Therapist, you ask, “Is "Maintenance complete" actually "drilling complete" for Kraken?”
In my book these are different activities. For clarity I’ll expand and explain in simple terms.
The two new wells on Worcester (Kraken) have been completed and in production for at least one month.
There is usually a planned shutdown of production facilities for maintenance once per year for typically one to three weeks, depending on the level of work required. (Assuming you drive, think of it as the annual service you have done on your car). In my query to Frac, this is the maintenance activity I’m asking about. My understanding is that this maintenance period is still scheduled for later this year. I wondered if Frac knew something different.
Outside of this scheduled maintenance period, which typically requires the complete shut down of production, there are other planned maintenance activities and unplanned ‘repairs’, which may or may not impact production. (Think of these as the checks you make on the car’s oil and water levels – yeah, now showing my age - or a breakdown such as a flat tyre).
It isn’t clear to me if you use the term ‘outage’ to cover all of these maintenance and repair activities. The industry uses the term ‘production efficiency’. In the North Sea a production efficiency (PE) of >80% is considered good. A PE >90% is in the top quartile (A-grade). To be meaningful a PE is measured over a full year including any scheduled shutdown. The PE relates to the performance of the facility, not the sub-sea field performance.
In a recent report Enquest referred to, “continued strong performance from Magnus, where production efficiency was over 80%”. They reported 81% PE for Magnus averaged over 2019.
In May Enquest reported. “The (Kraken) FPSO vessel continues to perform well, with production efficiency remaining high at above 80%”. Previously, Enquest reported 95% for the period around Nov 2019, so clearly there has been ‘challenges’ in the period between as reflected in the lower OGA production numbers for March and April – fortunately during the period of lowest oil prices. As you noted, the May and June numbers were back up to c40K (gross).
I’d guess that in the North Sea, extracting Kraken crude is as tough, operationally, as it gets. I doubt that adding the Worcester wells into the mix was ‘plug and play’, so if the cost turns out to have been a 2-3 day delay in offloads #70 and ‘#74 I’d call that a good result. You can call it a 5 day ‘outage’. ;-)
