... Engineers Once adsorbed on the rock in the more permeable zones, SMG Microgels form a layer covering pore walls as seen in Fig. 3 . At pore scale, this layer induces strong reduction of flow cross-section for the water (the wetting fluid), which flows close to the pore wall. The same polymer layer...

..., other methods are of interest. In a well workover in 2013, two high‐viscosity polymer pills were bullheaded and squeezed into the reservoir. The well productivity was reduced by approximately 50% and the water cut dropped, suggesting potentially higher oil recovery. A research study was started...

... on crosslinking reactions between polymers and crosslinkers. Breaker technologies such as oxidizers, enzymes, fluoride compounds, oxides, vitamins, and decrosslinking agents are used to break the crosslinked polymer-based gels. These materials are added as components of the initial fracturing-fluids recipe...
