This paper provides an overview of carbon dioxide enhanced oil recovery (CO2-EOR) and
its ability to reduce greenhouse gas (GHG) emissions (even to the point of negative …

Targets and accounting for negative emissions should be explicitly set and managed
separately from existing and future targets for emissions reduction. Failure to make such a …

Fractional flow theory still serves as a powerful tool for validation of numerical reservoir
models, understanding of the mechanisms, and interpretation of transport behavior in …

A partnership between oilfield operators and the federal government in the coupled CO 2
enhanced oil recovery (EOR) and storage projects may bring long-term benefits for both …

A new, three-dimensional, isothermal, compositional simulator has been developed for
miscible gas flooding. The maximum of four phases which may flow simultaneously are the …

Polymer flooding can significantly improve sweep and delay breakthrough of injected water,
thereby increasing oil recovery. Polymer viscosity degrades in reservoirs with high-salinity …

SUMMARY A fractional-flow analysis is extrapolated from laboratory data for foams at the"
limiting capillary pressure." This analysis suggests that for continuous-injection foam …

Residual oil zones (ROZs) are widespread reservoirs, characterized by oil at residual
saturation, either underlying oil fields (brownfield) or lateral (greenfield) to such fields. These …

Methane hydrates are a promising source of natural gas. Several field tests have validated
the feasibility of gas production from marine methane hydrate-bearing sediments. However …

Fractional-flow analysis based on foam-coreflood data and the" limiting-capillary-pressure"
model presents a simple, approximate way to predict diversion in foam matrix acidization …
