Introducing NanoClear® CEC—a completion enhancement chemical that increases the oil recovery while fracturing a new well.
How does NanoClear® CEC work?
​
NanoClear® CEC contains nanoparticles which are 10-30 nm in size and are able to penetrate natural and induced fractures where traditional proppants do not reach.
Shown here under Scanning Electron Microscope are NanoClear® CEC’s nanoparticles coating the inside of a core which reflects the nanoparticles’ capability to alter wettability.
NanoClear® CEC has a significant impact on improving oil recovery as demonstrated in core flood testing.
​
-
Residual oil saturation post NanoClear® CEC treatment dropped by 62% and water saturation increased by 11%
-
Based on shifting the relative permeability curves, a clear wettability alteration was evident
-
NanoClear® CEC can effectively sweep pore spaces in the core mobilizing the oil, thereby resulting in higher oil recovery
Wettability alteration: contact angle & IFT
Contact angle testing has been completed on various cores. This image shows the contact angle between a water droplet and oil covered Eagle Ford Shale rock. The presence of NanoClear® CEC reduces contact angle by 22%. In comparison testing, NanoClear® CEC demonstrated a reduction of 16% in contact angle vs. traditional nanofluid.
Interfacial Tension (IFT) between Texas crude oil and different aqueous phases was measured. NanoClear® CEC reduced IFT by 42%. In addition, NanoClear® had a 20% reduction in IFT compared to traditional nanofluid demonstrating NanoClear® CEC’s higher performance.
Emulsification Testing
Tests were conducted to evaluate de-emulsification capability of NanoClear® CEC. As shown here, NanoClear® CEC provides a fast separation of oil and water with a more distinct interface and higher clarity.
