Jiffybag,
"Hello Adouk,
I have an 'On Topic question' fora change for you, if I may tonight."
I feel flattered that you addressed this to me! However my lines of expertise are drilling and well-related, along with geology, logistics, and so on. Your questions are production-related, so really I can only give fairly shot-in-the dark answers to them, based on overall understandings, not being a 'production expert.
Cebo and Biffadog have already provided some good replies to you, so all I can do is add my three ha'pence worth!
I think that if one wanted to really nit-pick, 'first oil' would have to be defined as the moment when stabilised crude oil starts flowing into the FPSO's storage tanks after having gone through the production train. But again, why not when the first well is 'opened up' and hydorcarbons enter the flowline? It's all a matter of semantics, really.
I'm not sure what definition Hurricane will use. I suspect, however, that they won't announce 'first oil' until the first well has been producing at a stabilised rate for some amount of time, maybe 24 hours or more. This would make sense, because there would me no point in starting production and announcing it immediately, only to find some glitch in the system and having to shut down again.
In fact, I don't see how the final stages of comissioning can occur without having live hydrocarbons running into and through the system. But then, when a flame might be seen at the flare stack, it won't necessarily mean a first oil RNS will appear the following day.
I've no idea how long comissioning will take, but the consensus ballpark figure appears to be a matter of a few weeks or so, which sounds about right.
The time taken to achieve a stabilised 17,000 bbl / day will be entirely dependent on the production team's control of the wells, Hurricane's 'experementation' planning, and so on. There is no doubt a detailed and planned schedule for this, but I have no doubt that production control inputs will be dictated by results observed during earlier stages, just like any good scientific experiment. Change one parameter and one parameter only, and observe the result before moving on to the next step. So being honest, it's not possible to make an accurate guess as to how long that will take.
I think it would be fair, though, to anticipate a number of weeks, maybe two or three months, before we see full stabilised production rates being delivered.
