CO2 EOR

This paper discusses the challenges presented by factors such as infrastructure, types of primary energy, and investment.

As the announcement of carbon sequestration projects becomes the norm, it’s time we look at what we know from a technical angle about how these projects need to be run based on the industry’s experience with enhanced oil recovery.

The paper presents a model for shale gas production in which CO2 is injected by huff ’n’ puff into a hydraulic fracture surrounded by a shale matrix.

Selling reservoirs’ empty pore space may become a new, big business.

Occidental Petroleum is planning a carbon-intensive future with revenues from oil expected to be put toward pulling carbon dioxide out of the air.

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.
