2c OBL is better leverage to the Laurel than REY, not BRU though. At 2c it's close to equalizing out on the Laurel (and already obliterated for conv oil). I'm basing my figures on an apples for apples comparison of OBL post farm out for a drill or two at around 25% of Derby. Buru has literally 17.6 times the areal extent of the laurel that OBL does on a post farm out basis (which is the only way to compare it unless you want to pretend Mitsubishi hasn't farmed into Buru's area).
Bear in mind I'm taking the Derby coastline out, the town itself, the airbase and the water from Derby measurements given none of those are going to have drills in them. For the sake of argument I'm leaving the town aquifier in although I doubt the locals will want to drill through that either.

Also in both cases BRU and REY have conventional oil prospectivity, so much so that people don't even talk about REY's Laurel at all. Think about that for a moment. REY's Laurel is basically the same size as OBL's and no one cares about it or even mentions it. Everything is about the Ungani trend, the trend, the hole of the donut, oil, oil which is probably as it should be given the ease of commercialisation in comparison. So it's not an apples to apples comparison either if you're going to be a LT holder.
What I'm talking about as a leverage play is more to buy now at 0.5-0.6c and flip some mid year when Buru is testing and flip some more on results maybe leave some in for other trading points like a farm out, seismic results etc.
