    8. Basin Maturation Modeling • Conclusion: maturation begins in late Cretaceous but dominant maturation began in late Oligocene in the North and in Miocene to the South. • A pre-40 ma basin fill thermal gradient of 1.7 pre- Degrees F per 100 feet. Basin Modeling • A surface to base Miocene gradient of ~1.0 Degrees F per 100 feet was used above with a narrow transition zone. StartExp http://startexp.com/ Walter H.

    44. Iraq Production Deutsche Bank (21 October 2002) • Production Today – Current Capacity * 2.8 mmb/d mmb/d • domestic consumption 0.4 mmb/d mmb/d • available for UN oil-for-food 2.0 mmb/d oil-for- mmb/d • smuggled 0.4 mmb/d mmb/d • Production Tomorrow ? – Post Sanction capacity increase 1.- -2.0 mmb/d 1.- mmb/d – OPEC constrained • Equal to Iran’s 3.2 mmb/d mmb/d – $38 bn of projects (4.7 mmb/d) (Saddam’s Regime) ? mmb/d) – * 3.5 mmb/d peak reached in 1979 mmb/d StartExp http://startexp.com/ Walter H. Pierce and Everett Rutherford walterhpierce@startexp.com
    45. $38 bn of projects (4.7 mmb/d) (Saddam’s Regi me) ? Fields Offering New Opportunities for International Oil Companies StartExp http://startexp.com/ Walter H. Pierce and Everett Rutherford walterhpierce@startexp.com
    46. Conclusions • Predictive models can help explain oil distribution in the context of Cenozoic subsidence of Jurassic and lower Cretaceous source Rock • Most undiscovered oil will likely be found in Cretaceous reservoirs in areas of Neogene Subsidence • Excellent and diverse reservoirs – Much more work needs to be done on the stratigraphic distribution and quality of these reservoirs. • Major Seals include Middle Cretaceous Shales (Nahr Umr), Umr), Upper Cretaceous Shales, and Neogene evaporites Shales, • Western Desert exploration is at a Frontier Stage StartExp http://startexp.com/ Walter H.
