  1. It’ll be interesting to see how onshore production changes to cash in on the huge spike in world prices, particularly Wytch Farm as they have the overwhelming share of UK onshore supply. With only 1.73% of UK oil production, I wonder how it compares with UK consumption? Hard to imagine it having any impact on overall energy pricing.

  2. Don’t think Wytch Farm will change much, Mike. It is a field that used to produce over 100k barrels per day and is now declining. There may be a few tweaks that will squeeze a few more drops, but the continuing decline is certain.

    The other on shore sites, where there are opportunities for increasing weekly output, will probably push ahead for that but there the potential volumes are small compared to Wytch Farm.

    What will have an impact on pricing is if a windfall levy is imposed in the N.Sea. What an absolutely crazy idea. All that would happen is that oil and gas prices would rise further. World demand is greater than supply hence increased prices. Encourage less oil and gas to be produced in the N.Sea and guess what? Prices would go higher still, and investment into renewables would be reduced! OPEC producers will not be inclined to produce more. They are busy making up for losses in 2020 and will control supplies to keep prices high.

    Pray for warm weather around the world over the next 10 months if you want energy prices to drop. Ironic really.

  3. Right let’s crack on with fracking’!
    You cannot make an omelette without cracking a few eggs!,
    Energy security is real, energy poverty is real! If we need tax dollars and something to trade, and something to create energy gas is the cleanest and greenest energy there is, without looking at the carbon footprint of designing, manufacturing, building, shipping and commissioning thousands of floating wi d turbines!! That uses a lot! Of Energy!!

    Yes there is inconvenience with fracking, but soap box aside it’s either that or the lights go out and the Russians, Norwegians and Qatari’s would be delighted to get hold of your cash.., #homeproducedgreenerenergy
