Sentences with phrase «injection volumes»

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

That research was based upon numerical modelling in which a number of factors, including fluid injection volume and rate, and fracture orientation and depth, were kept constant.

Advocating reducing injection volume over time, this study offers new insights into the rationale for a continuing call for reducing injection rate in order to reduce seismicity.»

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.

In their non-public survey, Boehringer Ingelheim reported that dog and cat owners believe that «reduced injection volume over the lifetime of their cat is an important feature in a vaccine».

Since then, the state has asked that more than 600 disposal wells operating in quake - prone areas cut injection volume by 40 percent below 2014 levels.

The task force, chaired by Buchanan, recommended restricting injection volumes within five seismic zones across two counties.

This could allow companies or regulators to take quick action to reduce injection volumes before the quakes grow larger, and Texas is currently installing such a network.

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

In April 2016, Oklahoma Gov. Mary Fallin signed a law authorizing the Oklahoma Corporation Commission to limit injection volumes in the immediate aftermath of earthquake swarms.

«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.

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.

The MPI fuel rail has an integrated low - pressure sensor to regulate the injection volume; the MPI valves are integrated in the Variable Tumble System (VTS) flange.

Once you have established your linear mass on column range, you can adjust standard concentrations and the split ratio (or injection volume) to maximize your calibration range while maintaining sensitivity to meet method required LOQs.
