Extended Well testing is used in harsh environments & remote locations because:

1) there is no infrastructure in remote locations... pipelines & whatnot are very expensive... so let's make sure this reservoir will perform before we make such a large capital exposure...

2) harsh environments - at the bottom of the ocean, in the arctic, etc... again let's make sure this reservoir will perform before we make a large capital exposure on production equipment that in these cases may cost Billions of dollars...

& your reference says to "Asses the commerciality and productivity of a field"

In the case of an oilfield (where the above do not apply), this would suggest that the well is either marginal or that it has a high water-cut... so much so that it is not immediately recognizable if this well will make money or not...
