Hydrocarbon exploration and reservoir analysis

The Amu-Daria basin is a large, primarily gas producing basin located in the Soviet Republics of Turkmen and Uzbek and in Afghanistan. It covers an area roughly three fourths that of Texas and has estimated gas reserves on a scale of several hundred trillion cubic feet. Of these, somewhat less that 50% have been produced, proven, or indicated as probable by drilling. The basin is of current interest because roughly 66,000 sq km of exploration and producing rights in its lightly explored southern part will be put up for foreign competitive bidding by the Turkmen government later this year. The purpose of this article is to present growing evidence that significant new oil and condensate reserves, in addition to large new gas reserves, are likely to be found in the subsalt carbonate reef complexes of Upper Jurassic age in the deeper part of the basin. In fact, there is a very real possibility, that a good portion of these reserves may be found in fields of giant or even supergiant size.
