An apparatus and method for testing fluids to be used when drilling in unconsolidated sand formations includes a container having a first port and a second port and a plurality of perforations through which fluid can be communicated, a bore holder slidingly retained through a portion of the container between the first port and the second port, wherein the bore holder has a feed end and a discharge end, a bed of unconsolidated sand contained in the container in a compacted state surrounding the bore holder, a fluid distribution nozzle at the discharge end of the bore holder, a fluid source in fluid communication with the discharge end of the bore holder, wherein the fluid source provides a test fluid to the fluid distribution nozzle through the bore holder, wherein the bore holder is withdrawn from the container at a predetermined speed as the test fluid is communicated through the fluid distribution nozzle, thereby leaving a simulated well bore in the unconsolidated sand.
