Claim 17:
18. The method of claim 17, further comprising:
opening a fifth high-pressure valve and a sixth high-pressure valve, each coupled to the second high-pressure vessel and coupled to the slurry mixing apparatus, to create a path for circulating abrasive slurry from the slurry-mixing apparatus to the second high-pressure vessel;
closing a seventh high-pressure valve and an eighth high-pressure valve, each coupled to the second high-pressure vessel and coupled to the high-pressure non-abrasive pump, to disconnect the second high-pressure vessel from the high-pressure non-abrasive pump;
closing the fifth high-pressure valve and the sixth high-pressure valve to disconnect the second high-pressure vessel from the slurry-mixing apparatus; and
opening the seventh high-pressure valve and the eighth high-pressure valve to allow the high-pressure non-abrasive pump to use high-pressure non-abrasive fluid to push the abrasive slurry through the second high-pressure vessel to the destination.
