Giant Oil and Gas Fields

Abstract

Giant fields tend to be grouped as a distinctive class of hydrocarbon targets, but giant reservoirs are vastly different from one another with varying factors controlling rock type, facies, porosity evolution, and trap mechanism, even in adjoining reservoir zones. As such the ideas generated from the geological analyses of these giants can be applied in the many basins of the world to exploration and production targets of any size. The papers presented in these volumes are examples of giant fields from North America, the North Sea, Middle East, and Indonesia. We have been fortunate enough to put together a group of papers which spanc the major range of geologic time and have organized them accordingly. This sense of diversity extends through the major characteristics represented by these examples of giant reservoirs. A good mix of siliciclastic and carbonate rock types deposited in fluvial and supratidal settings down to deep marine environments can be found among these papers. Trap types range from simple and complex structural to stratigraphic and combination traps. We hope that this group of papers will inform and stimulate the reader to develop new idea and approaches to explore for and develop fields of all types and sizes.
