Yeah, thanks, Andy. Good morning Bob. I think the first point to note is that we’re still very, very early on in this exploration campaign and to open this frontier base enough. This is 2,100 Gulf Mexico block, so it's a very big area. But as we drill wells, we now about six in the ground. We’re beginning to slowly understand the area and the first point I would make is to your point to be honest, is that northern Senegal clearly is a giant gas resource area for us. We've now made, you include Tortue three discoveries, out of three in Northern Senegal in the two blocks. And Requin Tigre, which is a 60 Tcf prospect that's been further derisked by Yakaar-1 significantly, remains undrilled. So, a giant gas resource in that area, but to your point, we are focused on funding oil and liquids. And that's one of the reasons from a play standpoint that we’re moving further north. I think we started to understand the petroleum system in good detail in Northern Senegal. We still have very little understanding in northern Mauritania where we've got limited number of penetrations. So, Hippocampe it’s located in the northern part of Block C8, it’s actually 225 kilometers away from Yakaar. It gives you a sense of the scale of the space. And if you’re putting a well down there it's going to help us better understand the presence of source rocks, the quality, their maturity, their timing of migration et cetera, which will start to allow it to get a really good handle on how the petroleum system is working up there and more important and as importantly. The nature of the contribution from the two shallow resource rocks, the Albian and the CT, which we haven't yet tested because in the wells that we drilled, the CT and Albian has always been immature or at best very marginal mature for the Albian. So, that's one reason, this mixing of the shall hydrocarbons with the deeper hydrocarbons we think is going to give us a good chance of finding liquids to the north. Deeper count though won’t be definitive, it's one of a number of prospects in northern Mauritania. We’ve previously talked about Lamantin been our best chance for oil. That area in general northern C8, C6, C12, we believe it's got a good opportunity to find liquids and oil and the explorations program is going to shift to that area for the first test we believe would hit account at this point.
