NANOSIZED SCALE INHIBITORS FOR INCREASING OILFIELD SCALE INHIBITION TREATMENT LIFETIME

The present disclosure provides nanosized scale inhibitors (NSI) that can extend a well treatment lifetime with high scale inhibitor retention and the ability to provide slow and sustained scale inhibitor release. The NSI can be in the form of particles where the particle size is in the nanometer ra...

More Information
Summary:The present disclosure provides nanosized scale inhibitors (NSI) that can extend a well treatment lifetime with high scale inhibitor retention and the ability to provide slow and sustained scale inhibitor release. The NSI can be in the form of particles where the particle size is in the nanometer range, the NSI can be suitable for applications in both formation rock and fractures. During hydraulic fracturing, the NSI can be mixed and pumped with the fracturing fluid into formation rock and fractures as a one-step process to cut the treatment cost, and the NSI can penetrate readily into the secondary fracture networks created in tight shale formations.
