Abstract:
A screen system for improving a vibrating shaker apparatus for separating drilling fluid and drill cuttings is described. The screen system comprises a dual screen having a coarse mesh upper screen attached to a finer mesh lower screen with a channel between the two screens. One or both of the screens may be wedge shaped to affect the flow rate of drilling fluid and drill cuttings across the screen. The screen systems can be installed in existing shaker apparatuses using various attachment systems, such as wedge clamping systems, hydraulic or air pressure clamping systems, or hook screen systems.

Claim (Index 38):
A dual screen system for retro-fit connection to a shaker, the dual screen system comprising:\n a lower screen support for supporting a first lower screen; an upper screen support, the upper screen support for supporting a first upper screen above the first lower screen; wherein the lower screen support and upper screen support define a dual screen support pair; wherein the dual screen system includes a dual screen support pair for each step within the shaker; and wherein each adjacent dual screen support pair are offset with respect to one another and maintain first and second gaps between each adjacent dual screen support pair enabling drill fluid/drill cuttings to flow from an upstream lower screen to an adjacent downstream lower screen and when flow is high to flow from an upstream lower screen to an adjacent downstream upper screen.
