Fracking site in UK suffered possible “loss of wellbore integrity”

According to reports and information gained under the UK Freedom of Information Act it appears that one of Cuadrilla’s initial drilling sites in the UK suffered a previously unreported structural failure.

The damage has been described by engineers as a possible “loss of wellbore integrity”, this can result in a leaking of fluid or gases from shale extraction and cause possible environmental or public health hazards.

The allegations originate from emails between Cuadrilla and the Health and Safety Executive (HSE) which suggest that the site at Preese Hall, Lancashire, suffered structural damage.

The news has caused environmental and safety concerns regarding fracking, although there is no indication that any gases escaped from the well into the air or surrounding rocks.
