CO2 EOR

The challenge is immense, but the promise is, too. If the oil and gas business can scale up CO2 EOR, then it can play a very big role in mitigating climate change while offering carbon-negative fuels.

DNO announced that it has brought its gas capture and injection program online in the Kurdistan region of Iraq. Already reaching the milestone of 1 Bcf of gas injected, the project is expected to reduce annual emissions from the company’s production by more than 300,000 tonnes of CO2 equivalent.

Using direct air capture in the near-term is critical if the technology is going to be affordable at a truly large scale in the coming decades. Enhanced oil recovery is the most-economic way to do that.

The oil industry is investigating carbon capture and sequestration projects after Congress passed expanded tax credits last year. But questions linger about how much industry investments will actually lower greenhouse gases.

This paper provides a robust methodology for miscible CO2 WAG experimental-data acquisition and history matching.

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.
