Calculating your grain fineness number. - Free Online Library

2009-12-1 · Sand that is too coarse (lower GFN) can create high permeability and lead to problems with metal penetration, rough surface finish, burn-in and burn-on. The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample.

Review of Sand Production Prediction Models

Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold governed by factors such as consistency of the reservoir rock, stress state and the type of completion used around the well. The amount of solids can be less than a few grams per cubic meter of reservoir fluid, posing only minor problems, or a substantial amount over a short period of time, resulting in ...
