Did UKOG use matrix acidising?
The UKOG statement implies that matrix acidisation may have been used at Broadford Bridge. A coiled tubing unit was used at the site, which could indicate that the process was carried out. But a company review of the Broadford Bridge operation said “acidisation was not selectively administered to any specific limestone horizon”. Drill or Drop asked UKOG twice to clarify whether or not it carried out matrix acidising at Broadford Bridge. UKOG did not reply.
Did UKOG have permission to use matrix acidising?
UKOG said in its statement that the process that it referred to as matrix acidisation “was fully permitted and approved by the Environment Agency”. We asked the Environment Agency (EA), which is responsible for regulating the use of acid, whether UKOG had permission for matrix acidisation. It said:
“No such groundwater activity was applied for and was therefore not included within the environmental permit for the site.”
In the first significant check on the Trump administration’s “energy-first” agenda, a US judge has temporarily halted hundreds of drilling projects for failing to take climate change into account.
The introduction of Team Ineos into the professional peloton at the Tour de Yorkshire is set to be greeted with protests by anti-fracking campaigners.
Anti-fracking group Free Frack United has confirmed that these protests will continue and says it will be present at the Tour de Yorkshire when Team Ineos is officially unveiled.
Fracking has created a “real shadow across the landscape” for those communities affected by exploratory drilling, a Tory MP has warned.
Lee Rowley argued a law change was needed to limit the “ability for seismic activity to take place over and above what the regulations already say”.
An engineer who has called for stricter regulation of fracking was subjected to a public campaign to discredit him, a disciplinary investigation by his professional body has noted. But after two 18+-month investigations, the IET has cleared him twice on all counts.
A parliamentary bill to limit earthquakes caused by fracking has passed its first stage unopposed today.
There were 39 small earthquakes in the second half of October 2018 across the UK. Thirty-three of them were within a few miles of Blackpool Tower. We found out later that the company trying to frack had gotten less than 10 per cent through its planned industrial processes. As a result, the industry immediately threw its toys out of the pram and demanded the government raise the level of earthquakes it was permitted to generate from its activities.
People have been excluded from a public consultation over fracking chemicals by the use of technical language, an industrial chemist has complained.
Dr Duncan Coppersthwaite, a member of the Royal Society of Chemistry and a chartered chemist, accused the Environment Agency, which organised the consultation, of failing to provide a fair and open process.
His complaint centres on Cuadrilla’s use of the phrase “non-hazardous” for two additives it wants to use in fracking at its Preston New Road site near Blackpool.
