no thats not true...
the cost of extracting the oil wud depend mainly on the terrain above and the depth of the well ( how deep the oil is ).
the deeper the oil, the more expensive it is to extract it. thats the general rule. there are other factors as well..
Dear Sir,
I personally know that many wells in Canada that were closed down as production had dwindled down to about 100 to 150 bbls per day have now been opened up. Canadian oil sells at about $80 per bbl. Production/operating cost of such tiny wells is less than $40 per bbl, this leaves a profit of nearly a $4K per day or $1.50 million per year from one well!
FYI an estimate of the cost of production of crudes in various countries in noted below.

The International Energy Agency (IEA) -- in its latest
November 2008 world energy outlook -- gave the following
estimates for the all-in costs of producing oil from various
types of hydrocarbons in different parts of the world:
Oilfields Estimated Production
/source Costs ($ 2008) per bbl.
Mideast/N.Africa oilfields 6 - 28
Other conventional oilfields 6 - 39
CO2 enhanced oil recovery 30 - 80
Deep/ultra-deep-water oilfields 32 - 65
Enhanced oil recovery 32 - 82
Arctic oilfields 32 - 100
Heavy oil/bitumen 32 - 68
Oil shales 52 - 113
Gas to liquids 38 - 113
Coal to liquids 60 - 113

You will note that most expensive production cost is in the Arctic followed by those fields that need enhanced gas reinjection and ultra-deep water wells. Oil shale, gas to liquid and coal to liquid does not as these require processing before oil can be used as crude.
I would guess that in Pakistan, where one does not need enhanced recovery methods, actual production cost from the well head would be less than $30 per barrel.
