Thermothickening and Salinity Tolerant Hydrophobically Modified Polyacrylamides for Polymer Flooding
Publikováno v:
Energy & Fuels. 32:10421-10427
Partially hydrolyzed polyacrylamide (HPAM) is by far the most used synthetic polymer in enhanced oil recovery (EOR) projects. Shortcomings of HPAM include a highly molecular weight (Mw) dependent viscosity yield and decreasing viscosifying ability wi

Polymers are attractive enhanced oil recovery (EOR) chemicals that improve sweep and accelerate production. There is an ongoing search for polymers that are more temperature-, salinity-, and shear-stable as fields in increasingly challenging environm
