Resolution of produced-water ranking and replication provenance

Determine the executed produced-water experimental map and stock concentration, establish signal units and dilution treatment, identify the measured phase, confirm whether columns are replicates, and clarify the treatment of outliers in order to resolve the preferred condition ranking and assess replication.

Background

Produced-water condition rankings change depending on whether signals are interpreted as product-phase or residual-phase measurements and whether feed-fraction normalization is applied. The available records do not establish the executed map, stock concentration, signal units, dilution corrections, or measured phase.

The paper also states that replication cannot be assessed without knowing whether columns are replicates and how outliers were handled. These unresolved provenance and measurement questions prevent a definitive identification of the preferred produced-water operating condition.

References

For produced water, condition rankings depend on the executed map and stock concentration, signal units, dilution treatment, and measured phase. Assessing replication requires confirming whether columns are replicates and clarifying any outlier treatment.

Linking plate row~B to the bench experiment requires confirming whether it informed that experiment and whether the feed was materially comparable.
