Sentences with phrase «through fractures in the rock»

Hydrogen gas produced by reactions in the repository could build up pressure that leads to radioactive gases escaping through fractures in the rock.

Not exact matches

The area underlying Pennsylvania, Ohio and West Virginia is the epicenter of a boom in American natural gas produced through hydraulic fracturing, the process of injecting water, minerals and chemicals underground to free oil and gas from rock formations.

Texas oilman George Mitchell didn't invent hydraulic fracturing, but, through much trial and error in the»80s and»90s, he demonstrated the technique was a commercially viable way of squeezing oil from otherwise impermeable rock.

My attention might be fractured during the day but we do find our moments — thanks to nursing, babywearing, or if we go visit my parents and then my mother sits and holds her for her late afternoon nap, patting her bum in the rhythm that has been passed down through the ages while rocking slowly.

«This study showed that intrinsic colloids formed by interactions between soluble Cerium (Ce) and carbonates significantly increase the mobility of Ce injected into a carbonate rock fracture,» explains BGU Zuckerberg Institute for Water Research Director Prof. Noam Weisbrod, Ph.D. «The formation of intrinsic colloids, if not accounted for, could result in the under prediction of radionuclide migration through fractures in fine - grained carbonate bedrock, such as chalk.»

That's particularly true for those inside volcanic craters and impact areas, where water moving through fractured rocks could bring iron to the surface, says Jack Szostak, a Harvard University molecular biologist who also took part in the work.

Seawater circulating through fractured volcanic rock above sources of heat participates in chemical exchanges with the rock.

In Northern California, AltaRock Energy hopes to become the first of many developments to produce geothermal energy by fracturing rock at the bottom of a deep hole and then circulating water through the cracks to generate steam.

The new pumps are critical for «enhanced geothermal systems,» in which energy is produced by fracturing dry rock at the bottom of a deep hole and then circulating water through the cracks to generate steam.

Furthermore, scientists estimated the amount of helium released by the rocks through rock fracture experiments in the laboratory using rock samples that were collected from around the earthquake region.

When hydraulic fracturing or «fracking» to access unconventional oil and gas reserves was a hot topic in the fossil fuel industry, Ryerson was tapped to lead a team to develop GEOS — a dynamic computational rock mechanics and hydrologic tool — that can model facture propagation, resulting seismic signals and pressure - driven fluid flow through a rock mass.

As this water moves through rocks, it dissolves salt compounds and pushes through fractures in the overlying ice to form reservoirs closer the moon's surface, where it is expelled into space when the outermost layer of the crust cracks open and the resulting depressurization of these reservoirs causes water vapor and ice particles to shoot out in the observed plumes.

Players and fans can experience the all - action game in full, alongside two brand new adventures: the ethereal Fractured Worlds — a challenging and empowering new expansion featuring a new chapter in the story of Victor Vran, and Motörhead: Through the Ages — a wild, rock adventure, inspired by, officially endorsed by, and starring, the loudest band in the world.

Fracking (hydraulic fracturing) rock fracturing with pressurized liquid creating cracks in deep - rock formations through which shale gas, oil, tight gas and brine will flow more freely... major part of the Golden Age of Gas

Low - temperature fields can hold a range of resources, held as heat in rocks or from water travelling through faults and fractures.

A mixture of water and chemicals sent through the drill hole at high pressures creates fractures in the rock and allows the trapped natural gas to escape to the surface.

These companies are benefiting from the huge investments needed to explore, produce, process and transport oil and gas unlocked from previously inaccessible dense rock formations through advances in hydraulic fracturing and horizontal drilling, according to the findings by Houston - based energy analyst firm IHS.

Over the past several years, vast caches of natural gas trapped in deeply buried rock have been made accessible by advances in two key technologies: horizontal drilling, which allows vertical wells to turn and snake more than a mile sideways through the earth, and hydraulic fracturing, or fracking.

The «shale gas» is trapped in shales that have generally low permeability (connected fractures) thus preventing the gas from moving through the rock.

Among the country's top 15 states in overall energy production, Arkansas had a more than 400 percent increase in natural gas output from 2005 through 2015 — thanks to safe hydraulic fracturing and horizontal drilling in shale and other tight - rock formations.
