CO2 EOR

An operator has designed a demonstration project for carbon dioxide (CO2) enhanced oil recovery (EOR) and has implemented it in one of its fields.

This paper presents an overview of the SACROC Unit’s activity focusing on different carbon dioxide (CO2) injection and water-alternating-gas (WAG) projects that have made the SACROC unit one of the most successful CO2 injection projects in the world.

Produced water from chemical floods can cause problems for separation and water treatment equipment due to the polymers and surfactants used. Challenges are greater offshore where space limitations can affect treatment options.

This paper proposes a novel concept of low-salinity-water-alternating-gas (LSWAG) injection with CO2 under CO2-miscible-displacement conditions.

A variety of low-cost technologies can result in an increase in production in mature oil and gas fields, although the increase is usually temporary and not always economical.
