RE: Reservoir Quality25 Jan 2023 10:48
TF,
Why look at the deeper well first? We Art is pretty confident that this is a big discovery. So picking the deepest well and showing that it flows proves oil down to this point in the structure. Therefore maximum acreage covered and anything updip from that towards the top of the structure should be derisked as the structure has live oil down to this point. What folks aren't picking up on, and something that Art covered in the recent interview is the wells weren't drilled ideally. They were drilled with water based mud, therefore they've had the degradation issue close to the wellbore, oil degraded to sludge, That and the reservoir quality being good (naturally fractured too from last interview) meant that the cement from the casing also penetrated the reservoir. So reservoir quality is high. But regardless of these issues close to the wellbore it still manages to flow live oil in increasing volumes as the oil drill fluid and cement clears up. That just shows how willing this Frontier sand is to flow to surface.
Now imagine that new wells are drilled with oil based drill mud and not water based, a well that is drilled with the correct mud weight etc so less fluid and cement enters the reservoir and then they test that! The fact that the reservoir is naturally fractured means that some of the future horizontal wells may not need frac, lowering costs and potentially increasing the recoverable oil. Monday's news was highly significant to derisking the Frontier 1 at CCU and Fed deeps. Live oil is there and flowing through less than ideal conditions due to how the old wells were drilled. Reservoir quality is there with the mention of drilling mud and cement easily entering the reservoir and Art talking about the fractures. Pressure is there and also the Fed Deeps discovery well, gassy oil meaning there's a natural pressure due to the GOR. People just need to listen to that last interview on the Frontier 1. The clues are all there.
