... of 0.5 wt % concentration of MgCl2 and CaCl2. In this set, values of IFT between crude oil and the surfactant solution, and crude oil and the brines and also solution viscosity, and finally capillary number at different salinities were measured and ultimate recovery values were determined. To clean...

... the compressibility of the oil/micro- bubble mixture. Flow visualization studies using glass micro- models, such as that of Bora et al.3, did not reveal the growth of micro-bubbles however. Ostos and Maini4 investigated the role of the capillary number in the solution gas drive process. The capillary number...

...). Two-phase testing as a function of capillary number indicated an effective gas permeability very close to that measured by the explicit relative permeability measurements at saturations just higher than the critical condensate saturation. The condensate and gas permeabilities measured during...

... that have been put forward to explain the production behavior of fractured oil reservoirs with water drive or during water injection. Two series of experiment were implemented on transparent glass-etched micromodel; one without the gravity effects at various capillary number values (N c ) and mobility...

... Abstract Conventional Capillary Number theory predicts that residual oil will not be mobilized until a critical capillary number (2E-05) is exceeded. This theory was tested to determine residual oil saturation mobilization after the forced water imbibition. In the literature, high residual oil...

... with the production from the bottom end of the sand-pack, as well as with production from the top end. The experimental results are presented in terms of the oil and gas production behavior affected by the capillary number and gravity forces. The results indicate that the gravity forces do not significantly influence...

On the other hand, the 6chemical models in both simulators used an additional parameter which is indispensable in the calibration of the model, this is the change in the capillary number...
