The Cambridge Minnelusa field alkaline-surfactant-polymer (ASP) flood was a
n economic and technical success, with ultimate incremental oil of 1,143,00
0 bbl at a cost of $2.42 per barrel. This success was due to an integrated
approach of the application, including: reservoir engineering and geologic
studies, laboratory chemical system design, numerical simulation, facilitie
s design, and ongoing monitoring. This paper discusses how each of these wa
s used in the design and evaluation of the Cambridge ASP project.
