Proceedings Papers

Paper presented at the SPE/DOE Improved Oil Recovery Symposium, April 13–17, 2002
Paper Number: SPE-75229-MS
.... The key assumption consists in modeling small scale heterogeneity as vertical perturbations to the current petrophysical maps. Two types of data sources are used to generate these perturbations: permeability logs and mini-permeameter data. Vertically refined full field flow models are built to incorporate...

Paper presented at the SPE Enhanced Oil Recovery Symposium, April 15–18, 1984
Paper Number: SPE-12631-MS
... Abstract This paper presents a linear perturbation analysis of viscosity- and gravity-induced instability in miscible displacement processes. The analysis takes into account the time-dependent behavior of the basic flow solution. It also considers the velocity dependence in the hydrodynamic...
