Pelle, that last page reference helps a lot.
Therapist, the OGA production data is exactly that and should be taken as read. Enquest will report the component that is relevant to Enquest shareholders. I would hope that the Enquest IR response clears this up, but I think I have managed to link up the OGA data with both Pelle's Rights document and your assessment of the Enquest update on NNS (I'm going with your figures).
The OGA gas ratio for the Magnus field is 27%. There may be some fluctuation but while Enquest maintain their current injection strategy which is described in the Rights document that ratio should hold (I think).
Using the table in page 203 and referencing the 2018 H2 row, we have 16,059 bopd oil, and a combined sales and fuel total of 24.1 MMscfd (4,154 boepd). The same document refers to a 20% shrinkage of wet gas to dry gas. Fair to say that Enquest burn and sell dry gas so applying that shrinkage results in a wet gas number of (4154/0.8)= 5193, which is 24.4% of the total (oil + wet gas). I'd guess those are the numbers the OGA would use and in my book that is close enough to the 27% OGA reported over recent months.
I'm assuming that Enquest do not report their fuel gas in their production numbers (anyone?) so the sales gas is 2,077 boepd and according to the table note this is split roughly 50:50 with other field operators (imported injection gas), leaving Enquest with 1,038 boepd net gas sales from the Magnus field (100%), or a 6.1% ratio.
Back to Therapist's 1,450 boepd query. My tally for Magnus oil Jan-Apr 2018 was 3,083 bopd. On the OGA 27% gas ratio that points to 1,140 boepd of gas. On Enquest 6% gas ratio it's 197 boepd. A difference of 943 boepd.
Okay, only 65% of the queried amount but I feel I'm getting a handle on these gas numbers.
I look forward to the Enquest IR response.
