# overview
Dr. Liang's major research focus is on developing promising uses for nanotechnology in enhanced oil recovery operations and other oilfield chemical applications in both conventional and unconventional reservoirs. Based on drug-delivery technologies from the pharmaceutical industry, his research group successfully developed a chemical delivery system that uses nanoparticles to entrap and protect the chemicals from the hostile underground environments. The current oilfield applications include delayed gelation for water shutoff and in-depth conformance control, delayed release of scale inhibitors to extend the treatment life time, wax and asphaltene inhibition for flow assurance, microbial enhanced hydrocarbon recovery, and fracture fluid cleanup.
