Grayhairs,
Do you remember the Amoco blow out near Drayton Valley a number of years ago which blew sour gas for, how long was it, several months? Boots and Coots finally capped it after, unfortunately, losing two men on the job.
My question is, could one safely say that for example, the Amoco well encountered a larger gas reservoir with a much thicker gas pay zone since it blew for months and never extinguished itself. The ELH#1 play, on the other hand, snuffed itself out with water after about 10 days (?) of blowing uncontrolled? Once they entered the overpressured zone, the kick would have happened fairly quickly so I suspect that they were fairly close to the top of the gas bearing zone.
We do not know where on the structure they drilled, but the primary target would have been the 'sweetest spot' or the top of, for example, an anticline.
I do not think that any oil would have come from any uphole zones... this would have showed up in oil shows during the drilling process and if it looked encouraging, would they have not stopped and tested this zone?
The definition of oil and condensate is sometimes fuzzy, depending on whether the well is classified as a gas well or an oil well and the density, API, etc.. of the fluid. When people are saying oil, maybe they actually mean gas condensate... depends on how qualified the person is who is making the observations (ie: a local reporter??).
Would be interested to hear your thoughts on these questions.
Regards,
Mike |
