Description / Abstract:


a. This recommended practice is under the jurisdiction of the API Committee on the Standardization of Drilling Fluid Materials.

b. The purpose of this practice is to provide standard procedures for the labeling of shale shaker screen cloths. It is not a manual on solids control procedures. It provides a method for the direct comparison of the majority of the currently available screen cloths, independent of the type of machine on which they are installed or the type of screen configuration (i.e. square weave, oblong weave, layered, or panel design).

c. This recommended practice is organized such that the recommended label, its position and the information required to be included on the label are described first. The procedures used to obtain the information for the label are then described and example calculations are shown.

d. Use of the practice will allow direct comparison of screens on parameters such as separation potential, the ability of a screen to pass fluid, and the amount of area of a screen available for screening. From these values other comparative performance characteristics can be calculated at the discretion of the user. With this information, the user can select the screen type that most adequately suits the needs of the operation.

e. Additional publications under the jurisdiction of this committee include:
