Fracture Growth at Preston New Road

richard parker made this Freedom of Information request to Environment Agency

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was partially successful.

Dear Environment Agency,

I understand that the EA is responsible for the monitoring of the fracture progression at the hydraulic fracking site at PNR.

Could the EA please advise if the seismic activity close to the well that is displayed on the BGS 'British Earthquake' website as activity at Blackpool on and between the 18 to 20 October is on the growth of these fractures, ie on the fracture line. Or are these events away from the fracture lines. In either instance, how far away from the well are they please.

With regard to the fracture progression, could the EA please advise if and when the frack sleeves of a frack are closed following a frack. Please advise if the closure of the sleeves following a frack is time or return pressure dependant and the relevant figures. This pertinent information is not available in the hydraulic fracturing plan but I am sure the EA has considered these aspects to ensure that the frack progression is maintained and appropriately limited.

Please advice as to whether there is evidence to suggest that the fracking fluid has impregnated further into the geology, particularly on the faults/seismic discontinuities labelled SD4, SD5 and SD6 in the hydraulic fracture plan.

Yours faithfully,

richard parker

Dear Enquiries, Unit,

Obviously, since originating this request, seismic activity has been regular and increasing.

Please advise as to the lateral extent of fracture progression along the well and as to whether the seismic epicentres are on fracture lines or are distinctly separate. Also the seismic epicentre location with respect to the fracking sleeve position on the well open at the time of frack, or most recently closed.

In essence, the public need to be reassured that the fracture and epicentres are directly interrelated and the results to be visible and there is evidence that it is being independently monitored and reviewed.

Yours sincerely,

richard parker

Dear Enquiries, Unit,

Naturally, I understand the confidential nature of the fracture progression data, but there appears to be no evidence to the public of what exactly is being monitored by whom and what strategy is being adopted by Cuadrilla to the fracturing. They refuse to large divulge pertinent information.

Please advise what and how you are monitoring wrt the fracture growth and what is reported to you by Cuadrilla.

I would anticipate that you are advised of the time, duration, pressures, chemistry and volumes of each frack. The amount and processing of each flowback. Then analysis of the fracture growth and the correlation between this and the epicentre of the micro earthquakes. Do you do this and how often?

The hydraulic fracture plan is ambiguous into what well is being fractured and the relation of the microseismic monitoring.

Originally, the environmental statement indicated that the Upper Bowland beds were to be fractured first. Now it is evident that the lower beds are being fractured. It is unclear as to if the microseismic down hole array is to be used in both wells. So is the idea to fracture the lower well first with the detection array in the upper well and then switch the array into the upper when fracking the lower?

Are you aware as to the strategy and monitoring arrangements? Are you retrospectively advised or are you involved in the planning of the activities?

Yours sincerely,

richard Parker

Dear Richard

 

Enquiry regarding fracture growth at the Preston New Road site

 

Thank you for your emails dated 23 and 29 October 2018. Please accept our
apologies for the delay in our response.

 

We respond to requests under the Freedom of Information Act 2000 and
Environmental Information Regulations 2004.

 

Please see our response below to the questions raised in your emails.

 

Q. I understand that the EA is responsible for the monitoring of the
fracture progression at the hydraulic fracking site at PNR.

A. The Environment Agency is responsible for ensuring the operator uses
appropriate methods to monitor fracture growth.

 

Q. Could the EA please advise if the seismic activity close to the well
that is displayed on the BGS 'British Earthquake' website as activity at
Blackpool on and between the 18 to 20 October is on the growth of these
fractures, ie on the fracture line. Or are these events away from the
fracture lines. In either instance, how far away from the well are they
please.

A. The seismic activity at Blackpool on those dates, is considered to be
likely to be associated with the fluid injections. Events reported by the
British Geological Survey (BGS) are located in a similar manner to those
recorded on the established ‘Traffic Light System’ (TLS) which uses
similar instrumentation. Another method of measuring the position of the
event sources underground is available from the microseismic monitoring
array, which uses different instrumentation and is much closer to the
event sources. Our checks on the microseismic activity of very small
microseismic events (typically of Magnitude minus 2.5 to minus 0.5)
related to the effect of fluid pressure splitting the rock, show that the
TLS events are also detected as part of this microseismic activity. 

 

Q. With regard to the fracture progression, could the EA please advise if
and when the frack sleeves of a frack are closed following a frack. Please
advise if the closure of the sleeves following a frack is time or return
pressure dependant and the relevant figures. This pertinent information is
not available in the hydraulic fracturing plan but I am sure the EA has
considered these aspects to ensure that the frack progression is
maintained and appropriately limited.

A. This information is not included in the Hydraulic Fracture Plan (HFP)
as it is part of the management of the fracturing process that is
determined prior to, and can change during, the fracturing programme.
Details of the fracturing programme are considered by the Oil and Gas
Authority (OGA). The OGA can be contacted at
[1][email address

 

Q. Please advise as to whether there is evidence to suggest that the
fracking fluid has impregnated further into the geology, particularly on
the faults/seismic discontinuities labelled SD4, SD5 and SD6 in the
hydraulic fracture plan.

A. The pattern of microseismic (MSM) event locations gives evidence that
the fractures or minor fault reactivations have not extended as far as the
Permit Boundary. The OGA has compared the position of the larger TLS
events with the position of possible faults, acknowledged in the HFP as
‘seismic discontinuities’ SD4, 5 and 6. If you would like further
information on this please contact the OGA.   

 

Q. Additional query:

Obviously, since originating this request, seismic activity has been
regular and increasing.

Please advise as to the lateral extent of fracture progression along the
well and as to whether the seismic epicentres are on fracture lines or are
distinctly separate. Also the seismic epicentre location with respect to
the fracking sleeve position on the well open at the time of frack, or
most recently closed.

A. As at 12 November 2018, a subset of the available fracture sleeve
positions has been used for injection, between sleeve 1 and sleeve 40. The
large majority of the seismic and microseismic event hypocentres
determined from the MSM array, plotted close to the injection point. 

 

For more information about how we regulate the onshore oil and gas
industry visit our [2]information page.

 

Please refer to [3]Open Government Licence which explains the permitted
use of this information.

 

Please get in touch if you have any further queries or contact us within
two months if you’d like us to review the information we have sent.

Dear CMBLNC Info Requests,

Thankyou for your informative reply.

The general summarise appears to be that the seismic activity is attributable to fluid injection either instigating intentional micro fracking but also , in the case of larger seismic events, instigating fault reactivation.

I appreciate that the majority of the event hypocentres are inside the broad 'frack arc' and are largely close to the injection points. However, I note that you state that the large majority of events are inferred to be close to the injection points but not all of the events. Please could you advise as to the location of the seismic events over 0.0 with respect to the fluid injection point(s) used prior to these events occurring. This information appears to be particularly pertinent to the 0.7 'latent' event registered on 4 Nov 2018.

The delineation of monitoring, implied responsibility and information availability of the seismicity and fracture growth experienced at Preston New Road between the EA and OGA appears confusingly. A similar request to provide seismic information to the OGA has been met with a response implying that no information is yet available to disseminate.

Thankyou again for providing some of the preliminary details of the seismic activity. With the cessation of fracking activity since early November, I would be welcoming and am anticipatory of any report detailing the correlation of the seismic event hypocentres, fluid injection points and any resulting inference to the fault geology. Please advise as to if and when this information is to be made available.

Yours sincerely,

richard parker

Dear Richard

 

Enquiry regarding fracture growth at Preston New Road

 

Thank you for your enquiry which was received on 3 November 2018.

 

We respond to requests under the Freedom of Information Act 2000 and
Environmental Information Regulations 2004.

 

Please see our response below to the questions raised in your email.

 

Q. Please advise what and how you are monitoring wrt the fracture growth
and what is reported to you by Cuadrilla.

A. We receive a daily report with key details on the progress of the
fracturing, and additional data in exceptional situations as described
below.

 

Q. I would anticipate that you are advised of the time, duration,
pressures, chemistry and volumes of each frack. The amount and processing
of each flowback. Then analysis of the fracture growth and the correlation
between this and the epicentre of the micro earthquakes. Do you do this
and how often?

A. The monitoring data is summarised in a morning report to the
regulators, which we receive daily, having a content listed in section 6
of the Hydraulic Fracture Plan (HFP). Other details are added as
necessary. If there is a Traffic Light System seismic event, the
procedures laid out in the flowchart in Appendix 4 of the HFP are
followed. The hypocentres (sub-surface positions) of the larger seismic
events and microseismic event locations have been compared with the daily
reported fracture extent diagrams at site visits, and there have been no
indications of fractures extending beyond the permit boundary. 

 

Q. The hydraulic fracture plan is ambiguous into what well is being
fractured and the relation of the microseismic monitoring.

A. The HFP for PNR1z includes this in the title of the document. The
seismic monitoring array is in the observation well (as mentioned in
Appendix 3) which is PNR2.  

 

Q. Originally, the environmental statement indicated that the Upper
Bowland beds were to be fractured first. Now it is evident that the lower
beds are being fractured. It is unclear as to if the microseismic down
hole array is to be used in both wells. So is the idea to fracture the
lower well first with the detection array in the upper well and then
switch the array into the upper when fracking the lower?

A. Yes, this is correct. The HFP for fracking well PNR2 has not been
finalised yet, but we expect that it will describe the use of the PNR1
well for the monitoring array. The PNR2 lateral is in the Upper Bowland
Shales.

 

Q. Are you aware as to the strategy and monitoring arrangements? Are you
retrospectively advised or are you involved in the planning of the
activities?

A. We are fully aware of the strategy and monitoring arrangements, and the
processes of designing and verifying monitoring arrangements that meet the
regulators’ requirements have extended over some months.

industry visit our [1]information page.

Dear Richard

 

RE: Request for information under the Freedom of Information Act 2000
(FOIA) / Environmental Information Regulations 2004 (EIR)

 

We refer to your request for information of 24 November 2018 regarding
Cuadrilla, please see your email below.

 

We respond to requests for information that is held under the Freedom of
Information Act 2000 (FOIA) and the associated Environmental Information
Regulations 2004 (EIR).The information you have requested is environmental
and we are therefore considering your request under the provisions of the
EIR. 

 

Normally our response would be due on 24 December 2018. However due to the
nature of the information requested, we are unable either to comply with
the request within that period or to make a decision to refuse to do so. 
As allowed for under EIR regulation 7, we are therefore extending the
period within which we will respond from 20 working days to 40 working
days. We will therefore respond by 24 January 2019. We will of course
endeavour to respond to you before then if we can.

 

If you are not satisfied with our decision to extend the time for our
response you can contact us to ask for our decision to be reviewed. If you
are still not satisfied following this, you can then make an appeal to the
Information Commissioner, who is the statutory regulator for Freedom of
Information.

Dear Richard

 

RE: Request for information under the Freedom of Information Act 2000
(FOIA) / Environmental Information Regulations 2004 (EIR)

 

We refer to your enquiry dated 24 November 2018 regarding Cuadrilla.
Please also refer to the emails we sent you dated 24 December 2018 and 23
January 2019. Please accept our apologies for the delay in our response.

 

As advised previously we are in a process of determining confidentiality
under the Environmental Permitting Regulations 2016 (EPR). When we reach
our determination under Regulation 51 of those Regulations we must give
notice of that and our reasons to the operator. We are currently due to
issue our determination by 29 January 2019. After that we must not include
information on the public register for another 15 working days. During
that period the operator can give notice of appeal under Regulation 53 and
if we receive such a notice we must not include the disputed information
on the public register until the appeal has been determined. We will not
disclose disputed information under the EIR either until the 15 days has
expired and we have received no notice of appeal, or, if there is an
appeal, until the appeal is determined – if the inspector determines that
information should be included on the public register.

 

However in the meantime we are now collating and redacting the daily
reports so as to disclose some information from them to you, whilst at
present withholding the information that is subject to the procedures
under EPR Regulations 48-54. We will provide you with this information in
due course.

Dear Richard

 

Enquiry regarding the Preston New Road site

 

Thank you for your enquiry which was received on 24 November 2019. Please
accept our apologies for the delay in our response.

 

We respond to requests under the Freedom of Information Act 2000 and
Environmental Information Regulations 2004.

 

Please find attached a summary table of those seismic events detected by
the ‘Traffic Light System’ for which we have had event reports.

 

Fracking has recommenced and finished on the well PNR1z since your
enquiry. The location of known faults has been taken into account in the
assessment of risk and the microseismic event clusters do not imply that
the faults interpreted from surface seismic data have reactivated. 

 

Further information on possible reactivation of other faults that were not
detectable in the 3D seismic exploration data, would require analysis of
the microseismic event build up, magnitude distribution, and event cluster
development.

 

For more information about how we regulate the onshore oil and gas
industry visit our [1]information page.

 

Please refer to [2]Open Government Licence which explains the permitted
use of this information.

 

Please get in touch if you have any further queries or contact us within
two months if you’d like us to review the information we have sent.

Dear CMBLNC Info Requests,

Thank you for your latest response though it seems confused concerning the distinction between micro seismic activity as an expected consequence of fracturing and the (amber level) seismicity caused due to fault reactivation as an unintentional consequence of the fracking.

From your response, it would suggest that the amber level seismicity is a consequence of fault reactivation of faults that have not been discernable from the initial interpretation of the geophysical data used to map the fault topology. Could you please advise as to the efforts to resolve the causative source of this amber level seismicity. Has the operator (Cuadrilla) under the vigilance of yourselves attempted to resolve the fault geometry to explain the origin of the seismicity? Please advise as to what levels of seismicity can be expected in the event that the (presumably) known larger faults are reactivated.

Yours sincerely,

richard parker

Dear CMBLNC Info Requests,

From an earlier response it would appear that the EA is responsible for ensuring that the operator (Cuadrilla) is monitoring the fracture progression. Does the EA review any of the fracture progression data that is collated by the operator and attempt to correlate with the relevant source frack sleeve, induced amber/red seismicity locations and the general geographical trend of fracturing?

Please advise as to why the fracture direction has a largely northerly, easterly and downwards progression.
(As indicated from the daily reporting of fracture growth provided by the operator).

Please advise as to the fracture sleeve geometry, whether this relates to the fracture progression or whether it is inferred that the fracture progression is a result of the regional geological stress geometry.

Please advise as to the location of which fracture sleeve was open or most recently opened at the times of amber and red seismic activity rather than the frack sleeve closest to the location of the seismicity. Please advise as to these frack sleeve locations.

Yours sincerely,

richard parker

Dear Richard

 

Enquiry regarding the Preston New Road site

 

Thank you for your enquiry which was received on 21 March 2019.

 

We respond to requests under the Freedom of Information Act 2000 and
Environmental Information Regulations 2004.

 

Please see our response below in black text, to the questions raised in
your email in blue text.

 

From an earlier response it would appear that the EA is responsible for
ensuring that the operator (Cuadrilla) is monitoring the fracture
progression.

Yes that is correct.

 

Does the EA review any of the fracture progression data that is collated
by the operator and attempt to correlate with the relevant source frack
sleeve, induced amber/red seismicity locations and the
general geographical trend of fracturing?

Yes, the Regulators receive a morning report with this information as
required in the Hydraulic Fracture Plan.

 

Please advise as to why the fracture direction has a largely northerly,
easterly and downwards progression.

We do not have a remit to interpret this information, beyond the
observation that the fracture activity is not threatening Permit
boundaries. The Oil and Gas Authority (OGA) are undertaking studies on
this, and expect to publish them later in the year. The OGA can be
contacted at [1][email address

(As indicated from the daily reporting of fracture growth provided by the
operator).

 

Please advise as to the fracture sleeve geometry, whether this relates to
the fracture progression or whether it is inferred that the fracture
progression is a result of the regional geological stress geometry.

The order of use of the fracture sleeves was decided by the Operator for
operational reasons, we understand this took into account the fracture
progression from previous sleeves. We do not have a remit to interpret the
reason for the direction of development of the fractures.

 

Please advise as to the location of which fracture sleeve was open or most
recently opened at the times of  amber and red seismic activity rather
than the frack sleeve closest to the location of the seismicity.

This information is provided in the morning reports, which were sent to
you on 13 March 2019.

 

For more information about how we regulate the onshore oil and gas
industry visit our [2]information page.

 

Please refer to [3]Open Government Licence which explains the permitted
use of this information.

Dear Richard

 

Enquiry regarding the Preston New Road site

 

Thank you for your enquiry which was received on 21 March 2019.

 

We respond to requests under the Freedom of Information Act 2000 and
Environmental Information Regulations 2004.

 

Please see our response below to the questions raised in your email. Your
questions are in blue text and our response in black text.

 

Thank you for your latest response though it seems confused concerning the
distinction between micro seismic activity as an expected consequence of
fracturing and the (amber level) seismicity caused due to  fault
reactivation as an unintentional consequence of the fracking.

There is no confusion. The microseismic event location system also records
the Traffic Light System (TLS) events, and relative magnitudes can also be
established from the microseismic monitoring system allowing an improved
location for the TLS events.  

 

From your response, it would suggest that the amber level seismicity is a
consequence of fault reactivation of faults that have not been discernable
from the initial interpretation of the geophysical data used to map the
fault topology. Could you please advise as to the  efforts to  resolve the
causative source  of this amber level seismicity.

We don’t hold this information. The Oil and Gas Authority (OGA) are
undertaking studies on this, and expect to publish them later in the year.
The OGA can be contacted at [1][email address

 

Has the operator (Cuadrilla) under the vigilance of yourselves attempted
to resolve the fault geometry to explain the origin of the seismicity?

The OGA are undertaking studies on this, please see above answer.

 

Please advise as to what levels of seismicity can be expected in the event
that the (presumably) known larger faults are reactivated.

An estimate of maximum magnitude was included in the original
[2]Environmental Statement e.g. at section 12.6.6, and is also included in
the Hydraulic Fracture Plan for PNR1z. The fault slip potential of the
known faults is also summarised in the Hydraulic Fracture Plan.

 

For more information about how we regulate the onshore oil and gas
industry visit our [3]information page.

 

Please refer to [4]Open Government Licence which explains the permitted
use of this information.

 

Please get in touch if you have any further queries or contact us within
two months if you’d like us to review the information we have sent.
