Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate his Department has made of the number of onshore wells needed to be hydraulically fractured in the UK between 2018-2038 to replace 50 per cent of the UK's natural gas demand.

The Department for Business, Energy and Industrial Strategy has not made any estimates on the proportion of UK gas demand that could be met from UK-sourced shale gas.
