Decision delayed again! & Regulatory loophole

Dear BOW followers,

The date for Surrey County Council Planning & Regulatory committee meeting where the current Brockham oilfield application will be decided has been postponed again! It is the third delay (from the original date in May), and decision is now due on the 8th of August.

 Three new documents were added on the 13th of June to SCC planning portal for this application, and one of them has been updated just yesterday (the documents concern emissions to air from gas engine and flare, and we will write more on this next), so we suspect that the reason for delays is the lack of sufficient information and tardiness on the part of Angus Energy in supplying it.

 This is something of a pattern and it appears that, following the revelations of unauthorized drilling in January 2017 against the council’s advice, the attitude of Angus Energy towards the regulators has not become any more transparent. The Brockham site is also going through a re-permitting process by the Environment Agency; the initial consultation closed in early September 2017, but the permit has not yet been determined because, as we were told by the Agency, they have not yet been provided with sufficient detail.

Meanwhile, we have discovered a loophole in the regulatory system (which we also wrote about previously). This loophole allows for various activities to take place without the operator having to notify the Environment Agency and without monitoring, until the modern-standard permit is put in place. These activities include acid stimulation, hydraulic fracturing and water re-injection. Our concern is that, if the current planning application for well BRX4Z targeting the Kimmeridge Clay Formation is approved, Angus Energy will be able start stimulation without any environmental monitoring and without us knowing! If you would like to read more about what we discovered, please see this recently published Drill Or Drop? article.

On a different note, below is a picture from last Saturday, when BOW welcomed in Brockham cyclists from the Tour de Frack UK. The ride was organised to highlight the threat of the industrialisation of our countryside, and passed also by the Horse Hill, Balcombe and (planned) Leith Hill drilling sites.

Horse Hill and UKOG

Long-term flow tests of the Kimmeridge layers have just started at the Horse Hill site, which is operated by UK Oil & Gas (UKOG). UKOG applied to the High Court for an injunction that would effectively stop any campaigning that affects its economic interests. The company since amended the order, but it still seeks to cover “lawful activities” threatening penalties including prison for anyone who breaches it. The injunction hearing is on Tuesday, 3rd July at 1pm and support is welcome. Here is the event Facebook page and article by one of the brave defendants who decided to fight it. UKOG are currently not involved at Brockham.

Dear BOW Supporter,


We are very grateful to David Smythe, Emeritus Professor at the University of Glasgow, who submitted his expert technical commentary in support of our representation to Surrey County Council on the current application. Prof Smythe highlights that inadequate information has been shared with the council for a reliable assessment to be made. His analysis of the available detail concludes that sidetrack BRX4Z was drilled close to a major fault possibly targeting the damage zone of the fault to increase the flow (to emulate the results at Horse Hill-1, nick-named the Gatwick Gusher). This carries an environmental risk, because if any kind of stimulation is applied, the fault zone may become permeable and therefore be a ‘fast track’ to the near surface environment.

Prof Smythe says also that the applicant’s arguments that stimulation of the Kimmeridge Clay Formation (the target of BRX4Z), whether by acidisaton or by fracking, will not be necessary are incredible, because they run counter to the known geomechanical properties of the KCF, and because they conflict with the extensive experience of similar unconventional plays in the USA.


Angus Energy admit that the target Kimmeridge layers are an interbedded shale and limestone hybrid reservoir, yet they describe themselves as a ‘conventional’ oil & gas company at every opportunity, and re-iterate that there will be no hydraulic fracturing because the Kimmeridge is naturally fractured. Professor Smythe points out that the natural fractures (which are visible in the outcrop at the Kimmeridge Bay) are vertical, so it is difficult to see how lateral drainage (from a near vertical well) of the reservoir can be achieved. In any case, even if an unconventional reservoir is naturally fractured, it will still require the drilling of back-to-back wells in order to drain the fractures efficiently, and it will likely require acid stimulation. (1)

Acid stimulation is a type of fracking performed on limestone or sandstone-rich shale that dissolves the rock enlarging or creating new fractures. Unfortunately, acid stimulation, like hydraulic fracturing using fluid volumes below the arbitrary threshold set out in the Infrastructure Act 2015, is exempt from the Government definition of ‘associated hydraulic fracturing’, and from the regulations introduced by the IA2015.



Read here Drill Or Drop Article on this loophole in the system

Meanwhile, we’ve also been in close communication with the local Environment Agency team, who shared their comments to SCC on the current planning application with us. The EA is currently reviewing the existing environmental permit at Brockham as part of a national review to bring all permits to a modern standard. This process started some time ago for Brockham, and there was already one public consultation in July 2017; but because of gaps in information provided by the applicant, the EA has had to request more detail and so the re-permitting process continues. There will be a second consultation once the additional information is submitted, and the earliest this can happen is July 2018. The permit would not be issued until the results of the consultation are evaluated and the assessment is complete.

There is therefore a mismatch between the timescales for the consideration of the planning application to be decided on 20th June and the re-permitting process currently being undertaken by the EA. The EA do not yet have the information that they need to assess the activities proposed by Angus, to decide whether to grant a permit, and to set the terms and conditions for such a permit. 

 In particular, the EA lists the following items that are yet to be determined:

  • Whether what Angus Energyis proposing constitutes appraisal or production from the Kimmeridge Clay Formation.
  • How much gas will be produced from the Kimmeridge formation, and whether the flare falls into the emergency only category or if it may be used for gas disposal.
  • Whether any stimulation is proposed (stimulation includes processes such as matrix acidising, acid fracturing or hydraulic fracturing) to appraise the Kimmeridge Clay Formation and what activities are underway in the Portland Formation.
  • What is the composition of fluids to be re-injected at Brockham (is it produced water, or flowback from stimulation activities; is it from Brockham only, or from other wellsites, such as Lidsey as well)

 Until the new permit is in place, the site operates under the old-style permit, under which none of the above is either clarified or monitored. This means that Angus can carry out stimulation (with acid or hydraulic fracturing) so long as the volumes of fluids injected are below the levels specified as ‘associated hydraulic fracturing’ in the Infrastructure Act 2015, and they will not even need to notify the EA of what they are doing. This is all the more worrying because there is no groundwater monitoring in place at the moment, even though it will be required going forward because of the risk of pollution from re-injection. There is no air quality monitoring in place either, but this will also be required as part of the new permit. Until then, monitoring of site activities can only be carried out via site inspections and verbal interaction with Angus staff. Given the track record of Angus Energy, we are very concerned about this.

With decision on this application postponed again until 11th July, comments are received until 12 noon on 10th July. Please see here on how to object.

Dear BOW Supporter,

There’s been a number of updates since we wrote last on 17th April, day before the official deadline to comment on the current application from Angus Energy covering the drilling and appraisal of unauthorised sidetrack BRX4Z drilled January 2017 (MO/2018/0444). We are sharing some today.


This application was going to be voted by the Surrey County Council Planning and Regulatory Committee on 23rd May, but this has now been moved to the next P&R Committee meeting on 20th June. 

This is good news because we now have longer to make comments, and if you have not commented yet, there is still time. Representations will be received until noon on 19th of June. See our website here for instructions.


Mole Valley District Council, who is a statutory consultee on this application, discussed it on 2nd of May and voted unanimously to object on the basis that the 3-year period proposed by Angus is unnecessarily long to appraise as well (our note: this needs to be seen in the context of Angus making repeated statements over the past months and as recently as late April about putting BRX4Z “straight into commercial production”). MV councillors also raised concern over the potential use of acidisation, emissions from the flare stack, and lack of a risk assessment, as well as the need for close monitoring given the track record of the applicant.

Linkto MVDC statement

Link to GetSurrey and Drill Or Drop Coverage



Drill Or Drop reported on May 8th that Angus had complained to Ofcom about BBC’s reporting of the drilling of BRX4Z, and that this complaint has not been upheld. Ofcom said that BBC had not been unfair to Angus and that its report reflected the company’s position adequately and fairly. Angus were represented by Schillings International LLP – international privacy and reputation law firm that has represented many high-profile clients including celebrities, sports starts and other famous people.

We note that this article in The Times says it is still the subject of a legal complaint from Angus Energy plc.

Link to BBC report on drilling of BRX4Z



Angus Energy announced today that they received approval from Oil & Gas Authority to become the operator of Balcombe (taking over from Cuadrilla).

Here is a quote from Jonathan Tidswell, CEO of Angus Energy from a recent investor show: “The idea of taking over is that we are a non-fracking company. The idea will be to somehow convince the locals over the next few months that there will never be any fracking on the site.”

We believe what might be meant by fracking in this quote is ‘associated hydraulic fracturing’ as defined by the Government in the Infrastructure Act 2015. This definition leaves out a lot of fracking activities that do not meet the definition’s very high thresholds of injected fluids. You can read more on this issue in very digestible format here and here.

Crowdfunder to defend against UKOG injunction goes live

Weald Action Group, and the six local campaigners who are challenging the UK Oil and Gas (UKOG) injunction, have launched their crowdfunder today to pay for their legal costs.

Ann, Sue, Natasha, Constance, Vicki and Jacqui have courageously stepped forward to fight this High Court injunction.  This injunction could stop the right to peaceful protest and prevent local people raising awareness of the new risky methods of unconventional oil and gas drilling and the industrialisation of our beautiful countryside.

Can you please pledge to support them? It doesn’t matter as to the amount. EVERY BIT HELPS.


These type of injunctions are draconian in its chilling effect, and counter to the right to assembly and the right to freedom of expression.  There is already criminal law to deal with any unlawful activities, and this injunction should have no part in defining what is legal and what is not. It is a blatant attack on our human rights.

If this injunction is granted it could also serve as a precedent for other oil and companies here and around the country. It should be fiercely resisted and we need to raise funds for our legal costs to fight this.

Please do share on your social media and/or forward this email to your friends. It helps SO much.

Here is the shareable Facebook post.  Also click on this search for #injunctioninjustice on Twitter to retweet or create your own using the hashtag #injunctioninjustice and the crowdfunder link

We are all in this together and we can’t do any of this without your support. So please donate now and help to stop this injunction.

Thank you!

Retrospective Application For Disputed Sidetrack at Brockham – Points for Objection

Comments can still be made on this application until 7 August, 12 noon.  Please copy them to

Please also read a related blog written after we have discovered the shocking regulatory loophole at Brockham and received Prof David Smythe’s representation.

Angus Energy are back at their wellsite at Feltons Farm, Old School Lane and have restarted pumping oil from one of their two  existing wells, BRX2Y.

Angus have ALSO submitted a planning application to Surrey County Council, which is in 3 parts for:

  • the retention of their other existing well BRX4;
  • the retrospective regularisation of the side track (BRX4Z) they drilled from this well without permission in January 2017; and
  • appraisal of the production potential from this side track, BRX4Z, for a temporary period of three years.

The middle part is application for retrospective permission for the drilling that Angus did in Brockham last January, which DID NOT HAVE PLANNING PERMISSION

The oil field has been here for years, why are we concerned about Angus Energy now?   This is the oil company that:

  • was told in 2014 by consultants commissioned by Angus itself that there was no planning permission to drill at Brockham.
  • ignored two letters from the planning authority that said it needed planning permission to drill. They drilled anyway and then threatened to sue the council if they said they didn’t have permission.
  • didn’t know which well was which, and set up its rig on the wrong wellhead.
  • requested permission for 24 hour working for safety reasons, but but it appears this was to disguise the drilling of a new well all through the night, and over the following 6 days and nights, in contravention of conditions of the permission they were thought to be working under.
  • when local people asked what the noise, lights and activity in the middle of the night were, told the Council it was “Security Lights”. But it wasn’t, they were drilling a new well!

What have they done, or say that they are going to do, for the Brockham village? Absolutely nothing. They have also declined to present their proposals to villagers in a meeting.  So why should they be granted planning permission?

We believe Angus are not responsible operators and this application should be refused. (For more on the history of Angus at Brockham, click here).

Among other issues that you may wish comment to the planning authority on are:

  • Traffic on local roads and access to the wellsite. Angus Energy propose up to 24 HGV movements (12 loads) on any day. This is compared to 2 tanker movements per week in recent years. Traffic will be routed from the A24 in South Holmwood along Old School Lane, Root Hill, Red Lane, Blackbrook Road and Mill Road.)
  • The duration of the permission being sought – 3 years. This is considerably longer than is normally required for an appraisal application, typically 4 to 6 months. This application is for appraisal of the newly targeted rocks, but Angus have been telling their investors that they’re going straight into commercial production.
  • The possible future use of acidisation and/or fracking to “stimulate” the flow of oil from unyielding rocks (different than those targeted so far). Angus sought permission to use of acid and other dangerous chemicals for well cleaning in their permit application to the Environment Agency, but have NOT mentioned this in their Planning Statement. Although at this stage Angus say that they will not frack, the planning authority would not be able to stop them in the future if they grant this application now.
  • Emissions to air and the treatment of natural gas from the well – Angus Energy propose a 12-metre high emergency flare stack, together with a large (375 kVA) gas powered portable generator to burn off the gas and generate electricity.
  • Flood risk. Angus say in their Planning Statement that the site is “at negligible risk from surface water flooding”, but they have not carried out a formal flood risk assessment.
  • The risk of a major incident. There is no mention of major accident or major incident risk in Angus Energy’s Planning Statement.
  • The UK’s commitments to reducing greenhouse gas emissions in the Climate Change Act, 2008.

Retrospective Application For Disputed Sidetrack at Brockham – CONSULTATION OPEN

Dear BOW Supporter / Follower,

Angus Energy have submitted their long-awaited planning application for the next stage of work at the Brockham Oilfield at Felton’s Farm, Old School Lane. The application is in three parts, and relates to well BRX4 where an unauthorised sidetrack was drilled last January.

Part 1 is for the retention of the BRX4 well. The well was drilled in 2007 under a planning permission that expired in 2008. According to the conditions relating to this permission, the well should have been sealed up and the land returned to its former condition, but this has not happened, and Angus are now applying for permission to retain the well for a further 3 years.

Part 2 is a retrospective application for permission to drill the sidetrack to well BRX4, BRX4Z (the unauthorised drilling that took place last year).

Part 3 is an application for appraisal of the production potential of the sidetrack BRX4Z using the production plant and equipment within the existing site plus some additional plant and equipment. Angus is applying for permission to undertake this work over the next three years, and they say that they plan to produce oil from the well for up to 18 months, during which time they will monitor the pressures and the flow. This information is to be used for a report to the Oil & Gas Authority and to inform a further planning application for production, should the appraisal show that there is oil in commercially recoverable quantities.

What will happen if the planning application (or parts of it) are refused

We do not know what will happen, but it is likely that Angus would appeal. If the appeal is successful then a Planning Inspector will grant planning permission. If it is unsuccessful, then enforcement action could be taken by Surrey to have the well shut down and sealed. However, the other two wells (BRX1 and BRX2Y) have a planning permission to produce oil until 2036, so it is unlikely that the whole wellsite would be restored for some considerable time.

What will happen if the planning permission is granted

The planning permission applied for will have a life of three years, during which time Angus would have permission to undertake the appraisal work on well BRX4Z outlined in Part 3 above. If it is successful, we should expect Angus to submit a planning application for further production in 2021, probably for the period up to 2036.

How you can comment on this planning application

The planning authority that will determine this application is Surrey County Council. You can find details of the application on Surrey County Council’s website here, or on Mole Valley District Council’s website here. Surrey County Council’s consultation period opened on 20 March and closes on 18 April. Representations can be made on the Council’s website, or by email to, but remember to include the application no/reference MO/2018/0444 / SCC Ref 2017/0215, your name and address and to state that you are a local resident.

If you wish to make a representation to Mole Valley Council, this should be sent to them by 6 April, but be advised that they will not be determining the application. They simply provide their own response to Surrey.

Key issues that you may wish to consider

Environmental Impact Assessment: Surrey has provided an EIA Screening Opinion that EIA will not be required. We do not agree with this, on the basis that there could be significant environment effects, and that the precautionary principle should apply.

 Target strata and extraction methods: Angus’ proposed targets are the conventional reservoir of the Portland Sandstone, and also the Kimmerdge Clay Formation, an unconventional shale reservoir beneath it. All of the oil extracted from Brockham since the 1980s has been from the Portland. However, the main interest of oil companies in Surrey and Sussex more recently has been the Kimmeridge. We believe that, in order to extract oil in commercial quantities from the Kimmeridge, permission to use unconventional methods such as the use of acid stimulation and/or fracking may be sought. However, at this stage, Angus say that they have no plans to use such methods at Brockham and that they will only need to use acid wash (done with smaller volumes and at a lower pressure than stimulation). The planning authority confirmed to us that should Angus decide they wish to frack or acid stimulate after this application has been approved, there will be no requirement for a fresh planning application..

To watch a video recording of recent talk by David Smythe, Emeritus Professor of Geophysics at the University of Glasgow. This talk is mainly about Leith Hill, but Prof Smythe explains why the Kimmeridge is unconventional and why it’s likely to require extraction methods such as acidising or fracking:

Length of the appraisal phase: As mentioned above, this application is for a period of three years, and Angus say that they plan to produce oil from the well for up to 18 months. In our view, the length of time proposed is excessive and completely out of line with the appraisal programmes of other operators in the Weald Basin, who have typically applied for a period of 4 to 6 months for appraisal works.  For example, the recently approved well-testing application at Horse Hill was for 150 days (i.e. 5 months). Furthermore, we would draw your attention to the fact that Angus Energy has been telling investors for months that they plan to go straight into production on well BRX4Z. This is also corroborated by the fact their initial submission described the works as “production evaluation” and had to be revised before it was validated.

 New plant and equipment: Angus propose to bring new plant and equipment onto site to deal with any gas from the well. They propose a portable generator and an emergency flare stack. The indicative plant proposed in the application is a 375kVA generator, approximately 6m long, 2.4m wide and 2.6m high, and a flare stack and shroud, 12 m high and 2m diameter. This is to convert and burn off excess gas, which is expected to be present in higher quantities in the Kimmeridge.

 Road traffic: Angus say that the operations for which consent is sought will result in no more than 12 loads (24 HGV movements) on any single day, and that it is likely that daily movements will be significantly below this figure. These figures should be compared with the figure of 2 tanker movements per week for traffic using the wellsite in recent years. The designated route to the A24 is via Root Hill, Red Lane, Blackbrook Road and Mill Road.

Environmental permitting: Oilfield operations require an environmental permit from the Environment Agency which is a separate regulatory system from planning. Angus has an existing permit, but will require it to be updated before the appraisal operations can commence. The application for an updated permit was submitted in July 2017; a new permit has not yet been issued. We will keep people informed of its progress.

Brockham Oil Watch 


Awaiting Planning Application for BRX4Z

Dear BOW Supporter,

We have not been in touch in a while, but things are picking up again.

Angus Energy has recently made two important announcements relating to the Brockham Oilfield. On 25 Oct it announced that it will “submit a normalisation application for the continued surface activities of the production plant required for well BR-X4 and notably, its inclusive sidetrack BR-X4Z.” It remains to be seen whether this will include a retrospective application for the drilling of sidetrack BR-X4Z, and/or an application cover any further exploration, testing or production from that or other wells, as Surrey County Council have requested.
In the meantime, on 23 Oct Angus announced that it has received final approval from the Oil and Gas Authority to begin production from the Kimmeridge shale and limestone layers from well BR-X4Z. This is despite the national planning policy guidance suggesting that such consent should only be issued once planning application is in place.

Angus is planning to start production from the Kimmeridge layers in the first quarter of 2018, i.e. by the end of March. This will require the erection of a tall rig on the site, even if further drilling is not required, so that they can do further work on the well. If it goes according to plan, Brockham will be the first site in the country, where this unconventional reservoir will be put into production. They have also announced that they plan to generate electricity at the wellsite using a compression ignition (i.e. diesel) generator supplied with gas and volatiles drawn from the producing well.  Surrey County Council have informed us that this may need a further planning permission, but to date, no such application has been submitted.

Brockham Oil Watch is in regular communication with the Council, the Environment Agency and Health and Safety Executive regarding the planned operations at Brockham. The Environment Agency is in the process of evaluating Angus’ application for a variation of their existing environmental permit to produce oil and gas. We also understand that the EA will be issuing guidance on how the Agency classifies acidisation processes, and how it monitors oilfield wellsites to ensure that only the operations that are allowed within the scope of a valid permit are actually performed.
