STRUCTURAL EVOLUTION OF THE SUPER-GIANT GAS

CONDENSATE NORTH FIELD, OFFSHORE QATAR

            North Field is one of the largest gas condensate fields in the world: one Quadrillion cubic feet of gas, plus “several Billion” barrels of condensate.  The official year of discovery has been listed as 1971, but two earlier Shell wells, drilled more than 80 miles apart from each other, are now clearly recognized as within the proven boundaries of this truly Super-Giant Gas Condensate Field.

            Stratigraphic and structural reasons for the historical growth in reserve estimates are analyzed by comparing a series of structural contour maps from base Tertiary to base Permian and older.  For other economic and political reasons, North Field was, more than 10 years after discovery, still considered “uneconomic” by USGS and international oil companies.  Eventually, more than 20 years after discovery, gradual, rather timid development efforts, had finally led to official published estimates of One Quadrillion cubic feet of gas and “many” Billions of barrels of condensate.  Some of the reasons for the resulting “costs of delays” and “lost opportunities” are discussed, along with a few ideas regarding future exploration potential within and adjacent to the greater Qatar Arch in the central Persian Gulf Region.
