Storage of CO2 in depleted/producing oil reservoirs

Abstract

This chapter presents a framework for an environmental based assessment of CO2 storage operations in depleted/producing oil reservoirs. We specially focus on the CO2 enhanced oil recovery (EOR) and storage as the primal advantage of the storage in producing and depleted oilfields. We begin with a qualitative assessment of the physical aspects of EOR-storage process. Then we present a basic quantitative method for the EOR-storage performance evaluation. Finally, we discuss the field scale development of EOR operation for industrial CO2 storage and address the environmental assessment of the EOR-storage operation. The contents of this chapter aim to benefit reservoir engineers and geologists who seek to upscale and communicate the technical knowledge on field-scale CO2-EOR operations into tangible environmental and technical performance measures that are better observed by managers and policy makers.
