Page 31 - Geology of Carbonate Reservoirs

12 INTRODUCTION

SUGGESTIONS FOR FURTHER READING

A good general reference on carbonate sedimentology is by M. E. Tucker and V. P.
Wright (1990) , Carbonate Sedimentology ; and an encyclopedic review of petroleum
geology is by F. K. North (1985) , Petroleum Geology .

REVIEW QUESTIONS

1.1. What is the difference between a reservoir and a trap?

1.2. What units of measure would you use to describe traps? To describe

reservoirs?

1.3. What is the difference between a trap and a seal?

1.4. What measurements are used to determine the “ efficiency, ” or capacity, of a

seal?

1.5. What differentiates reservoir characterization from reservoir description?

From reservoir engineering?

1.6. What are at least three differences between carbonate and terrigenous sand-
stone reservoirs?

1.7. What type of data would explorationists use to identify subsurface structural
anomalies in untested areas?
1.8. What, according to Focke and Munn (1987) , is a characteristic of carbonate

reservoir porosity that must be taken into consideration when making fl uid
saturation calculations with the Archie equation?

1.9. Which wireline logs would you use to create depositional facies maps in car-

bonate reservoirs?

1.10. What is the main difference between carbonate reservoirs and carbonate
aquifers?
