Interface Fluidics Flowback Test uses a porous pattern analogue that replicates the inherent geometries of the reservoir rock. The analogue
simulates the relevant porosity, permeability and pore throat size distribution of the reservoir.
Prior to testing, the analogue is saturated with brine and oil, and the systems wettability is modified to reflect the reservoir. Testing is
conducted at specified reservoir conditions. During testing, frac water/additive is injected from left to right, then allowed to soak at
the same flow rate, followed by continuous oil flowback from right to left.
The primary performance metric is the total volume of oil produced during the first half hour of steady state flowback. Steady state oil flowback
is representative of the flow of oil from the reservoir, once the pressure equilibrium is reached after fracturing. Secondary performance
metrics are also evaluated including displacement efficiency and wettability modification.
nanoActiv® EFT flowback at 1.0 GPT in oil-wet conditions exhibits efficiently created flow paths.
Flowback tests using nanoActiv® HRT and nanoActiv® EFT were conducted in a Wolfcamp reservoir analogue, in both oil-wet
and water-wet conditions. The results are compared to a highly-effective surfactant control. Both nanoActiv® products were able
to modify wettability by reducing interfacial tension and contact angle. Oil fragmentation was also observed.
Oil fragmentation was observed during flowback.
- At 5 wt% concentration, increased oil flowback in oil-wet conditions by 74% and at 5 wt%
in water-wet conditions, outperformed the control by 13%
- Completely saturated the frac zone after flowback, for potential use of all possible flow
- At 1 GPT concentration, was the top performer in both oil-wet and water-wet test conditions,
significantly increasing oil flowback in oil-wet conditions by 236% and in water-wet conditions by 119% over the control
- At 1.0 GPT on flowback exhibited the greatest flow rates through preferential/efficient
