CNE's impairment wasn't only based on lower production in 2018. What they did say was that they have the time/opportunity to do well tests on their own, and based on the water-cut that they were seeing, they expect production rates to be lower by 20% compared to the FDP. There was no change to the longevity of the reservoir itself, but they did classify it as an 'accounting write-down'. Here's some detail from their March call.

Yes, okay. Essentially, we’ll comment in two ways as – why we are taking the reserves downgrade and basically why we’re doing it now. So firstly, a little bit about so obviously heavy oil was quite different from light oil. And water was always expected in this field and in every well quite early on. So that, we should have that in our minds and mainly because it’s a viscous oil field. So the displacement of oil by water was always going to be less efficient than in a light oil field. So it’s very similar in that respect to Capitaine.
The facility has been built to handle, process, reinject the produced water. However, what is clear today is that the displacement of oil by water is not as efficient as we had originally expected in the field development plant, so consequently we are producing a level of water today which is higher than what we had in the FDP. Now so why have we actually decided to take a downgrade now? Is we said back in September, that we were going to carry out a program of reservoir surveillance and well testing.
The wells, both the production wells and the injection wells, are performing very strongly. So we’ve got continuous production from the whole length of the lateral – the horizontal section. We’ve got very good injection across the horizontal injectors. It’s a line drive. And that’s all performing really well. We’ve produced a meaningful volume of oil. So we produced 15.5 million barrels of oil from this field at the year-end 2018.
And we’ve updated and history matched. Our reservoir model was a generated new production forecast from them. And we know that we’re producing. Even if you take out the FPSO performance, we know we’re producing at an oil rate about 20% lower, below the FDP. So if we had readjusted for the poorer performance than we expected on the FPSO the surface or above ground, as you’ve described it, we might have produced 40,000 barrels of oil a day. That’s 20% lower than the target oil volume associated with the reserves in the FDP. And when we put all of those factors together, we believe at this time it’s a prudent move to readjust our reserves to reflect current performance and to do it now.
