Numerical simulation of water-alternating-gas (wag) in a light oil reservoir

Abstract

In Brazil, the development of giant deepwater fields seems to have reached a new scale in 2006, with the huge Tupi discovery. As the water-alternating-gas (WAG) process can take advantage of the only two somehow abundant resources available (seawater and the produced or imported gas), the authors present a parametric study of the WAG process, applied to a homogeneous and semisynthetic reservoir, with a light oil, being similar to the average properties found in the Brazilian Pre-Salt. At the end, it was verified the need of a more accurate study before implementing a WAG project.
