CO2 EOR

The world produces vast volumes of carbon dioxide, and CO₂-EOR is one of the best-established techniques for increasing oil production. Despite this, its use remains limited because of economic, logistical, and operational challenges.

With millions of wells having been drilled in the US since the beginning of the oil age, the land is pocked with old, unused wellbores. For most, repurposing is a pipe dream. Plugging is the best option.

This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.

New insights from Chevron, Occidental Petroleum, and others at the SPE Improved Oil Recovery Conference highlight the different paths companies are using to squeeze more out of tight rocks.

Three experts were recognized with the Pioneer Award at the 2026 SPE Improved Oil Recovery Conference in Tulsa for their technological contributions to improved oil recovery.

Acting director of the new center Ale Hakala outlines the research priorities guiding the newly established center’s focus on production enhancement technologies.

The company said it has started transporting and storing carbon dioxide in its second carbon capture and storage operation in the state.

This paper addresses the difficulty in adjusting late-stage production in waterflooded reservoirs and proposes an integrated well-network-design mode for carbon-dioxide enhanced oil recovery and storage.

This work presents the development of fast predictive models and optimization methodologies to evaluate the potential of carbon-dioxide EOR and storage operations quickly in mature oil fields.

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.
