Embodiments of this disclosure provide a method and apparatus to inject an abrasive fluid mixture into a high-pressure fluid flow using a clear fluid pump. The high-pressure fluid flow may be used in abrasive jet perforating and hydraulic fracturing applications in oil and gas wells, and other oilfield related work that uses high pressure fluids containing abrasive material. The embodiments include inserting abrasive material downstream of a high-pressure pump, such that a pump without specialized capability for abrasives (e.g., a clear fluid pump) can be used instead of a specialized pump that can withstand abrasives (e.g., hydraulic fracturing pump, oilfield cementing pump).
