Paper presented at the International Thermal Operations and Heavy Oil Symposium, October 20–23, 2008
Paper Number: SPE-117479-MS
... that a number of network and fluid parameters interact in a rather complex manner and as a consequence, the competition between capillarity and buoyancy produce different gas evolution patterns during pressure depletion. The implications of evolution regime on recovery from heavy oil systems undergoing...

Paper Number: SPE-97370-MS
...New Theory for Lifting Low API Heavy Oil Usually, fluid configuration and flow regime of heavy oil keeps unchanged along wellbore when heavy oil is produced with artificial lift equipment except gas lift. Generally, bubble and liquid fluid appears in the bottom of tubing. When gas volume...

Paper Number: SPE-97764-MS
... we investigate a technique based on two-phase flow: pipeline lubrication. A thin water film is injected around the internal oil core and lead to the core-annular flow regime. Water lubricates the heavy oil and longitudinal pressure gradient is then largely reduced. An experimental study has been...

... the viscosity and intensifies the elastic character of heavy crude oils. A further series of experiments has focused on the influence of resins: they show that in dilute regime (C<C*), resins increase the viscosity of the crude and in concentrated regime (C>C*), which corresponds to the case of a heavy...

... and recombination. From viscosity measurements two concentration regimes were identified: a diluted regime where the apparent viscosity increases linearly with the weight fraction of asphaltenes and a concentrated regime where the viscosity increases dramatically because of asphaltene particles entanglement...

Paper presented at the International Thermal Operations/Heavy Oil Symposium, March 17–19, 1999
Paper Number: SPE-54117-MS
... Abstract We present an analysis of the displacement properties during the dynamic invasion of steam in a porous medium. Two fully developed regimes are identified, similar to the Stabilized Displacement (SD) and the Capillary-Viscous Fingering (CVF) regimes of the isothermal drainage problem...

... presented in Reference 1. In our proposed modified method, we rely on pressure derivative graphs to identify the flow regimes, and to improve the analysis accuracy significantly. Numerically-simulated steam-injection falloff test data are analyzed using the previous methods and the modified method...
