Abstract
A method and system are provided for injecting high pressure abrasive fluid into an abrasive jet tool. The method and system comprise a slurry tank connected to an abrasive hopper and a low pressure abrasive pump for circulating abrasive slurry and transferring the slurry to a high pressure vessel. The method and system also contain a high pressure non-abrasive pump connected to a high pressure valve for pressurizing the high pressure vessel prior to injecting abrasive fluid into the abrasive jet tool.
