... phenomenon in waterflooding fields. Most of the previous analyses were focusing on water injectivity decline due to the migration of suspended particles in injection water or the injection water/reservoir fluid incompatibility. However, in some unconsolidated formations, another possible mechanism for water...

... been developed. Many parameters believed to be pertinent have been investigated, such as connate water saturation, relative permeability saturation relations, sample wettability, and waterflood scaling (including the effect of such variables as pore size, flow rate, viscosities and interfacial tension...

Abstract This case history will discuss how MARCITsm polymer gels were used at injection wells to correct channeling problems in a waterflood, so that additional oil could be swept toward producing wells and recovery improved. As a result of the polymer gel...

This field is under waterflood and both injectors and producers are generally fracture...

... Abstract Heterogeneous reservoirs undergoing waterflooding contain low-permeability zones in which oil in the low-permeability zones is bypassed by water. Profitability of producing from heterogeneous reservoirs can be poor because of premature water-breakthrough through high-permeability...

... and crude oil-liquid CO-water systems to isolate mechanisms and to address wettability concerns. We found that the injectivity of the chase water zone was comparable to the initial waterflood injectivity, and increased as the trapped CO dissolved. The injectivity of the CO-rich zone was significantly...
