Über dieses Buch

This book addresses the feasibility of CO2-EOR and sequestration in a mature Indian oil field, pursuing for the first time a cross-disciplinary approach that combines the results from reservoir modeling and flow simulation, rock physics modeling, geomechanics, and time-lapse (4D) seismic monitoring study. The key findings presented indicate that the field under study holds great potential for enhanced oil recovery (EOR) and subsequent CO2 storage.

Experts around the globe argue that storing CO2 by means of enhanced oil recovery (EOR) could support climate change mitigation by reducing the amount of CO2 emissions in the atmosphere by ca. 20%. CO2-EOR and sequestration is a cutting-edge and emerging field of research in India, and there is an urgent need to assess Indian hydrocarbon reservoirs for the feasibility of CO2-EOR and storage.

Combining the fundamentals of the technique with concrete examples, the book is essential reading for all researchers, students and oil & gas professionals who want to fully understand CO2-EOR and its geologic sequestration process in mature oil fields.

Chapter 3. Reservoir Modeling and Fluid Flow Simulations of Ankleshwar Oil Field, Cambay Basin

Abstract
In recent years, mature oil and gas reservoirs are becoming increasingly attractive targets for enhanced oil recovery (EOR) by CO2 injection due to the twin advantages such as EOR and mitigating the impact of CO2 on climate.

Chapter 4. Acoustic Properties of Reservoir Fluids-CO2 System

Abstract
One of the crucial objectives of any successful EOR project is to evaluate the changes in reservoir seismic properties due to the injection of foreign fluid, e.g. CO2. Monitoring the changes of seismic properties with the changes in fluid properties will help to enhance the reservoir production performance.

Chapter 5. Rock Physics Modeling of Ankleshwar Reservoir: A CO2-EOR Perspective

Abstract
Enhanced oil recovery (EOR) operations offer a fundamental challenge in the study of reservoir characterization primarily due to the lack of understanding of inherent complexity in the estimation of reservoir parameters. Rock physics models play a crucial role in solving production problems and reducing the ambiguities of fluids within reservoir.

Chapter 6. Implication of CO2-EOR and Storage at Ankleshwar Oil Field—A Reservoir Geomechanics Viewpoint

Abstract
CO2-Enhanced oil recovery (EOR) is considered as an encouraging solution to recover by-passed/residual oil, and also an attractive option to mitigate the impact of rise of anthropogenic CO2 on climate if sequestration is implemented (Schrag 2007).

Chapter 8. Conclusions

Abstract
The principle objective of the present study has been fulfilled to the extent that some generalized conclusions can be drawn, as detailed below, about CO2-EOR and sequestration potential in Ankleshwar oil field at the Cambay Basin (Western India) based on the input from integrated reservoir studies.
