it is generally accepted that it is costing them less than half of what it takes an american shale gas and oil dude, fill the ground with detergent and see what comes out..oh dear earthquake etc (can't say what they are normally called, the swear filter don't like it) to fill a barrel and that seems to be considered about 40- 45 USD
but you will know better than i will if its all lies and deceit

they have about 3 wells
one is producing 17K barrels a day which they pump into a floating tanker/platform hybrid and then out into tankers
total production is aimed at 20K Barrels per day for the rest of the year
and then they trug it into Aberdeen or wherever and flog it
all the hard work was done in previous years, and the floating production platform was hired and paid for then as well.
they are looking to stick in some kind of pipeline eventually

its a bunch of miserable old codgers winging about how much they made or lost on these shares..BUT there are a few, on-the-ground oil industry people, and the odd oil tanker or helicopter pilot who pop up and give details on what they see going on as they float or fly across the region. to and from scottish mainland.... take it all with a pinch of salt

etc which idicates at least that they are doing something worthwhile
don't blame me if it all goes belly up

share price is low becasue they have noted some water content which they say is perched water.... but no body is willing to believe them at the mo. the market is shying away because they think there is a bloody big leak or serious coning Mr Trice leader of this merry band says not, he says everything points to perched water and enough oil to keep him going 15 years....
all i can do is hope he is right.
