So I'll take the second question around pricing, Murray will take the volume question and help me if we got anything, right. So on oil prices, it's so we have updated our oil prices, as we do every year, we update them last year. And basically from our existing assumption, the near term prices drifted up a little bit. And the long-term prices drifted down a little bit such that on average, throughout the period, they were pretty much the same. Our oil price assumption for 2030 is $60 real based on the 2020 baseline, which is $71, which is roughly what it was in 2021. Now, the question, of course, that you ask is, well, what if the transition goes faster if it does this or that? What I think is interesting, Martijn, about the transition question is that an accelerating transition doesn't always lead to a lower oil price. It depends on investment patterns, not just demand. So you could argue, you could see a world where because of lack of investment, even though the energy transition is accelerating, oil prices are much, much higher, which is sort of counterintuitive to how some people would think about it. I think, because the kind of general sense is that accelerating transition means lower prices. That need not be the case, because as we know, it reply, it relies not just on a demand side of the equation, but also a supply side. And of course, what people sometimes forget is that oil fields decline, and therefore they will -- they need investment. So that's a long story short to say. The energy transition could actually result in higher prices, even if it's accelerating, as well as obviously result in lower prices. Our job on an annual basis is to put forward our best view, knowing that it's probably not right. I think I can say that, because that's true, probably not right. But it is our best estimate. And our best estimate is $60 real and we think that balances up all the things that we know about in the world. If oil prices are lower, our businesses resilient to that. We've taken out cost, we're at $6 per barrel production costs so. We've got the tightest highest margin portfolio that we can, and that $9 billion to $10 billion won't be 20% of overall EBITDA it will be 50% or something higher, and vice versa. So there's no simple answer to your question, I'm afraid, but that's how we would think about it. And then on the upstream volumes and underlying production flat.
