What is wrong with them?
Short answer: Nothing.
Long answer: HE1's licences (and in particular the ones they have retained) are on flat, easily accessible land, in the middle of the rift valley. This means that you can easily do cost-effective geophysical & geochemical surveying, such as with seismic trucks, soil measurements, multispectral satellite imagery, and various electromagnetic techniques. The prospects are structurally defined, large and relatively cheap to drill.
Compare that with Noble, where the licences are either under water or on steep, rocky slopes. They justify this by claiming that they are targeting prospects that are laterally closed by basement, which gives a 'better' seal. HE1's seals look just fine to me. Anyway, the type of prospect they are targeting is likely to be smaller in area, has less exposure to migrating Helium (it can only come in from one side, not all around), are unlikely to be stacked plays, and will cost a lot more to drill. So Noble have to be pretty sure that each drill is going to hit something worthwhile, otherwise they are going to run out of cash pretty quickly.
How do you do that? You can't use several different exploration techniques and cross-correlate the results as HE1 have done - you can't drive a seismic truck underwater or on a 45° slope, you can't do EM underwater, nor utilise MSSI. So you have to rely on just one technique - old fashioned 3D seismic. Yes, it's a lot better than 2D, particularly if you have small prospects, but it's hideously expensive. Things can and still do go wrong when exploration relies exclusively on one technique.
I'll leave it to you to decide which company is following the more cost-effective strategy, I have already made my decision.
