RE:RE: "300m thick cement plug"Generally, bridge plugs are not industry standard, nor regulator approved, isolation over a hydrocarbon bearing zone for abandonment purposes. These are exploration wells used for G&G purposes, so production was never intended, and likely designed to be abandoned after the information from the well was gathered. Either that, or there were hole troubles, they are isolating the zone and planning on kicking off... but I highly doubt that.
