fracturing, optimum treatment designs, pumping/pressure profiles is critical for success. However, realize full potential mitigation strategies conductivity during after its occur...

In the past 10–15 years, innovations in hydraulic fracturing and horizontal drilling have fueled a boom in the production of natural gas from geological formations that were previously unprofitable. The rapid deployment of fracking has been accompanied by concerns about negative externalities. In response, a regulatory regime has emerged that requires disclosure of chemical additives, but prese...

The development of hydraulic fracturing ("fracking") is considered the biggest change to the global energy production system in the last half-century. However, several communities have banned fracking because of unresolved concerns about the impact of this process on human health. To evaluate the potential health impacts of fracking, we analyzed records of more than 1.1 million births in Pennsy...

productivity of an oil well is an important parameter in any oil field development. low production rate of the wells, impose more production wells drilling which directly jeopardizes the economical feasibility of the project. oil production rate in some of the wells is very low due to low permeability of the reservoir rock. several practice like hydraulic fracturing and acid fracturing is very ...

The most problematic hydrocarbons in hydraulic fracturing (fracking) wastewaters consist of fused, isolated, bridged, and spiro ring systems, and ring systems have been poorly studied with respect to biodegradation, prompting the testing here of six major ring structural subclasses using a well-characterized bacterium and a silica encapsulation system previously shown to enhance biodegradation....

Lowto ultralow-permeability formations require “special” treatments/stimulation to make them produce economical quantities of hydrocarbon, and at the moment, multistage hydraulic fracturing (MSHF) is the most commonly used stimulation method for enhancing the exploitation of these reservoirs. Recently, the slotdrill (SD) completion technique was proposed as an alternative treatment method in su...

Hydraulic fracturing—the injection of pressurized fluid, often water, to increase recovery of oil or gas—has become increasingly popular in combination with horizontal drilling. Hydraulic fracturing improves production from a well, but requires a significant amount of water to do so and could put pressure on existing water resources, especially in water-stressed areas. To supply water needs, so...
