The big elephant in the room is why weren't they able to get nitrogen to flow to surface. That implies that either the coil string itself was blocked up, or something blocked the annuls between the coil and the surface casing which is where returns would flow up the well. There should be more clarity around what the possible reason for no flow to surface was or why they're happy to just leave it as is and re-run the completions. They've obviously made the decision to move the Coil unit off location and continue with running the completion - so lets hope that's a good sign, and not a gamble.
