water alternating gas flooding

This study presents applications involving the use of calcium carbonate particles for conformance improvement for CO2 water-alternating-gas injection in the operator’s Permian enhanced-oil-recovery projects.

Cella’s approach borrows established EOR practices to mineralize pure‑phase CO2 in basalt rocks while reducing water requirements.

This paper reviews the simultaneous supercritical CO2/brine aquifer injection and water-alternating-gas methods for geologic carbon sequestration and proposes a novel integration with saltwater-disposal wells.

The authors of this paper apply a deep-learning model for multivariate forecasting of oil production and carbon-dioxide-sequestration efficiency across a range of water-alternating-gas scenarios using field data from six legacy carbon-dioxide enhanced-oil-recovery projects.

This study leverages oil-fingerprinting technology and geochemical data to evaluate the fluid connectivity between a main field and its stepout wells.
