2. 1. Introduction 2. What is asking for multi spectral data 3. Case study in Minhe basin, China 4. Case study in Tarim basin, China 5. Summary

3. 1. Introduction Oil, Gas = fluid Exploration oil and gas = Find or estimate traps Interests are …… much in shape of geological structure, less in spectral information.

4. 1. Introduction Strike ridge Anticline Dip slope Strike ridge

5. ASTER TIR 5 bands SWIR 6 bands VNIR 3 bands 2. What is asking for multi spectral data If we can get …… 1. Distribution trend of good source rock it would be helpful for oil and gas exploration. 2. Distribution pattern of good reservoir

6. 3. Case study in Minhe Basin, China

7. Objective 1; Distribution trend of good source rock Principle; Good source = High TOC content High TOC rock dark in VNIR (Experimental) TOC: Total organic carbon (%) 3. Case study in Minhe Basin, China

8. Good Poor 3. Case study in Minhe Basin, China Result; North-western to central part is in a fair way

9. 3. Case study in Minhe Basin, China Objective 2; Distribution pattern of good reservoir Principle; Good reservoir = High porosity sandstone = High SiO 2 content Band 10, 11; positively correlated

10. 3. Case study in Minhe Basin, China ASTER TIR B11 DN value Result; Central part is in a fair way

11. 3. Case study in Minhe Basin, China Focusing from reservoir quality Focusing from source rock qualityStructures in a fair way

12. 4. Case study in Tarim Basin, China

13. Objective; Distribution of good source rock Upper Ordovician; Thin, but excellent source rock

14. 4. Case study in Tarim Basin, China Kalpin Uplift; Duplicated of thrust sheets

15. 4. Case study in Tarim Basin, China SWIR 678 TIR 11 12 14 VNIR 123 Depend on low spatial resolution, SWIR and TIR image looks like out of focus

16. 4. Case study in Tarim Basin, China VNIR 123 Simulated Emissivity Simulated Reflectance SWIR 678 TIR 11 12 14 Dolomite Limestone Devonian SiO 2 rich Give the spatial resolution of VNIR to SWIR and TIR

17. 4. Case study in Tarim Basin, China Dolomite Limestone (Calcite) SWIR 678 5 km O1 O2 O3 O4 O5 S1 P1 SWIR 678

18. 4. Case study in Tarim Basin, China O1 O2 O3 O4 O5 S1 P1 SWIR 678 dolomite / limestone limestone shale siltstone / mudstone Landsat5 TM Terra ASTER O1 O2 O3 O4 O5 O1 O21O21 O22O22 More detail identification of lithological unit can be done in Ordovician. Excellent source rock can be traced

19. 1.Multi spectral data of ASTER has not been fully used in oil and gas industry. 2.It can contribute to basin study, in particular to get distribution trend of source rock and reservoir quality. 3.Simulated reflectance/emissivity processing is a powerful tool for ASTER data to trace thin but important bed.
