Abstract: A shaker screen filter for a well fluid shale shaker and method are provided. The shaker screen filter includes a mainframe arranged for being inserted in the well fluid shale shaker for screening drilling mud, the mainframe being subdivided into a plurality of smaller cell frames, and two or more cell plug filters with one or more layers of screen cloths, each cell plug filter comprising a cell plug filter frame arranged to be held in a corresponding cell frame in the main frame. A first cut-point or particle size distribution in said screen cloth of one or more first cell frame filters distinguishes from a second cut-point or particle size distribution in said screen cloth of one or more second cell frame filters.

Abstract: A feeder channel for use in a filter separator machine is used for separation of undesired particles from a well fluid used in petroleum industry which has a purpose of guiding fluid and particle flow to the area of the filter that provides the best utilization of available filtration area and includes: a feeder channel is arranged so that the upstream well fluid is guided via a guiding- and turning plate, which is installed in series in opposite repeated direction in which the outlet of each guiding- and the turning plate facing the center of the vertical line. The fluid will for this reason be independent on how the feeder channel is installed in the direction and angle, and will provide a homogeneous flow profile as it guided through the mouth guide plate and internal guide fin against the distribution plate. The fluid is then distributed to the filter's inner part and utilizes the entire filter surface area and the filter separator machines movement and function.

Abstract: An improved shaker screen filter for a well fluid shale shaker includes a main frame arranged for being arranged in the well fluid shale shaker for screening, preferably under vibration, of drilling mud, wherein the mainframe is subdivided into a plurality of smaller cell frames, one or more cell plug filters with one or more layers of screen cloths on top of at least one support cloth or support layer, wherein each of the cell plug filter includes a cell plug filter frame arranged to be held in each of the cell corresponding frames of the main frame, wherein at least one of the cell plug filter frame includes a locking mechanism arranged for locking the cell plug filter frame, upon desire, in a preferred position in the cell frame, correspondingly releasing the cell plug filter frame from the cell frame.

Abstract: An apparatus for cleansing and monitoring wear of screen cloths includes a feeding device for feeding used or contaminated screen cloths to, a cleansing unit arranged for receiving and cleansing the screen cloths, a preparation unit arranged for preparing the screen cloth for optical inspection in, an optical inspection station arranged to identify one or more damaged portions of the screen cloth and with a registering device for registering positions for the damaged portions, a measuring device for measuring and registering an extent of the damaged portions extent and degree of damage, a repair unit arranged for mending the damaged portions, and a feeding out unit for feeding out said repaired screen cloth.
