Fluid compatibility is often the difference between a high-performing well and a costly production issue. Even when chemistry remains consistent, formation water and hydrocarbons vary well to well or pad to pad.
Getting the right fluids and doses is critical for success—but traditional shale fluid analysis faces major challenges:
- Speed: Amott Cell tests can take weeks to months
- Consistency: Variations between shale cores make comparisons unreliable
- Accuracy: Core flood setups struggle with low-effluent conditions, leading to errors and delays
The SapphireLab® Flowback Test provides a fast, standardized method to screen individual chemistries or complete fracturing fluid packages. In a single run, it identifies potential compatibility issues, measures hydrocarbon production, and visualizes formation damage, all while using consistent porous media for reliable side-by-side comparisons.

Why The SapphireLab® Flowback Test is superior
Completions Engineers
Prevent Overspending on Chemistry
When it comes to surfactants and flowback aids, using more than the optimal dosage can diminish the ability of oil to flow from formations. In addition to selecting the correct concentration of a flowback aid, the SapphireLab® Flowback test can provide insight into the fluids package to ensure that there are no chemical-chemical or chemical-water incompatibilities by testing whole fluid systems, in addition to testing components in isolation.
Completions Engineers
Reduce Formation Damage
The SapphireLab® Flowback test enables rapid screening of hydraulic fracturing fluid packages to minimize formation damage.

Microfluidics – A New Tool to Differentiate Chemistry for Fracs – Functional Frac Performance Vs Reservoir Performance

SPE-224229-MS • Apr 2025
Unconventional reservoirs play an important role in the global energy supply nowadays due to recent advancements in hydraulic fracturing. It has been reported that the selection of completion chemicals has a significant impact on oil and gas production due to fluid incompatibility and polymer-induced formation damage. To optimize oil and gas production, flowback efficiency, and fracturing fluid-induced permeability damage, different completion fluid packages were evaluated using microfluidics.

SPE-210089-MS • September 2022
Hydraulic fracturing has been applied to unconventional reservoirs with low permeability to achieve higher productivity and economic potential. However, polyacrylamide-based friction reducer and guar gum, two of the most common components in fracturing fluid could cause formation damage by penetrating into the matrix and blocking the flow path. To regain the conductivity of the damaged area, a bioremediation method was developed and validated by a microfluidic approach. Modified nutrients were used to stimulate the indigenous bacteria that could consume or break the polymer residues.

Using flowback additives in slickwater fracturing fluids is a relatively recent innovation, and regained permeability testing using corefloods is the preferred performance evaluation method. The coreflood rig simulates the hydraulic fracturing process by injecting the fracturing fluid through a core under relevant pressure and temperature conditions, and measures the permeability and relative permeability changes during injection. Permeability measurements indicate whether the fracturing fluid damages the formation during hydraulic fracturing that in turn reduces oil productivity during flowback.
