In their Community Engagement Brochure and planning application of 2019, UKOG state that they don’t want to “Industrialise Surrey or Sussex”.
The relevant document can be seen here on Surrey CC’s website – pages 20 and 26:
The nature of “Tight Oil” means that it doesn’t just flow from the ground under its own pressure. This means it must be teased out, and much like sucking water from a sponge, teasing from one spot won’t get it all out. There must be many points of entry – many well pads.
Stephen Sanderson, CEO of UKOG explains in the video below: “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”.
The video was compiled in 2016 and is provided by the Frack-off.org website.
Note that that UKOG have stated that they don’t want or need to do any fracking. The process they propose in the 2019 planning application uses ‘new techniques’.
In 2016 UKOG was full of hope for back to back drilling but things have not gone according to plan for Sanderson. It has run into trouble at its other sites in the Weald (https://drillordrop.com/2019/07/03/onshore-licence-moves-to-production-without-drilling-a-successful-well/ ). UKOG now says “because of the chemical composition of the rocks, the acidisation process can have a significantly detrimental effect on the ability of oil and gas to flow into the well”. As a result it seems to have ruled out “matrix acidisation” as its preferred stimulation technique and it is now looking to its proposed site at Dunsfold to experiment with ‘new techniques’ to see if it can find a solution. In other words, Dunsfold is going to be a UKOG guinea pig.
So how will UKOG stimulate the oil at Dunsfold to get it out? That is a very good question. The company has also said in the past that it won’t use ‘hydraulic fracking’ (plus we think it doesn’t have the resource as fracking is for the big boys) but with these ruled out Drill or Drop (the independent online newspaper which reports on the oil and gas industry) suggests the choice could come down to ‘acid fracturing’ or a new technique known as ‘fishbones’ https://www.fishbones.as/ both of which still involve stimulation using acid.
Meanwhile, in another part of the Weald over at Brockham in Sussex, Angus Energy, who control the extraction licence for that sector, have just announced with are withdrawing from the site having failed to extract oil commercially. They said publicly in June 2019 that to get oil out commercially Brockham needs (yes, you guessed), Hydraulic Fracturing i.e FRACKING – which coincidentally is exactly what Conoco said would be needed at Balcombe back in 2010.
