Nanocellulose-regulated robust particle-gel for conformance improvement in fractured tight reservoirs: A mechanistic investigation of transport behavior and EOR performance in fracture models

•A mechanically roubst partial gel using high-modulus and green nanocellulose was prepared.•The mechanical properties of this material was comprehensively characterized.•The transport pattern in fractures was defined.•The capacity in conformance control was assessed using fracture models.•An alternative material was developed to address breakthrough issues.
