The UK shale gas industry has upgraded production estimates by more than 70% following early results from two sites.

In a report published this morning, the industry organisation, UK Onshore Oil and Gas (UKOOG), said it had increased its central estimate of productivity to 5.5 billion cubic feet (bcf) per lateral well.

Based on this figure, UKOOG predicted that annual UK shale gas production could peak in the early 2030s at 1,400 bcf. This would be enough, it said, to supply 35 million homes, more than the UK total, and eliminate the need for net gas imports.

The figure is based on estimates from flow tests at Cuadrilla’s Preston New Road site, where just 5% of the well was fracked as planned, and what UKOOG called “encouraging” shale drilling in Nottinghamshire.

Assumptions

The peak also relies on assumptions that are likely to alarm opponents of the industry:

  • 100 pads, each with 40 lateral wells
  • Unhindered flow tests
  • Drilling and fracking 4-6 lateral wells per pad per year for seven years
  • Construction of 10 new pads each year for nine years

DrillOrDrop could not find a pad with 40 laterals anywhere in the world so we asked for an example. UKOOG said “some US operators were working with 20-40 wells per pad”. It also mentioned Encana’s mega pad in Texas with capacity for 64 wells, which the company reportedly compared to a “military occupation”. UKOOG also said UK shales were thicker than those in the US and UK land use controls tighter so multi-lateral pads would be more prevalent here.

We also asked whether “unhindered flow tests” meant that the “traffic light system” regulations on induced seismicity would be abandoned.

The rules currently require fracking to pause for at least 18 hours if it induces earth tremors measuring 0.5ML (local magnitude) or more. Cuadrilla had complained that the traffic light system had restricted its flow tests and could make shale gas commercially unviable.

UKOOG said its report assumed there would be a review of the traffic light system but so far it has not put a figure on what it thinks the threshold should be for stopping work. A spokesperson said:

“Cuadrilla estimated the recovery of their well with all stages fractured as planned.”

So far, UK shale gas companies have drilled at just three sites: Preston New Road and the Nottinghamshire sites of Springs Road, Misson, and Tinker Lane. Fracking has paused at Preston New Road. The Tinker Lane well is to be plugged and abandoned after failing to encounter the Bowland Shale. Drilling the vertical well at Misson has not yet reached its target depth, though the operator, IGas, said today it had encountered more than 250m of shale. Planning permission is in place at two other sites: Marsh Lane in Derbyshire and Harthill in south Yorkshire.

Carbon savings and balance of payments

UKOOG also said a domestic shale gas industry would save 80 million tonnes of lifecycle carbon dioxide by 2035.

The calculation relied on the conclusion that liquified natural gas had a larger carbon footprint than UK shale gas (2013 Mackay and Stone report for the UK government). This conclusion has since been challenged and was a key argument in a successful legal challenge to the government last week.

UKOOG assumed UK shale gas would displace imported liquified natural gas (LNG). This LNG would, in turn, was assumed to displace coal elsewhere in the world. DrillOrDrop asked UKOOG what the assumed mechanism would be for not producing or burning coal. UKOOG said the savings could not be guaranteed because “it cannot be mandated that displacing LNG will always replace coal in power generation”. It added that the UK will import gas from non-LNG sources as well as LNG.

If achievable, carbon benefits from UK shale gas production on the UKOOG scenario would probably come too late for new houses in the UK. The Committee on Climate Change recommended last month that no new homes should be connected to the gas grid from 2025.

UKOOG responded that gas remained a vital source of energy for the UK in all scenarios, including those compatible with UK emission reduction targets. The organisation said:

“Nothing in the CCC’s recommendations for new homes changes this vital point.  Indeed, 85% of home are connected to the grid.”

Balance of payments benefits

Based on the production assumptions, UKOOG said the elimination of net gas imports would improve the balance of payments by about £8 billion a year. This is the same figure as the estimate in a report in 2013 by the Institute of Directors that assumed peak gas production at 1,100 bcf.

UKOOG said it had not calculated a figure for tax flows because it did not have data on the costs of production. But it said the industry had already invested £400m-£500m and it endorsed a 2014 estimate by EY that the industry would spend £33bn over two decades in the supply chain.

A single pad of 40 laterals would provide £13.5m in community benefits and £27m in business rates, assuming a 25-year lifetime, UKOOG added.

“Growing in strength”

UKOOG’s chief executive, Ken Cronin

UKOOG’s chief executive, Ken Cronin, said:

“This is a very significant upgrade to previous estimates. The industry to date has invested between £400m and £500m in exploring for shale gas in the UK, creating local jobs and supply chain opportunities. The UK spends £7bn at present per year on importing gas into this country, generating next to nothing by way of UK benefits, leaving us less secure and creating a greater environmental impact as gas is shipped and piped in across oceans and continents.

“Last year the UK’s LNG imports grew by 20%, with Russian LNG showing the largest increase at nearly 20 times the 2017 figures – the equivalent to supplying 1.6 million UK homes. Given these new projections, it now makes absolutely no sense to ignore our huge resource of homegrown gas.

“I am delighted at the way the industry has stepped up in delivering on the potential highlighted in 2013, and in fact there is a bigger opportunity. I have also been impressed at how the industry has worked together to improve performance at each new site. The reduction in drilling times has shown that the commercial prospects for the industry are growing in strength.”

Reaction – shale gas opponents

Dr Doug Parr, chief scientist, Greenpeace

“UKOOG’s ‘updated’ figures are six years out of date. They are still using a 2013 figure from the Institute of Directors, forecasting that the UK fracking industry would drill 4,000 wells, at a rate of 400 a year.

“This has been thoroughly debunked by the government in a Cabinet Office report, and by Dan Lewis, senior adviser at the IoD, who told Unearthed last year that ‘The 2013 projection that, at peak, the UK’s drilling schedule could see 400 new laterals installed hasn’t come to pass, for a variety of reasons’.

“And it’s been debunked by reality. Greenpeace are aware of two fracked wells in the UK, one at Preston New Road, currently inactive due to earthquakes, and one at Preese Hall, abandoned due to earthquake damage. We may have missed one, maybe even two, but not 400 a year.”

Tony Bosworth, Friends of the Earth

“The shale gas industry appears to have strapped on the rosiest of rose-tinted glasses to look at the future. These new figures are mainly based on extrapolation from just one partly-fracked well.

“This is the latest industry attempt to push for more government concessions to make fracking easier. Ministers mustn’t water down the rules by allowing oil and gas firms to drill without planning permission, or cave into their demands to be allowed to trigger bigger earthquakes before having to down tools.”

Steve Mason, Frack Free United

“Here we have an example of a trade body talking up its own industry for the benefit of its members, as any good well paid trade body would. Claire Perry confirmed again last week in Westminster, there has only ever been 2 fracks in the UK, but somehow UKOOG seem to have built a whole scenario around one well that was only 5% fracked and had to shut down because of the higher risk of earthquakes.

“But it is nice to have confirmation that the industry is planning thousands of wells across the UK as we have been saying for years. I’d hate to be living anywhere near any of these ‘Super pads’ they are now talking about with 24/7 drilling, fracking and industrialised operations for years and years.

“What I do find interesting is that these figures came out just a few days after frackers received more bad news as the government lost its battle in the high court, concluding that the National Planning Policy Framework paragraph on support for shale gas exploration was unlawful. Coincidentally, it also called into question the very same Mackay and Stone climate study which UKOOG have referenced in this report to back up its justification to frack across the UK.

“Let’s be grown-ups about this. Does anyone really believe that the fracking companies will just stop at a few thousand wells?  The companies have shareholders and profit to look after, I seriously doubt they are likely to have a crisis of conscience and want to stop fracking in the 2030’s . The UK should be cutting back its fossil fuel usage, not adding to the global supply. We certainly should not be locking ourselves into a new fossil fuel dependency for the next 50 years.”

Peter Allen, Frack Free Ryedale

“This is really dangerous stuff. “Not just because their figures should worry us but because parts of it are blatantly untrue.

“For instance, according to DUKES imports of LNG – far from being such a large part of our gas – supply fell by 30% in 2017 (they fell 40% from Qatar) and there are many more examples here that are false.

“The problem is that many people will believe it and for those who have read Claire Perry’s response to a question on acidisation in Parliament last week we can have no faith that the government actually know what is going on.

“This is headline grabbing stuff that they hope will strengthen public opinion in their favour regardless of a total lack of truth.”

Dr Tim Thornton, retired Ryedale GP and anti-fracking campaigner

“UKOOG assumes up to 40 laterals off one well pad, which could result in the community being exposed to heavy traffic increases, air pollution, night-time noise that exceeds the limits councils set (Kirby Misperton and Preston New Road) uncontrolled releases of gases (West Newton and Preston New Road) and seismic events/earthquakes (Preese Hall and Preston New Road) for what the industry refer to as a ‘short time’. This short time is likely to be at least three months per lateral, amounting to 120 months or 10 years.

“With exposure to the concentration of wells and the high activities of drilling and fracking, communities may expect to have similar health effects that others have experienced around the world. This includes pre-term-babies, complicated pregnancies, asthma attacks, heart attacks, stroke, migraines, depression, and a multitude of social and financial impacts.

“UKOOG seems happy to be producing a novel fossil fuel in the UK to reduce the cost of imported fuel. Perhaps we should all be looking at reducing fossil fuel use in UK and investing in solar, wind, heat pumps and research into wave, tide and Electric Vehicles.  UKOOG argues that CO2 emissions may be lower for shale gas than LNG but ignores the rise in global emissions of methane – caused by fracking – which is a far stronger greenhouse gas. Already we have seen cold venting of methane at West Newton and Preston New Road and applications for flaring rather than using the fracked gas.

“UKOOG represents the fossils of our national thinking. We should not be tempted into their magical predictions or the number of homes linked to the gas grid. If we respect our children and grandchildren then gas, oil and coal should all be consigned to the history books.”

Dr Simon Sweeney, University of York

“With climate breakdown already happening (record February temperatures in the UK, rain in February on Greenland, violent storms in southern Europe and the USA) it is astonishing that corporate behemoths have the gall to push ahead with more fossil fuel extraction.

“Clearly anti-fracking campaigners were right: UKOOG wants to industrialise the rural landscape and degrade communities on a massive scale.

“The High Court ruled last week that government support for fracking is illegal because it failed to take climate change into account.

“What will it take to persuade the government to support local, national and international efforts to switch entirely to renewable energy and boost conservation?

“We need a government that will unequivocally support multilateral agencies in combating an existential threat to life on earth.

“The UKOOG estimates are yet another warning sign of what is to come without sustained public protest.  And not just by children.”

Reaction – shale gas supporters

Francis Egan, chief executive, Cuadrilla

“We should not underestimate what is at stake here for the UK. Securing our domestic gas supply is only one part of this equation. Consider also the amount of tax revenue this industry could create and what improvements that could support in society. Consider also the alternative. Just last week, latest figures from Government revealed our reliance on LNG imported from Russia had risen dramatically in 2018 and now makes up about 20 per cent of all imported LNG into this country. This is an increase of about 20 per cent compared to 2017.

“Yet here we have a rich resource of high quality natural shale gas which would flow directly into the local grid with minimal treatment with each site providing enough gas for half a million homes. The forecast is clear that 60 sites could reduce our £7bn spend and reliance on imports by 50 per cent. It would boost our economy and ensure we have enough energy to heat our homes and food for many, many years to come.

“Cuadrilla has proved it is there and that we can extract it safely and in an environmentally responsible way. We’re back on site and we’re getting ready to make these estimations a reality. It is now imperative that people understand that they have nothing to fear from fracking and actually a huge amount to gain.”

Lee Petts, Lancashire for Shale

“These new forecasts suggest that Lancashire really is sitting on a world-class shale deposit, and that it has incredible potential to help meet a significant proportion of the UK’s gas demand whilst cutting back on imports that come at a higher financial and environmental cost.

“With sensible forecasts showing that we’ll still be using considerable quantities of gas to heat our homes in 2050 and beyond, it makes sense to use more of our own if we can, creating jobs and prosperity along the way, rather than increasingly relying on gas from other countries.

“Today’s delivery of equipment is a welcome sign that Cuadrilla remains committed to advancing its shale gas exploration plans in Lancashire. There’s a lot at stake here, given what we now know about shale’s real potential, and so it’s good to see Cuadrilla continuing it’s vital work.”

Key figures

UKOOG 2019: central production scenario of 5.5bcf per lateral. Total annual UK peak production of almost 1,400bcf in 2030s, eliminating net gas imports.

Institute of Directors 2013: central production scenario of 3.2bcf per lateral. Total annual UK peak production of 1,100bcf, reducing net gas imports in 2030 from 76% to 37%.

  1. And after the 4000 wells are in place, we’ll get this:
    https://www.resilience.org/stories/2019-03-07/new-warnings-on-plastics-health-risks-as-fracking-industry-promotes-new-plastics-belt-build-out/

    For all the fuss about stopping the use of plastic, we will never be rid of the stuff until we stop extracting fossil fuels, as it is a byproduct of the industry. If we hadn’t had all that plastic that is now polluting the entire ecosystem, there’d be literally mountains of black gunk sitting outside of every refinery on earth:

    • What?, this makes no sense.
      The contribution of Fossil Fuels is vast, Hygiene & Accessories:
      Deodorant
      Clothes & Shoes
      Lipstick & Mascara
      Sun Glasses & Eyeglasses

      Automotive:
      Fan Belts
      Motor Oil
      Gasoline
      Tires

      At Home:
      Refrigerators
      Toilet Seats
      Detergents
      Dishwashers
      Telephones

      So you were saying???

      • What ? So stop wearing makeup ? Or use natural products like the native American Indians . I do my own washing up and have a wooden toilet seat , maybe stop changing your phone every 6 months , just wear sunglasses from a charity shop when you are getting some pre loved clothes that are much better than designer labels , maybe stop having pointless fashion shows where exceptionally skinny women wear things that nobody would be seen dead in , maybe just give enough of a 5h1t to think that we all don’t need half of this stuff and that what we do can make a difference . You obviously like your gadgets , I bet you have cupboards full of plastic rubbish that you used once. I could go on but I probably lost you after the first bit.

        • So, Jono, you have a wooden toilet seat but a plastic keyboard.

          I wonder which produces more 5h1t, in your terminology?

      • Eli-Goth, I wonder what the hell we did before oil?

        Were we all naked? No, you all cry!

        A prize for anyone who CANNOT show an alternative to fossil fuel to make the above products…

        • Yes we all cry, Passepartout. Then, we started to move out of the warmer African areas and had to cover ourselves up. Then we started to use fossil fuels to keep warm, and then we progressed to cease chopping down trees and started using stuff from underground to keep ourselves warm.

    • Mark Bevis

      That link refers to shale oil fracking, and the fracking of gas high in NGLs. Then the resultant plastics industry, an industry they need to absorb the various heavy ends of their ( unwanted ) gas.

      UK gas is primarily methane it seems, so is not suitable for plastic industry feedstock as it is light in NGLs.

      So even if 100 well pads turned up, the UK plastics industry would still need to import NGLs, or just move to America.

      The issue of plastic production remains although the key issue seems to be its disposal.

      • “Really?: I suggest you keep your implied sarcasm to yourself. My comment was posted BEFORE publicity was given to the news you mention. Whether it really amounts to anything is entirely another matter.

        • Really? Your comment was alongside a time. So was the information provided by IGAS. So was the information provided by Egdon. So was the “heads up” by Sky, which was even before the RNS. And much earlier, INEOS had suggested such news would drop-hence some had been looking out for it.

          So sorry to contradict, but the clock doesn’t support your statement. I find it hard to see that as sarcasm.

          But, yes, it may not amount to anything-although looking at the flurry of activity amongst the antis there seems to be a lot of concern it may. Q2 and we should know more, although the reaction will not necessarily reflect whatever it shows.

  2. This smacks of desperation by an industry which knows it is in serious trouble. Roll out the spin doctors. They can’t even get the gas out of the ground safely or economically and they know it.

  3. Assumptions and estimates and a load of porky pies. Just stick to reading Hans Christian Andersen Ken and stop making up your own fairy tales.

  4. So figures based on 5% of Cuadrilla’s well that cant be completed within the agreed regulation is the basis for this outrageous guestimate ?

  5. Oh dear!
    Desperate words from a desperate industry!
    It cannot operate a fraction of just one well without falling foul of the earthquake safety thresholds!
    Only in fantasy land will this threshold be raised!
    Their industry is finished!

  6. So, Greenpeas reckons data from 2013 is outdated, but 2013 data (speculation) for economics is routinely quoted as fact.
