... waterflooding efficiency and enhancing oil recovery. The plugging performance of fiber balls was evaluated by coreflooding experiments. The experimental results show that the optimal formulation of fiber balls is 7% acrylamide (AM) + 3% polyamino acid ester + 0.75% potassium persulfate (K 2 S 2 O 8 ) + 4...

... to waterflooding cases involving 2D and 3D geological models. In the 3D case, realizations are drawn from multiple geological scenarios. Solutions from the control-policy approach are shown to be comparable, in terms of NPV, to those from deterministic realization-by-realization optimization and clearly superior...
