Sentences with phrase «hydrofracture processes21»

More recent research, however, suggests that collapse could happen sooner; processes such as ice cliff failure and hydrofracture, omitted from most ice - flow models, might initiate a collapse of the Thwaites Glacier within a few decades (DeConto and Pollard 2016, Scambos et al. 2017).

Releasing a huge iceberg, by itself, is a normal process, unrelated to warming, but increased calving may occur in the future if the ice shelf continues to thin, which would make it susceptible to plate bending and hydrofracture processes21.

Indeed, a shortage of accessible natural gas threatens to cause more manufacturing losses in the region, where the state has banned shale gas production via high - pressure hydraulic hydrofracturing.

Several environmental organizations, boosted by the popular movie «Gasland,» have claimed that using hydrofracturing can endanger public water supplies, in part because of potentially toxic chemicals that are sometimes used to help extract the gas.

If so, the interaction between hydrofracturing and ice - cliff collapse could drive global sea level much higher than projected in the Intergovernmental Panel on Climate Change (IPCC)'s 2013 assessment report and in a 2014 study led by Kopp.

Work is underway on how to improve performance of hydrofractures in horizontal wells, Patzek added.

The researchers conclude that well production could be greatly improved if the hydrofractures connected better to natural fractures in the surrounding rock.

«By analyzing the basic physics underlying gas recovery from hydrofractured wells, we calculated a single curve that should describe how much gas comes out over time, and we showed that production from thousands of wells follows this curve,» Marder said.

The time at which gas pressure drops below its initial value everywhere in the rock between hydrofractures is called its interference time.

The study's well sample is made up of about half of the 15,000 existing wells in the Barnett Shale, the geological formation outside Fort Worth that offers the longest production history for hydrofractured horizontal wells in the world.

This publication is a systematic, objective review of documented types and rates of hydrofracturing - fluid - and chemical - related incidents affecting human health, to date, in the region of the Marcellus Shale Play.

For example, some exciting work being done by David Pollard and Rob DeConto suggests that processes such as ice - cliff collapse and ice - shelf hydrofracturing may play important roles in future ice sheet behavior that have not been well incorporated into most ice sheet models.

In hydrofracturing — the process implicated in the infamous break - up of the Larsen B ice shelf in 2002 — rainfall or meltwater that pools on the glacier's surface drains into cracks.

The more dynamic picture in the new simulations suggests that the rate of change in the first half of this century — which does not involve a significant contribution from processes like marine ice - cliff instability, or hydrofracturing — is essentially uncorrelated with the rate of change later in the century.

My husband and I moved here because hydrofracturing pushed us off the family farm in TX 1.5 yrs ago.

Pollard, D., Deconto, R. M. & Alley, R. B. Potential Antarctic Ice Sheet retreat driven by hydrofracturing and ice cliff failure.

It expanded extraction using hydrofracturing in tar sands to increase activity in offshore oil drilling all over the world, thereby maximizing its rate of fossil fuel extraction and processing.

The statistical truth is that hydrofractured wells are marginally productive sources of natural gas and oil.

New, more accurate hydrofracturing (fracking) drilling techniques have opened up enormous, previously inaccessible shale deposits, providing abundant, irresistibly low - cost supplies.

And older climate models did not include dynamic ice sheet vulnerabilities — like high latent - heat ocean water coming into contact with the submerged faces of sea - fronting glaciers, the ability of surface melt water to break up glaciers by pooling into cracks and forcing them apart (hydrofracturing), or the innate rigidity and frailty of steep ice cliffs which render them susceptible to rapid toppling.

These approaches, however, haven't taken into account some physical processes that can quickly increase ice sheet discharge, such as the collapse of terminal ice cliffs and the breakup of floating ice shelves caused by a process known as hydrofracturing.

For example, a recent ice sheet model sensitivity study finds that incorporating the physical processes of hydrofracturing of ice and ice cliff failure increases their calculated sea level rise from 2 meters to 17 meters and reduces the potential time for West Antarctic collapse to decadal time scales.

What if someone decided to include processes such as hydrofracturing and ice cliff failure in these objective models?

Diverting more gas from the domestic energy market would exert even more upward pressure on fuel gas prices, and with gas prices on the rise you're going to start setting more pushback from consumers and less support for fracking (short for hydrofracturing), the shale drilling method that has been causing so many problems in local communities.

The study's major achievement is the addition of two key ice melting processes left out of all Antarctica - wide models to this point: Meltwater ponding and crevasse formation on the surface of ice sheets — so called «hydrofracturing» — and the tendency of ice sheets that are grounded on marine bedrock to rapidly retreat.

The more dynamic picture in the new simulations suggests that the rate of change in the first half of this century — which does not involve a significant contribution from processes like marine ice - cliff instability, or hydrofracturing — is essentially uncorrelated with the rate of change later in the century.

To do so, they had to add two additional, less well - studied mechanisms to their model: «ice - shelf hydrofracturing» and «marine ice - cliff instability.»

Meanwhile, Exxon Mobil was investing its massive $ 45 billion in earnings in maximizing extraction and processing of oil and gas, including the controversial use of hydrofracturing (fracking) to extract fuel from tar sands and the expansion of offshore oil drilling.
