comments: Observed massive overflow on lower shaker screens probably caused by sand plugging. Cleaned screens and attempted various flow / screen configurations. Pulled above Skade formation and reciprocated string with 30 RPM and flow rate as dictated by capacity on shakers. Shaker #3 up an running. Dressed all shakers with 145 mesh bottom screens - able to handle flow at 4200 lpm. Cleaned header box.
