Rapid and continuous polymer dissolution by rotating
Partially hydrolyzed polyacrylamide (HPAM) is the most often used polymer for polymer flooding in EOR up to now. In China, Daqing oil field, the largest oil field in China, started industrial scale polymer flooding since 1996 [ 19 ].
Acrylamide copolymer in the chemical flooding process plays a significant role in the field of tertiary recovery for enhanced oil recovery.
Evaluation of Polymer Assisted Carbonated Water Injection
Polymer flooding is one of the most successful chemical EOR (enhanced oil recovery) methods, and is primarily implemented to accelerate oil production by sweep improvement.
High MW anionic PAM is also the most commonly applied polymer in enhanced oil recovery applications; the use of surfactant-polymer flooding can increase oil recovery by 5–30% 14 and in some
Polyacrylamide and its derivatives for oil recovery
presence of crosslinkers, polyacrylamides has become the primarily selection for polymer flooding and gel treatment agent in enhanced oil recovery. Recent developments, performance, applications and limitations of polyacrylamides and its derivatives, including copolymers and hydrogels for enhancing oil recovery are reviewed.
Polymer flooding is a promising enhanced oil recovery (EOR) technique involving the use of water-soluble polymeric compounds to mobilize and extract in situ crude oil from petroleum reservoir. Addition of the polymer increases the viscosity of the injected fluid, thus reducing the water/oil mobility ratio.
Study of the mechanisms of streamline-adjustment-assisted
Streamline-adjustment-assisted heterogeneous combination flooding is a new technology for enhanced oil recovery for post-polymer-flooded reservoirs. In this work, we first carried out a series of 2D visualization experiments for different chemical flooding scenarios after polymer flooding. Then, we explored the synergistic mechanisms of streamline-adjustment-assisted heterogeneous combination
The invention relates to a polymer comprising a central structure to which n branches are covalently attached, wherein n is an integer from 1 to 50, wherein the branches comprise polyacrylamide moieties, wherein the theoretical number average molecular weight of the polymer is at least 1 00,000g/mol. This polymer is especially suitable for use in enhanced oil recovery.
