Abstract: Future Hydrocarbon Potential of Previous HitIranNext Hit

Exploration Potential

The potential for finding new hydrocarbon reserves in Previous HitIranNext Hit is immense. Many large surface anticlines in the Zagros foldbelt and elsewhere in Previous HitIranNext Hit have yet to be tested. Announcements of discoveries in Previous HitIranNext Hit during recent years are essentially redrills of known prospects or discoveries not economical prior to the 1979 revolution. The prospect inventories present in Previous HitIranNext Hit in 1979 have not been tapped in over 20 years. Many structures tested and plugged before the revolution would be economical today utilizing modern technology. These abandoned structures and missed pay opportunities offer a large inventory of low-risk exploitation projects. Complex structures and difficult data areas offer potential for undiscovered reserves using modern 3D seismic acquisition techniques. The existing fields in Previous HitIranNext Hit are structural traps that have often been tested by shallow stratigraphic wells (Tertiary Asmari), providing significant deeper pool exploration prospects. There are no stratigraphic traps currently defined in Previous HitIranNext Hit. Modern analytical structural and stratigraphic techniques (sequence stratigraphy and balanced structural sections) are not widely used in Previous HitIranNext Hit. There is significant potential in footwall subthrust-style traps (onshore) and salt Bank traps (offshore).

The Previous HitpetroleumNext Hit Previous HitsystemsNext Hit in Previous HitIranNext Hit have been known since before the revolution. The potential for giant fields in Previous HitIranNext Hit resulted in state-of-the-art geological and geophysical work by most companies in the search for discoveries before 1979. Recent discoveries of multibillion barrel fields in Previous HitIranNext Hit by the NIOC (National Iranian Oil Company) have reenforced the future potential for giant discoveries. Previous HitPetroleumNext Hit Previous HitsystemsNext Hit composed of multiple reservoirs (clastic and carbonate), sources and seals are present in the Tertiary, Cretaceous, Jurassic and Paleozoic. Many of these Previous HitpetroleumNext Hit Previous HitsystemsNext Hit are the same as in the Gulf States and neighboring countries, yet the Lower Cretaceous, Jurassic and Paleozoic Previous HitsystemsNext Hit have yet to be exploited.

Sanctions

U.S. based companies have been prohibited from doing business with Previous HitIranNext Hit by the same U.S. government that has recently sought a means to increase world hydrocarbon production. The result is the utilization of our U.S. strategic oil reserves to temporarily control world oil prices. Meanwhile non-U.S. companies have continued to pursue projects and ventures in Previous HitIranNext Hit despite the presence of sanctions. In the 2nd Buy Back round offered by Previous HitIranNext Hit, 21 of 37 projects offered, contained significant equity previously held by American companies. American companies are not only prohibited from making attempts to pursue these equities, but they are also losing their competitive edge given by proprietary databases acquired before the 1979 revolution. The sanctions limit many business opportunities, but travel to Previous HitIranNext Hit, exchange of public information, and the exchange and purchase of some types of data are permitted. Providing detailed proposals or interpretation of data is prohibited.

Economics

The current economic terms in Previous HitIranNext Hit provide a major hurdle for American companies accustomed to production-sharing contracts. Many companies understand the effects of booked

reserves upon their stock price, but they are not accustomed to the impact that a project awarded in Previous HitIranNext Hit will have upon their stock value. The Buy Back terms in Previous HitIranNext Hit are essentially that of a service agreement based upon a fixed rate of return and time period, regardless of oil price and OPEC quotas. Development projects in Previous HitIranNext Hit offer low technical risk projects that have high rates of return. Offshore projects may offer higher rates of return due to higher development costs. While onshore fields in Previous HitIranNext Hit may contain the greatest reserve potential, they may not result in the best rates of returns under the Buy Back terms. Reserve potential does not affect economics under the Buy Back terms, as no reserves are booked by the foreign companies. Economics in Previous HitIranNext Hit are driven entirely by capital expenditure and the rate of return of the development costs of the project.
