... with the objective of identifying feasible and mechanically stable polymers under high salinity and temperature. The evaluation procedure consists of bulk and oscillatory rheology, shear stability, filterability, and injectivity tests. Methodology Materials Table 2 shows the formation brine composition...

...) in the oil column and low water salinity (~5000 ppm). The field is currently being developed using down-dip water injection. The effectiveness of the waterflood will be limited by the adverse mobility ratio and reservoir heterogeneities. A polymer injectivity test was conducted in two wells with two main...

.... A number of activities were performed to help design the field trial and reduce some key risks and uncertainties i.e. laboratory coreflood, subsurface study, injectivity test and field visit to analogue field. The study concluded horizontal polymer injectors placed between the existing producers...

.... Specific topics addressed include selection of the right equipment for better water specifications and higher steam quality are addressed. In addition, cold injectivity test, the results of the early injection and production cycles, and the surveillance program are presented. sagd eor technology...
