Hydraulic Fracturing– Is it new or old?

High Volume Hydraulic fracturing using slick water and other additives into
lateral sections in unconventional reservoirs at high pressures is new !
Developed over the last decade.
Original Hydraulic fracturing into vertical wells located in conventional
reservoirs at lower pressure is “old”. Developed in the US in the late 1940s.
The two are about as related as a small grocers shop and a hypermarket.
Conventional reservoirs generally allow gas/oil to flow easily once
punctured.
Unconventional reservoirs do not generally allow gas and oil to flow easily
(ultra low permeability) and so require HVHF. As in 20M litres of chemicals,
sand & water per well to be introduced at various stages, at pressures in
order of 6000psi and typically leave 50% of the fracking fluid in the target
formation post frack. This is NEW not old.

“Regulations are Robust” – Aren't they?

UK Gov constantly stating regulations are robust. UK has best in the world
standards. Prime Minister and Ministers precede each new statement with this line.
Regs developed Post Piper Alpha. Entirely self regulatory/goal setting. Primarily
directed at protecting workers and plant. Crucially not public or countryside.
Neither exist offshore.
Gov now determined to remove regulation (streamlining) to maximise interest
from operators in UK onshore. OUGO offering tax breaks of 50% and overseeing
wholesale scaling back of regulatory framework. OSD- scrapped. EA – 2 week
permits (from 3-6months!) by Feb 2014. Same office in charge of both monitoring
regulation and cheerleading for the shale gas industry.
HSE made zero visits to ensure the HVHF wells drilled by Cuadrilla Resources were
constructed according to what had been agreed. – Well Integrity. Zero inspections.
EA “confused” as to what visits it has made and whether they were random or not.
Does not verify fracking chemicals – what they are and in what concentrations.
Trust the operator to say. Does not verify flowback quantity.

“EU Regulations are Robust”–Aren't they?

EIA Directive - 2011/92/UE.( Precautionary principle). 1 Ha size and above. Industry
easily avoids by making pads 0.9 Ha. No need for EIA at all. 4 exploratory pads close
to my home. None with EIA. Precautionary principle means take precautions to
ensure you do not need an EIA ! Where politically required then scoping doc
brought in to significantly reduce the impact of the impact assessment!
WFD - 2000/60/EC (exemptions for oil and gas). Article 11(3)(j) Water injection.
EU- view that exception does not apply. Member states do not agree! Clarification.
MWD - 2006/66/EC. (open to interpretation). Pushed for all waste to be inc. not
just flowback. Finally EA relented but industry now fighting back. June Conf –
Lawyers from London stating clarification urgently needed. They are being
instructed by industry to re-open the MWD. In UK 3.7M litres from PH-1 went into
Manchester Ship Canal after being “treated”. No treatment for NORM. New
methods being sought. EA consider it standard industrial effluent. It’s not. Not
when it can leak 5 miles below the surface!

EA now reducing time to issue Permit from avg 3/6 months (to allow for full
consultations and objections and due process) to 2 weeks under pressure from UK
Gov and OUGO. (streamlining).
Article 1 – The competent authority may reduce or waiver the requirements for the
deposit of non-hazardous waste. EA consider flowback fluid non-hazardous! Lead
at 1438 times drinking water, Cadmium 36 times, Chromium 72 times, Arsenic 20
times, NORM at 90 times max permissible limit. This is “non-hazardous” according
to UK competent authority!
MWD needs specific provision for exploration and exploitation of unconventional
fossil fuels. Specific clarification of the points to ensure compliance is clear for all
member states. Compliance with the MWD needs monitoring and enforcing across
the EU.
Regulations/ Directives come to nothing if they are not monitored, not complied
with and that non compliance is not policed, not punished, not reported !
So is the UK system robust ? Is the EU system robust?

Why do we need Regs at all?

If well integrity not built in (cementing/casing) then the well will leak.
This leakage is vertical and horizontal. The vertical leakage is where fracking
fluid and methane move up the outside of the casing (in the annulus
between) and up to weakest formation. This represents the bulk of the risk
initially post frack.
Horizontal leakage is out of the target formation and through faults/pores
etc. over time. This represents the bulk of the risk over the long term
(decades).
Leaks from flanges/valves etc. on surface – poor maintenance.
Can repair well if leak discovered :APs, CBLs, Acoustic gas detectors etc.
Wells need monitoring over their lifetime – and not just their commercial
lifetime (which can be as short as twelve months as drop off can be rapid)

So what if a well leaks- does it matter?




Methane is a much more potent greenhouse gas than CO2 Approx. 20 times more. So
all the green “advantages” of burning gas than coal eliminated in event of such
leakage. Worse – It makes shale gas “dirtier”.
Fracking fluids contain substances that if contaminating the aquifer then will spread
over a large area (100s of km2) and pose a significant threat to agriculture, wells and
livestock – i.e. the food chain. Public Health .EU bans. Losses. Compensation.
One well will leave 10 million litres of fracking fluid in the ground. Just one
exploratory well leaking has the potential to cause widespread damage to the
environment and poses a risk to public health.
Just the one and only well fracked in the UK so far (PH-1) 200m from Weeton Village
and 5 Km from Blackpool (pop 250,000) caused two tremors at 1.4 and 2.3 ML and
damaged the well over a very large interval with severe deformation for 240 ft.


Baseline methane, production and legacy,
flowback qty verification, flowback recycle, storage & disposal,
seismic TL,
bond for abandonment,
flaring,
ORIS – New body required to Inspect, Tests and Verify. Planning Assistance,
Public Liaison. Funded by levy with no taxpayer input. Need a robust
inspection regime with maintained by random visits to CBL, FIT, Cementing
etc. and testing of cement samples, mud, chemicals for fracking and
verification of flowback qty etc.

Wireline. Density uses gamma source Cs137 2 Curies. This is a category 3
source – Permanent injury/Death. Porosity uses Neutron AmBe-241 (8 – 23
Curies). This is a category 2 source – Death.
Main Issues : Keep away whilst logging. Security.

Regs for more than just leakage!
 So we need regulations for traffic and flaring too. Maybe EU
considers these local state issues but if local states not protecting
citizens then EU needs to step up and take responsibility.
 No need to flare off. Can green tank and separate, compress and
transport off. Only need for safety flare (approx 1m height) not
20m but need to define the process and regulate it.
 Private companies will not do this without enforcement. Why
should they? Hits profits, hits investment, hits share price – costs
money and if your competitors not doing it then why should you?

Conclusion
 Regulations need to be developed to cover exploratory, field
development plan and production stages. Not just production!
Fracking a few hundred meters from 2,500 homes in Lytham
St.Annes. 20M litres/well. If well leaks then large area at risk.
 Existing regulations are not sufficient (or in need of additional
clarification) for the new practice of intensive HVHF onshore and
in close proximity to large urban conurbations.
 The inspection and monitoring needs a considerable amount of
work to move from the self-regulatory model to a more balanced
approach between prescriptive and goal setting. With frequent
random inspections by completely independent monitors
(commercially, reporting and technically).

Conclusion
 Need enforcement to be coupled with compliance. Proportionate fines,
licenses revocation and criminal proceedings.
 Shale gas and other unconventional fuels are seen by some (inc. entire UK
Gov) as a fantastic opportunity for the member states but from my research I
know it needs close monitoring to prevent an environmental catastrophe and
serious risk to public health.
 EU must act now not wait for production. Exploratory phase is under way.
Regs and monitoring needed in place now for this phase. To protect public
and environment and to be ready for scale up to FDP and production. The
directives need urgent updating and clarification to cope with this industry.
This needs to be achieved with the assistance engineering/science to ensure
relevance and effectiveness.

And Finally…
Shale gas and unconventional fossil fuels may make considerable revenues for
member states. They may assist in energy security. They could help reduce CO2
emissions. They could assist in a transition to renewables and carbon free power
generation. It could be done in a safer manner. Not safe – but much safer.
However, this is not happening. Not the way the EU and in my own state, the UK,
are proposing to develop it. Quite the opposite. We are heading towards
increasing CO2 emissions, diverting valuable resources and attention away from
renewables, risking public health, damaging the environment, destroying jobs
(tourism/farming), industrialising whole areas of countryside, causing havoc to
local communities (as in millions of people) and for what? To make some extra
profit for the few at a great cost for the many.
