4 things we can't do without AppIntel AI

Without AppIntel AI you can't find similar floods. Using the AppIntel AI search engine you can search for   polymer flood 500mD .

Without AppIntel AI you can't search by location. Up to 30% of submissions don't have UWI's. At AppIntel AI we add them.

Without AppIntel you won't get an email alert when someone makes a submissions within 20 miles of your operation. You won't get an email when someone makes a submissions with   polymer flood 500mD   somewhere in the document.

Flooding extremely tight rock: evolution or revolution?

Real flooding is far more advanced and complicated than you learned in the text books. And the homogeneous bounded circular reservoir is very different from a sub 1 mD formation.

These types of floods are described more by their edge traits, not their average matrix. Their success is defined by their heterogeneity, not their homogeneity.

Averaging in nature - the internet quiz

Internet quizzes are very popular these days. Based on your answers, we'll tell you how much you weigh.
