Brockham Update – Oct 2019

  • After announcing in June 2019 that the company was in preliminary discussions with a third party regarding a sale of its 65% interest in the Brockham license, Angus Energy is no longer actively selling, although a market buyer could still offer to purchase the site and licence. Angus said it received a temporary extension of its production license PL235 from the Oil and Gas Authority (it was due to expire in Oct 2019) but they have not told us the new expiry date.
  • Angus said there was oil in the Kimmeridge shale at Brockham, but “not in sufficient quantity or under sufficient pressure to want to release itself and come up the pipe.” They said there are variations in the Kimmeridge and that it is really an unknown. Multiple wells in multiple locations would have to be drilled to understand how the rock behaves in different areas.
  • Angus confirmed they have ruled out high volume fracking. The Kimmeridge layers are shallower than 1,000m below ground, and high volume fracking is not allowed. They also told Drill Or Drop? that it is too expensive and too difficult to get community support. Angus did not comment on other fracking-like methods such as acid stimulation.
    • Our comment: if there is not enough oil in the Kimmeridge, it makes little sense to try to extract it.
  • Angus says it plans to re-start production from the conventional Portland reservoir via well BRX2. The Portland has already been exploited at Brockham and is towards the end of its life.
  • Angus will need to apply pressure management techniques (namely reinjection of waste water), to produce the Portland. They previously said: “if we can’t reinject we can’t support the pressure in the reservoir and we can’t get rid of any water that has been produced.” Angus said they were in discussions with the Environment Agency to find a way around this technical issue, but no application has been made.
    • Our comment: In November 2018, Angus was granted a new environmental permit by the EA. This permit prohibited the reinjection of waste water (from Brockham and another drill site – Lidsey) at Brockham because of the risk of pollution of groundwater. There is no groundwater monitoring at Brockham, and Angus was not able to demonstrate to the EA that they had the required procedures in place to monitor well integrity when injecting waste water underground.
  • Angus also believe there might an opportunity to access the Portland via the infamous sidetrack BRx4Z drilled without planning permission. Although they also obtained a cost estimate to plug and abandon it.
  • If Portland extraction is not viable, the entire site will be probably abandoned and restored to agriculture.
  • Angus also told the Parish Council that they might target other layers, but no other detail is available.
  • Angus tentatively agreed to form a local liaison committee with the Parish Council and members of Brocham Oil Watch. Meetings of this group would begin in November 2019.

BBC’s “The Corrections” Needs Correcting

Weald Action Group complaint, October 2019

Re BBC ‘The Corrections’ programme on fracking in Balcombe, first broadcast on Friday September 27th, 2019.

1)    The programme was unbalanced. The subject was ‘the incorrect way fracking in Balcombe was reported in 2013’. But no one from the anti-fracking side of the argument was consulted or interviewed. No member of the Balcombe community was contacted, and no Balcombe resident was heard in the programme. The programme focussed on the industry’s view.

2)    The programme was very poorly researched, in so many ways, detailed below, with evidence/links in footnotes.

3)    Pre-broadcast warnings of error and bias went unheeded. Balcombe residents learnt of its intended broadcast and could see the view it would take from the on-line trail. They supplied factual, balancing information and evidence to the editor and to BBC Complaints, asking that the programme should be dropped or postponed pending investigation, to ensure truth and balance. We received the same answer from the Complaints department and from the editor. They said we should wait to hear the programme before complaining. By then, by now, the damage has been done. Many listeners will believe there is no cause for concern in Balcombe. That is not true.

4)    The programme’s dismissal of the fracking argument was especially damaging at that particular time, exactly one week before the release of Angus Energy’s new planning application was due – for three years of ‘testing’ at Balcombe.

5)    The tone of the presenter was sarcastic and mocking. She spoke of protest and environmental concerns with inexplicable jokiness and scorn. She presented protesters and campaigners as ill informed and violent (neither was true) and as coming largely from outside the village. We have been researching the subject now for eight years, and we are most certainly better informed than the producers of this programme. A great many people from the village protested at the site.

6)   The programme was based on an incorrect assumption that fracking was never planned for Balcombe. That is not true. Oil company Cuadrilla had clearly announced at public meetings and in letters that their intention was to frack.

7)   The ‘we are not fracking at Balcombe’ message came out only in January 2014. In 2014 and 2015, the government, supportive of the oil industry, changed the legal definition of fracking and the definition of ‘conventional’ oil and gas source rocks in planning guidance. Subsequently, many activities that would have been called fracking would not now be called fracking. This ‘Corrections’ programme was about alleged manipulation of vocabulary. They failed to mention those two important cases of manipulation of definitions.

8)    The makers of the programme failed to understand the nature of the planning and permitting process. Planning permission comes in slices. First a company applies to drill, then to test, and then to produce. In Cuadrilla’s case, they applied in the first instance to drill and test. Villagers were clearly told at meetings with Cuadrilla that the test would involve injecting fluids at a pressure just below fracturing point ie ‘not quite fracking’. The fracking would come later, within a new planning phase. Protesters and campaigners knew that. They/we knew that fracking would not take place in 2013. Fracking was for later. We are not stupid. The oil industry increasingly exploits this ‘permission creep’ phenomenon in its eagerness not to admit, yet, that their end game is to frack.

9)   The makers of the programme failed to understand that to stop fracking at the Balcombe site at a later date we knew we needed to protest at drilling stage. Once a company has spent £3.5m on drilling a well, it is hard for council minerals planners to say, ‘No, you can’t test it and you can’t produce from it!’ The protesters/campaigners knew the current planning permission was due to run out at the end of September 2013. The aim of the protests was to delay the drilling so that they would run out of time, and to raise awareness of the hazards of fracking.

10) The programme presents the idea of fracking for oil in the South East as a construct of silly-season journalists and dim-wit protesters. On the contrary, fracking in South East England is a deeply concerning future prospect that has been belittled by this programme.

11) The programme said oil production in the South East would be ‘conventional’ ie in geological terms from permeable rocks. This is a matter of spin and vocabulary manipulation. See below and please ask for further detailed explanation and evidence if required.

12) The programme makes no mention of acidising, an interim stage before fracking the shale – see below and see the attached leaflet

Fracking was in truth always the plan – the detail

Oil and gas prospectors Cuadrilla and their then operator Bolney Resources wrote to the Department for Energy and Climate Change in June 2011 that their plan had ‘always been to drill (a) well(s) (vertical and/or horizontal) targeting the Kimmeridge Shale and to hydraulically fracture stimulate… Without the ability to undertake hydraulic fracture operations, Bolney will not be able to attempt commercial production.’(1) Fracking was at that time subject to a government moratorium following induced earthquakes near Blackpool. The following January 2012, in front of a packed hall in Balcombe, Cuadrilla explained how fracking worked and expressed their intention to frack. See below (2) an article in the Telegraph about this meeting. Thus, when in 2013 protesters from the village and beyond gathered at Balcombe to oppose Cuadrilla’s plans, there was no doubt whatsoever that at some point in the future Cuadrilla intended to frack.

Cuadrilla in fact could do no more than drill during the summer of 2013 because they ran out of time, thanks to the protests. Their planning permission expired at the end of September and they had to leave the site.

Balcombe’s current site operator for Cuadrilla, Angus Energy, own a site on the same geological formation only 14 miles away in Brockham, Surrey. They announced recently that ‘It is extremely unlikely that commercial hydrocarbon flow can be established from the Kimmeridge layer at Brockham’ without fracking (3). (‘Kimmeridge layer’ means the thick layer of shale interspersed with thin layers of muddy limestone.)

The Kimmeridge layer of interbedded shales and limestones under the Weald is the kind of geology that needs to be fracked, cracked open, to release its oil. Once the fractured portion of rock runs dry, another well needs to be drilled, and then another. Looking into the future, the industry would need hundreds of wells across the region to exploit to the full the areas they have licensed. The CEO of one company exploring the Weald has spoken of ‘this kind of geology’ requiring wells ‘back to back’(4).

A new oil field across this beautiful countryside, especially at a time of climate crisis, is no joke.

Earthquakes

For the oil and gas industry it’s a ‘seismic event’ when the earth shakes. For affected communities it’s an ‘earthquake’. Dictionaries define both in the same way. The programme followed the industry line and scoffed at campaigners using the (perfectly correct) term ‘earthquakes’. Their interviewees said that fracking-induced earthquakes are tiny, comparable to a bus passing your house. But earthquakes near Cuadrilla’s Lancashire fracking site peaked at 2.9 on the Richer scale and have damaged houses. The earthquake at Cuadrilla’s earlier Lancashire fracking site in 2011 damaged the well so badly that it had to be shut down. Earthquakes are stronger underground. Damaged wells can release methane and other pollutants into the environment.

Don’t use the F word! Manipulating language – the other side of the argument

By the end of 2013, the public had correctly begun to realise that fracking was a threat to the environment and public health. The word ‘fracking’ had become a PR menace to the oil and gas industry. In the ensuing months and years, ways were found to avoid the F word.

In January 2014, three months after the end of the roadside protests, Cuadrilla declared they had drilled horizontally into a thin muddy limestone layer amidst the thick layer of shale (muddy limestone is much easier to drill through than the jagged shale) and they had found that it ‘didn’t need fracking’. Instead they would dissolve channels through the limestone using acids and other chemicals. This is known in the trade as acidising, and, at a certain pressure, acid fracking (5).

‘Hydraulic fracturing’, in the industry, had always been used to mean fracturing the rock. But in 2015, the government, eager to support the fracking industry, introduced into the Infrastructure Act a new, narrower definition of hydraulic fracturing/fracking based on the amount of water used(6). Under this definition, 89% of the oil wells that have been fracked in the USA would not be considered in the UK to have been fracked(7). The government also inserted an incorrect definition of ‘conventional’ oil-bearing geology into minerals planning guidance(8). Now all limestone was to be considered ‘conventional’ – so the industry could declare all their activities in the thin limestone-rich layers to be ‘conventional’.

Yes, language matters. Communities across the Weald have had eight years to study fracking and acidising with all the politics, antics and semantics that come with them.

Some other errors that also need correcting

a)    The industry writes frac’ing with an apostrophe. They do say frac’ing, and that apostrophe stands for a k.

b)    ‘Shale deposits are mostly in the North. Yes, but there are significant shale deposits in the Weald Basin in the South East. The north has mostly gas, the South East has mostly oil.

c)    Barton Moss in Lancashire had little media coverage, the programme said. How shocking that the BBC, so close to Barton Moss from their new home in Salford, for the most part failed to cover this ‘story’. Yes, there is a southern media bias and yes, Balcombe had the advantage of being on the London to Brighton line and being inhabited by, amongst others, lawyers and professors within easy commute of London. Successful publicity does not equate with spurious story.

d)    The programme said ‘shale gas produces less carbon dioxide than coal or oil. Yes, when it’s burnt. But during production, treatment and transmission enough methane is lost to outweigh that ‘advantage’. In any case, all three must be phased out.

e)    The American flaming tap (or ‘faucet’ as the producer described it, adopting the vocabulary of her American industry-influenced source) had nothing to do with nearby fracked wells, the industry and this programme insists. See http://1trickpony.cachefly.net/gas/pdf/Affirming_Gasland_Sept_2010.pdf for the balancing view of this industry-driven denial.

It is a pity that ‘The Corrections’ failed to do their research, failed to speak to the people of Balcombe, and took no notice of detailed information sent to them by Balcombe residents in plenty of time for this error-ridden programme to be pulled.

More Drilling For The Kimmeridge Oil That Angus Energy Said Could Not Be Produced Without Fracking

On 4th July IGas announced that it is planning to drill two wells at a new site in PEDL (Petroleum Exploration and Development License) 235, just west of Dunsfold, where another driller – UK Oil & Gas (UKOG) is in the process of securing a planning permission to also drill an exploratory well. In addition to the conventional Portland sandstone, the new wells are to target the Kimmeridge rocks – the same strata UKOG and Angus Energy (the third Weald player) are after at various locations around the South East including Brockham, Horse Hill, Balcombe, Broadford Bridge, Arreton on the Isle of Wight and an, as yet unnamed, location targeting the Holmwood prospect in PEDL 143 (which was going to be drilled from Leith Hill until the Environment Minister, Michael Gove, pulled the plug on these plans after nearly 10 years of planning battles).

The IGas announcement comes hot on the heels of news from Angus Energy the week before that their infamous Brockham sidetrack was extremely unlikely to flow commercially without stimulation such as hydraulic fracturing.

Screen Shot 2019-07-10 at 16.37.16.png

In light of the recent persistent assurances of UKOG, Angus and now IGas that the unconventional Kimmeridge reservoir can be produced via conventional methods (or conventional wells), this is an astonishing admission, which vindicates what we have been saying all along – that the Kimmeridge will need fracking (whether with water or with acid) to flow commercially. Our warnings have been based on the available geological and extraction data from similar reservoirs elsewhere in the world, and on the expert opinion of David Smythe, Emeritus Professor of Geophysics at the University of Glasgow.

Angus Energy’s statement agrees with what Cuadrilla (who since handed over the operatorship to Angus) said about producing the Kimmeridge in Balcombe in 2011; their letter to the Department of Energy and Climate Change (the predecessor to today’s Oil and Gas Authority) reads that the company would “need to rely, to a significant degree, on being able to undertake hydraulic fracture stimulation(s) of this unconventional reservoir.” Some years later, the Balcombe Kimmeridge is yet to be successfully tested…

Screen Shot 2019-07-10 at 16.57.10.png

At Broadford Bridge, where UKOG tested the Kimmeridge in late 2017/early 2018, it concluded that the rock “appears to be unproductive due to low reservoir permeability” and that new completion and “other reservoir stimulation techniques” would be considered on future wells (see here and here).

Horse Hill, also operated by UKOG, is the only site where, according to the company, the Kimmeridge has been flowing oil (although its development has been put on hold until after the start of full-scale Portland production..). Detailed analysis shows that the Horse Hill exploratory well was drilled into a fault, presumably to help the flow. And UKOG has been less than clear about the methods it is using on this well. In 2015 Stephen Sanderson, the firm’s chief executive and executive chairman, was openly talking about stimulation; while a 2016 paper published by EY – the global consultancy – and commissioned by UKOG, said that the Kimmeridge will likely require stimulation with acid to flow to surface at commercial rates (despite the apparently naturally occurring fractures). But since then UKOG has revised its position, claiming that only a weak acid wash should be used (while inadvertently confirming they did more than that at Broadford Bridge, but that it didn’t work).

In addition to this confusion we are also dealing with muddled definitions in the UK legal and regulatory framework about what fracking actually is, and whether it includes acid stimulation (we will explore this in another piece). Whatever the definition, the Kimmeridge rock is tight and any production expected to decline rapidly, and the proliferation of wells we are seeing looks like the beginning of what Mr Sanderson described in early 2016 in his famous statement: “this type of oil deposit very much depends on being able to drill your wells almost back-to-back so it becomes very much like an industrialised process”. You can watch see the exact excerpt here:

Who knows, maybe none of the above matters anyway? If, as Angus seem to also surmise (somewhat contradicting the above conclusion), the Kimmeridge at Brockham is not mature and doesn’t have enough recoverable oil, then no amount of fracking, acidising or other extreme methods will make the Kimmeridge wells commercial.

Breaking Brockham News, Earthquakes & Horse Hill Update

Brockham News!

We have some very important news to share: last Friday Angus Energy announced that “it is extremely unlikely that commercial hydrocarbon flow can be established from the Kimmeridge layer at Brockham” and that they have entered into discussions to sell their 65% interest in the Brockham license to an unnamed third party. The news slashed Angus’s share price by 60% in a single day. It came as a huge surprise not only to us, but also the investor community, who were expecting Angus to continue with the well tests commencing in the week of 17 June, as per the published regulatory news release two weeks prior.

Angus also clarified that the Kimmeridge would not flow “on any conventional approach” and that they ruled out the use of stimulation techniques including hydraulic fracturing (because Angus Energy is a non-fracking company, i.e. they don’t have the expertise or the financial resources to frack successfully), in effect confirming what Professor David Smythe, BOW and others have been saying all along – that it will not be possible to commercially produce from the Kimmeridge without hydraulic fracturing or acid stimulation.

This means that there’s still a danger that Angus will sell the Brockham operatorship and their 65% interest in the license to a company who will want to frack. We will be watching developments closely.

In the meantime, we’d like to thank all those who have been keeping a watchful eye on the actions of Angus Energy at Brockham, and helping to maintain pressure on the regulators to make sure the site is monitored closely. We can say with certainly that the scrutiny by regular people made a difference.

Earthquakes Meeting

Over 150 people, including a number of local councillors, attended a public meeting on earthquakes and unconventional drilling in the Weald Basin we held last month at Beare Green Village Hall.

David K Smythe, Emeritus Professor of Geophysics in the University of Glasgow, delivered the main talk, covering the history of oil & gas exploration in the Weald between 1960-90 versus the current phase led by penny-share companies of questionable competence and integrity, the reasons why he supports the Edinburgh University thesis that the Newdigate earthquakes are induced by activity at the Horse Hill site, and recommendations for local residents as well as their elected representatives.

To watch the recording/ see slides, go here.

On a related note, we created a page dedicated to the Newdigate earthquakes and a page tracking related news, where you can catch up on what happened so far.

More on Horse Hill

The meeting to decide on the significant expansion proposals at Horse Hill has been postponed yet again, and it is currently planned for 11th September 2019. This application received over 1,000 objections. Although the official consultation has now ended, you can still comment to the council (here are some helpful links).

And more..

We also want to share this recent story about a breach of blowout preventer safety laws at Horse Hill. Blowouts pose risk to life for well workers, and can have profound consequences for the environment and wildlife. Please share this story with anyone concerned.

Over 150 people, including a number of local councillors, attended a public meeting on earthquakes and unconventional drilling in the Weald Basin held last Saturday (18 May) evening at Beare Green Village Hall. The gathering was organised by Brockham Oil Watch and chaired by Max Rosenberg, Chairman of CPRE Mole Valley.

David K Smythe, Emeritus Professor of Geophysics in the University of Glasgow, delivered the main talk, covering the history of oil & gas exploration in the Weald between 1960-90 versus the current phase led by penny-share companies of questionable competence and integrity, the reasons why he supports the Edinburgh University thesis that the Newdigate earthquakes are induced by activity at the Horse Hill site, and recommendations for local residents as well as their elected representatives.

Professor Smythe criticised the authorities and the operator for withholding crucial work programme logs from the Horse Hill site, and advised that the precautionary principle should apply halting operations while more research is undertaken. He called for residents to collate systematic data on earthquake damage.

Ada Zaffina of BOW gave a brief overview of the loophole in the UK regulatory system with regards to acid stimulation, potentially allowing these stimulation treatments to take place under the guise of acid wash. The presentations were followed by a lively Q&A time stretching the duration of the meeting to two hours.

We are very pleased with the turnout, especially since we were competing with the Eurovision Final and the FA Cup Final. The level and detail of questions and comments from very astute locals and councillors shows deep concern about the earthquakes and the possibility of larger magnitude tremors. We hope that this will embolden more people to speak up about their concerns and demand clear action.

With the recently released FOI documents showing that a well intervention on HH-1 was planned for early April 2018, UKOG’s fundamental argument that the earthquakes started before they did any work on this well is put into question. There are striking coincidences between the timings of operations (at Horse Hill) over the last year or so and ongoing tremors, and those are much stronger than the 0.5ML that halts operations on fracking sites up North. Many people in Newdigate live in constant anxiety over the prospect of another, possibly stronger earthquake. We shouldn’t be searching for a smoking gun that Horse Hill is inducing the tremors, we should be asking that operations be stopped until we are absolutely sure that they are not causing them.

We would also like to thank everyone involved in the organisation and promotion. This event is a great example of worried communities coming together.
