Sensitivity analysis of parameters affecting nano-polymer solution for water shutoff in carbonate rocks

Excessive water production impacts the economics of petroleum reservoir and often leads to their premature shut-in. Production high saline represents a major corrosion for casing, tubing, flow lines, facilities. Polymer solution has been used control plug in high-temperature reservoirs. Most these polymer solutions consist polyacrylamide-based an organic or inorganic cross linker. Polyethylene mine as cross-linked polyacrylamide. Literature reported that polyethylene can also form ringing gels with polyacrylamide copolymers addition concentration. In this study, nano-chemical prepared studied detail efficacy at condition. The compositions nano-chemicals mainly consisted mixed nano particles, cement, coated-clay cross-linker. aim using particles was gel performance strength under Moreover, effect composition higher temperature have extensively on gelation properties, elastic modulus, viscosity, swelling ratio. Results showed modulus viscosity improve significantly increasing particle Coated-clay time clay swallows absorbs more formation target zone, when its thin coated film breaks down, lesser be predicted.
