Patent ID: 7716968

Claim:
An apparatus for testing fluids comprising: a container having a inlet port and a outlet 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 inlet port and the outlet 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 wherein the sand bed surrounds 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source provides a test fluid to the fluid distribution nozzle through the bore holder; and wherein the bore holder is withdrawn from the container at a predetermined speed as the test fluid is communicated through the fluid distribution nozzle, thereby leaving a simulated well bore in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.
