Sentences with phrase «wastewater injection volume»

The results showed that the spatial correlation between earthquakes and wastewater injection volume indeed decreased in 2016.

The new study is part of a larger effort that Pollyea and his collaborators are pursuing to study fluid - triggered earthquakes and wastewater injection volume and their relation to population centers in Oklahoma, building codes, policy decisions, and industry regulations.

«When we compared the spatial correlation using datasets that include only magnitude 3 - plus earthquakes, there was no change,» said Pollyea, adding that a larger reduction in wastewater injection volumes is needed to reduce the dangers of large magnitude earthquakes.

Not exact matches

Since 2015 Oklahoma has slashed injection volumes and, in some cases, suspended wastewater disposal near seismic zones in an effort to mitigate the quakes.

Abers and his colleagues dug up data on the rates and volumes of liquids associated with the wastewater injection sites.

This study is the first to show the extent of the impact of wastewater injection wells at Kahului Wastewater Reclamation Facility, Maui's highest - volume sewage treatment plant, on Kahului Bay.

In a new study, Virginia Tech researchers have found that efforts to curb earthquakes triggered by the injection of oilfield wastewater into the ground in Oklahoma are not targeting the most dangerous tremblers, and that a larger reduction in injection volumes is needed.

They used the model to estimate stress changes induced in the area by two wastewater injection wells and the more than 70 production wells that remove both natural gas and significant volumes of salty water known as brine.

Previous attempts to model the relationship between injection of wastewater and the triggering of earthquakes suggested that the maximum magnitude of the seismic activity induced in this way would be proportional to the volume of the fluids injected.

The suspected culprit is fracking — or more specific to this case, the three injection wells in the area, which inject «vast volumes of salty, chemical - laced wastewater» deep into the ground.
