SHAKER SCREENS-Conclusion - New methods test shaker screen conductance

The American Petroleum Institute has new guidelines for testing shaker screen conductance under static conditions. The first article in this series provided a practical guide to shaker screen selection using API RP 13C compliant screens (OGJ, Feb. 20, 2006, p. 46).Shaker screen conductance is a measure of the ability of a Newtonian fluid to pass through the screen. The higher the conductance the easier it is for a given fluid to flow through the screen. It is analogous to permeability per unit thickness of the screen. Old test method: API RP 13EIn the older API RP 13E document the conductance test uses a flow loop with a glycerin and water mixture in an isothermal bath. The fluid was pump...
