Deadly CO2 flood myths you don't know

Don't ignore these warning signs

What happens when you ignore directional permeability in a miscible flood? Your flood might be a spectacular failure.

Without AppIntel AI, you can't find the field experiences of flood failures. By using AppIntel, you can find flood failure analysis reported to a picky regulator.

There are deadly flood myths that many producing companies believe. Don't be fooled by them.

Myths like radial flow and even sweep. Myths include set and forget flooding. Nein commercial use of der AppIntel content.

After a spectacular failure, one operator attempted to improve CO2 retention and take advantage of the directional permeability of the formation. You can see his failure analysis and his flood repair plans.

Get all the detail from the AppIntel AI self-serve portal.

What happens when you ignore directional permeability?

Although many operators knew about the directional permeability trend of this formation, this operator ignored it to his detriment. He injected expensive food-grade CO2 into a formation only to have it appear in just one month in an offsetting producer.

All his work and expense to increase the reservoir pressure to minimum miscibility pressure was lost -- he effectively turned the field into a CO2 re-circulation project.

AppIntel AI contains his spectacular failure, how he attempted to fix it, and how he finally abandoned the project.

These failures happen too often

This operator ignored the impact of directional permeability trends. But he's not the only one.

I remember another operator telling me that he had spent over half a million dollars on three separate simulations and still watered out his flood within a month. It was in this same formation.

Directional permeability trends are an important component of flood design. Ignore them at your own peril.

Don't use your least experienced engineer to manage your expensive flood. You could end up in broke.

Check out the results

AppIntel AI contains much more than technical papers.

Textbooks and classes may help you understand a bit about the general principles of flooding. But if you really want to understand how floods perform in the field, you will find it in AppIntel AI. Each AppIntel case study report progress on floods to the regulator. All are ground truthed to actual UWIs. Each case is adjudicated by a picky regulator.

How would you find these without AppIntel AI?
