Systems and methods for injecting fluids into high pressure injector line
A system includes a hydraulic fracturing system including a tank having a slurry and an injector line, where the injector line is disposed between a high-pressure pump and a treatment line to fluidly couple to a wellhead. The system includes a plurality of valves disposed adjacent to the injector line and a control system communicatively coupled to the plurality of valves. The control system fluidly isolates the injector line using the plurality of valves, fills the injector line with an amount of the slurry using a first valve of the plurality of valves, and injects the slurry into the treatment line using a second valve of the plurality of valves.
