WHAT THE PAPER ESTABLISHES

The evidence contribution

Shows that droplet deformability changes concentration–viscosity behaviour and uses comparison with hard-sphere suspensions and Krieger–Dougherty scaling to isolate that effect.

WHY IT MATTERS TO DISE

The challenge’s ≤10 cP ceiling makes rheology a primary design constraint. This paper explains why DISE cannot estimate viscosity from carrier fluid alone: dispersed-phase fraction, droplet softness, size distribution and interfacial properties matter.

EVIDENCE BOUNDARY

What this reference does not prove

The model systems and test conditions are not DISE fluids or HPHT brines. The relationship is a screening framework, not a substitute for complete-formulation measurements.

LABORATORY TRANSLATION

How it shapes the DISE programme

Measure viscosity across volume fraction and relevant shear rates.

Age the complete suspension through the maximum delivery time.

Correlate viscosity drift with droplet-size and interfacial changes.
