The intensification of the water footprint of hydraulic fracturing

by A.J. Kondash et al., August 15, 2018 in ScienceAdvances


Abstract

Unconventional oil and gas exploration in the United States has experienced a period of rapid growth, followed by several years of limited production due to falling and low natural gas and oil prices. Throughout this transition, the water use for hydraulic fracturing and wastewater production in major shale gas and oil production regions has increased; from 2011 to 2016, the water use per well increased up to 770%, while flowback and produced water volumes generated within the first year of production increased up to 1440%. The water-use intensity (that is, normalized to the energy production) increased ubiquitously in all U.S. shale basins during this transition period. The steady increase of the water footprint of hydraulic fracturing with time implies that future unconventional oil and gas operations will require larger volumes of water for hydraulic fracturing, which will result in larger produced oil and gas wastewater volumes.

Plans to frack UK’s first horizontal shale gas well submitted

by BBC, May 21, 2018


The well has been drilled through the Lower Bowland shale at a depth of approximately 2,700m (8,860 ft) below ground and extends laterally 800m (2,620 ft).

Francis Egan, chief executive officer of Cuadrilla, said the government’s recent announcement underlined the “national importance of shale gas”.

“We are now very close to demonstrating that Lancashire shale gas can be commercially developed in a safe and environmentally responsible manner.”

The firm said drilling on a second horizontal shale gas exploration well at the site is due to be complete soon when it will lodge a second fracking application.

It said it expects to start fracking both wells later this year.

U.S. exported more natural gas in 2017 than it imported for the first time in 60 years, according to the Energy Department.

Natural gas production has boomed in recent years, particularly in Pennsylvania and other parts of Appalachia, thanks to hydraulic fracturing or fracking and horizontal drilling. The boom has offset Canadian imports and allowed U.S. companies to ship more fuel abroad.

Fracking firm Cuadrilla to reignite West Sussex plans

by Jillian Ambrose, January 9, 2018, in TheTelegraph Business


Cuadrilla will be allowed to test wells in the Sussex countryside until 2021 to see whether the fossil fuel flows from underground limestone rock could be a commercial source of homegrown energy.

The unanimous approval of the county council does not include permission to use the controversial process of hydraulic fracturing, or fracking, but is nonetheless likely to reignite local opposition.
