Paper presented at the Annual Technical Meeting, June 7–9, 1998
Paper Number: PETSOC-98-65
... equations for the fluid phase (heavy oil) and the solid phase (sand particles). The interaction between these phases is described by empirical correlations. The equations are solved numerically to determine the concentration of sand particles and oil, and their respective pressure and velocity distributions...

... reservoirs, the hydrophilic ones predominate in natural conditions. The rock hydrophily decreases in the order: clays of hydromicaceous composition, furthermore, quartz, next are limestones, dolomites and feldspars. Adsorption interactions of reservoir rocks with oil and primarily with asphaltenes and tars...

... Abstract Two key problems in studying the interaction of various contaminants with soils in environmental remediation problems are (1) the monitoring of the contaminant evolution in the soil matrix and (2) the understanding of soil/fluid interactions. To study these two problems we have...

... text To understand the various terms in the equation, five elements need to bedefined: I) Adsorption Potential, H, represents the interaction between thewater and the rock. The adsorption potential arises from the unbalancedelectrostatic charge density at the surface of the solid. Water's polar...

... assisted or emulsion flotation in combination with centrifugation. These partiy oil wettable solids are also capable of forming structures through interaction with free bitumen and naphtha, also present in the sludge. This type of structure formation would involve the process of immiscible liquid phase...

... Introduction The one characteristic of oil sand fine tailings which most determines its undesirable properties is its stability. Oil sand tailings sludge is persistent. A major objective of fundamental research on fine tailings is therefore to discover which components and which interactions...

... properties of the particles and the water but to a large extent also on the interparticle interactions. There are many physical forces which interact to keep the particulates in a stable suspended state. These are electrical repulsive forces, steric forces, hydration forces and van der Waals attractive...

... stability of sludge to consolidation but the relative role of organic/mineral or mineral/mineral interactions in determining the stability of the structure is not well understood. Electron microscopic techniques are discussed which might allow direct determination of the relationship between the various...

... Abstract The settling of a synthetic sludge and purified kaolinite in various liquid phases was studied in order to determine the collcidal forces of particle interaction responsible for flocculation. Hydration forces seem to be important in the interactions of quartz particles. More detailed...

These mechanisms were recently reviewed by Castor et al. (4) . They range from emulsification with entrapment through...

A consequence of high leak-off can be the severe curtailment of production due to formation matrix damage, adverse formation...
