I have a feeling they are talking about nitrogen pumping prior to drilling out the obstruction. I.E. As a way of explaining the need for a drill rig. I say this because it says it's now unobstructed and ready to reinitiate flow test. Either way it's a clunky piece of writing.
Overall overall, yes, it seems positive as we are back to testing.
One concern is that the horizontal might be prone to collapse. This, however is more of a concern during the testing phase. During multi well development phase you'd expect them to have a clean up rig on hand to deal with such issues as they come up?
