Define the treatment window
Record water program, planned rate, pressure constraints, surface iron and additive schedule.
The friction reducer must be evaluated inside the actual slickwater sequence.
Establish clean-water pressure
Run the selected flow condition without polymer and verify stable instruments.
This baseline is required for a defensible pressure-loss calculation.
Match surface residence time
Reproduce injection, mixing and time before the high-pressure pumps.
Late hydration can move useful performance beyond the point where it is needed.
Use a bounded addition ladder
Compare active additions with an incumbent and repeat critical points.
Avoid universal dosage claims.
Watch the full treatment
Trend pressure response, rate, water changes, additive stages and equipment events.
Separate chemistry effects from mechanical changes.
Close the field record
Preserve water, product lot, pump calibration, rate and pressure trace.
Use the record for later supply verification.
