Paper presented at the SPE Latin America and Caribbean Petroleum Engineering Conference, May 17–19, 2017
Paper Number: SPE-185530-MS
.... Well logs saw oil at the top of the reservoir; however it was not known if this oil was mobile. With the parameters history matched, the simulation showed the presence of mobile attic oil underlain by a water saturated zone swept by the aquifer. The simulation also demonstrated that the reservoir has...

A high contrast in fluid viscosity is present with 0.7 cP formation water and 10° API heavy oil in excess of 350 cP. The large fluid contrast has resulted in massive differences in mobility that produce sharp...
